Foreword

The Tomato Genetics Cooperative, initiated in 1951, is a group of researchers who share and interest in tomato genetics, and who have organized informally for the purpose of exchanging information, germplasm, and genetic stocks. The Report of the Tomato Genetics Cooperative is published annually and contains reports of work in progress by members, announcements and updates on linkage maps and materials available. The research reports include work on diverse topics such as new traits or mutants isolated, new cultivars or germplasm developed, interspecific transfer of traits, studies of gene function or control or tissue culture. Relevant work on the Solanaceous species is encouraged as well. Paid memberships currently stand at approximately 121 from 21 countries. Requests for membership (per year) US$20 to addresses in the US and US$25 if shipped to addresses outside of the United States should be sent to Dr. J.W. Scott, [email protected]. Please send only checks or money orders. Make checks payable to the University of Florida. We are sorry but we are NOT able to accept cash or credit cards. Cover. Design by Christine Cooley and Jay Scott. Depicted are “Tomatoes of the Round Table” as opposed to “Knights of the Round Table”. This year we celebrate the 50th Anniversary of the Tomato Breeders Roundtable (TBRT). See this year’s feature article for information on the history of the Tomato Breeders Roundtable.

Grant Opportunity: Request for Proposals for Tomato Germplasm Evaluation Funding is expected to be available again in fiscal year 2008 for evaluation of tomato germplasm. Proposals must be submitted through the Crop Germplasm Committee (CGC). All proposals will be evaluated according to the national need for evaluation data, the likelihood of success, and the likelihood that the data will be entered into GRIN and shared with the user community. Evaluation priorities established by the CGC (Table 1) will provide review criteria. When all other factors are equal, preference for funding will be given to supporting those proposals forwarded by CGCs that have not received prior funding. Proposals will be reviewed by the CGC and forwarded to the USDA for consideration. Proposals must be returned to the CGC Chair by November 9, 2007 so that reviews and rankings, can be forwarded to the USDA in Beltsville by December 3, 2007. Because of limited funds, the USDA cannot support all proposals submitted. Consequently, please be very frugal in your request for funds. In recent years, the USDA has caped budget allocations in the range of $15,000-$18,000 per project annually. The proposal format is outlined below. Please submit proposals electronically as a PDF file to David Francis, CGC Chair, [email protected].

I. Project title and name, title of evaluators. II. Significance of the proposal to U.S. agriculture.

III. Outline of specific research to be conducted including the time frame involved – include the

number of accessions to be evaluated.

IV. Funding requested, broken down item by item. Budgets should follow USDA form ARS454 as funding will be in the form of a specific cooperative agreement. No overhead charges are permitted.

V. Personnel:

A. What type of personnel will perform the research (e.g. ARS, State, or industry scientist; postdoc; grad student, or other temporary help).

B. Where will personnel work and under whose supervision.

VI. Approximate resources contributed to the project by the cooperating institution (e.g. facilities, equipment, and funds for salaries).

A Look Back at the Tomato Breeders Roundtable J.W. Scott1 with contributions from Allan Stoner2, Paul Thomas3, and Jim Strobel4

1University of Florida, IFAS, Gulf Coast Research & Education Center, 14625 CR 672, Wimauma, FL 33598, USA email: [email protected] 2Retired-formerly USDA, Beltsville MD,3Retired-formerly PetoSeed Co., 4Retired, formerly University of Florida, Tropcial Research & Education Center Introduction.

The Tomato Breeders Roundtable (TBRT) has been the premier meeting in North America for public and industry scientists interested in tomato improvement and it attracts researchers from around the world. The TBRT has a proud tradition but there is no institution or governing body that carries it forward from year to year. Rather the meeting is passed on from host to host analogous to a baton being passed between runners in a relay race. Accordingly, hosts of the meeting often feel more tired once their meeting is finished than a relay racer does after the race! Since there is no institution, there are no official archives and before all information on the history of the TBRT is lost, a retrospective seemed appropriate because modern day tomato researchers owe much to our innovative predecessors. Be a part of this work in progress.

Of course the TBRT predates the electronic age of personnel computers and the internet. This article will take advantage of the present time period by being electronically interactive with any of you who can help with this article. Information presented will be incomplete and there may be some inaccuracies although the latter will hopefully be minimal. Hard copy will be in the 2007 TGC but I ask your help if you can make additions/corrections. Send information to me (see contact information above) and it will be updated for the web version that will be on the TGC website. So please consider this a working draft and thanks in advance for any assistance in making this historical review the best it can be. I can send an electronic version for editing in track changes if requested. If you know of someone who may have information but is not likely to see this, please send them a copy for their input. Together we can make this review the best it can be. All corrections and additions are welcome. I apologize for any inaccuracies or omissions, I did what I could with information at my disposal.

Abstracts and programs of recent meetings will be posted on the TGC website. It would be possible to list programs and abstracts from at least some of the earlier meetings on the TGC website over time if there is interest. Let me know what you think about this. Happy 50th Anniversary

Early information was obtained by contacting the contributors listed above. Allan Stoner mentioned that the impetus for the formation of TBRT was a group of people primarily interested in the Midwest canning industry in the 1950‟s. A search of early TGC‟s for information struck gold when an article by Mark Tomes of Purdue was found in The Report of the Tomato Genetics Cooperstive in 1958-volume 8:4. This report by Dr. Tomes follows:

The Tomato Breeders Group Several years ago an informal organization of tomato breeders was started by those attending a field day at Purdue University. Present were experiment station and university personnel from states adjacent to Indiana and tomato breeders from commercial seed houses and commercial processing corporations in the area. Dr. E.C. Stevenson of Purdue was asked to be chairman of the first steering committee which was charged with setting up a round table discussion of certain practical breeding problems. Since Drs. Alexander and Paddock had held an informal field day the prior year at Ohio, Drs. Thompson and McCollum volunteered to act as hosts for the group. Accordingly, a Tomato Breeders Round Table was held at Illinois in January of 1957. With the help of the Raw Products Research Bureau of the National Canner‟s Association, this meeting received somewhat wider publicity. Attendance included about 40 tomato breeders from areas as distant as Nebraska, New York and New Jersey. A new steering committee composed of representatives from the seed trades, the commercial processing corporations, and the universities was charged with setting up a combined field-day, discussion sessions for the summer of 1957. The Ohio group volunteered to sponsor the group and the August 8-9 session at Wooster resulted. Attendance at this session totaled around 70 with breeders present from areas as distant as Cuba, Canada, Texas, and California To date the Breeders group has operated on an informal basis. No formal organization exists, no proper name has been assigned, no dues are assessed, and no requirement for attendance exists other than an interest in the solution of practical tomato breeding problems. Those who founded the group had no intention of sponsoring another national organization. Rather, they were interested in the stimulation and practical knowledge that might be derived from the association of individuals who share a common problem. The original invitations were largely an area affair. If the group has grown, it attests only to a more widespread interest in the benefits to be derived from such an association. The group included those who feel that a solution to current tomato problems can best be achieved by the mutual discussion of methods. Others feel that methods can best be discussed with the materials at hand. To date we have had both methods sessions, and field-day, discussion meetings. Much of value in a how-to sense has been derived. Some cooperation has been stimulated, and considerable knowledge of who is doing what, how, and why has been gained. The question whether this group might conflict with TGC was discussed at an early meeting. The feeling of the group was that no conflict would result since the emphasis of the two groups was different. A session for 1958 is in the planning stage. Dr. Munger kindly consented to act as sponsor for the group at Cornell in connection with their 1958 vegetable days. Recently, however, we have had a number of requests asking that the session be scheduled in or near Indiana just preceding or following the AIBS session at Bloomington in order that travel might be reduced for those wishing to attend. An announcement will be sent to all those who have indicated an interest by past attendance.

For the steering committee, Mark L. Tomes

It can be seen from Tomes‟ report that the first reference for the group to meet under the name “Tomato Breeders Round Table” was for a meeting at Illinois in 1957. Thus, 2007 marks the 50th Anniversary of the Tomato Breeders Roundtable!! As for the name, “Round Table” was used for


9

30 years until 1988 when Mike Courtney was host and used the word “Roundtable”. The single word has been in favor ever since. The Meetings. Table 1 lists meeting dates, locations and program chairs or hosts. Note there are gaps where some of you may be able to add information and there may also be some omissions or corrections that need to be made. I started going to the TBRT in 1976 and have reasonably good information for most meetings since then.

The TBRT actually met twice in 1957 but settled in to meeting once a year until 1979. There used to be steering and program committees appointed to carry out the meetings. According to Allan Stoner, the Food Processors initially kept the mailing list and treasury. After that Bill Hepler did it when he was at Penn State and then Allan Stoner maintained he records for several years in the 1970‟s. Since the 1981 meeting, mailing lists and extra meeting funds have been passed on to the host of each meeting. Of the early meetings Allan Stoner recalled “Initially, and for the first several years, the TBRT met at the LaSalle Hotel in Chicago in February. Later someone suggested in would be a good idea to meet in a warmer climate in Feb and also be able to see some tomatoes when we met, thus the meeting sites started moving around each year (not always to where there were tomatoes growing at the time; Columbus, OH, Indianapolis, College Park MD, etc.)”. Paul Thomas of PetoSeed kindly provided this synopsis of the early years. “The first meeting (sic) was held in Cleveland in 1959. At that time there was a revolution going on with tomatoes, a lot happening and there were individuals in both the land grant colleges and industry that felt the need for such a group. Mechanical harvesting of processing tomatoes was in the process of making its debut. Michigan State and UC Davis were the primary universities in the development of harvesters and tomato varieties for this program. Along with the mechanical harvest of tomatoes was work with disease resistance of the tomato. All of these programs were expanding in the late 1950‟s and early 1960‟s. In addition, the use of F-1 hybrid tomatoes for the commercial trade was making its appearance. This transition from O.P.‟s to F-1‟s was initiated primarily by Peto Seed Co. and the Joseph Harris Seed Co. As you can see, there was a lot going on in the industry and there was a definite need for an organization such as TBRT to help coordinate this change and it was a great way for scientists to meet and exchange material and ideas. In 1960, the next meeting of TBRT was moved to the La Salle Hotel in downtown Chicago where it remained for a number of years. It was felt this was more or less the center of the U.S. and accessible for people from the east, west, and south to meet. The early meetings were primarily along the practical applied type research. This seemed to be where the greatest need was. After the first few years in Chicago, it was decided to move the meetings around to various cities. Some of the early cities we visited were Denver, CO; Bradenton, FL; Homestead, FL; San Francisco, CA; and also Sacramento, CA. At about this time frame there were over 200 people working with tomatoes in almost all the land grant colleges, even Nebraska, Idaho, Montana, and Wyoming of all places. There was a great deal of interest particularly in the mechanical harvest programs that were going on. This was really a great period to be involved in the industry. A lot was going on and looking back a great deal was accomplished and the total industry, both fresh market and processing changed.” Jim Stobel had these comments: “While the early years of the TBRT involved principally processing interests, programs such as ours in Fla. were enhanced in many ways by the TBRT meetings and the day to day cooperation that originated at such meetings. In summary, the major benefit of this meeting of research personnel from the University and private business sector was the early stage sharing of valuable information and germplasm for all, of the acceleration progress for


10

individual programs (and growers) by months or years. As everyone knows, publication and variety releases take years to become part of the communications network, the TBRT provided a valuable forum for all who participated”. We can all agree that the climate of free germplasm exchange has certainly changed over the last several decades! As mentioned the TBRT was an annual meeting until1979. Several things were changing during this era: there was a decline in public breeding programs which provided a major share of the presentations at the meetings; the Midwestern canning industry, so important to the formation of the TBRT, was rapidly losing acreage and factories; and biotechnology was being born and these scientists went to other meetings to present their findings. For several years there were discussions as to whether the TBRT should meet once a year or every two years. This was finally resolved when it became a trend to meet about every 1 ½ years although the actual times of the meetings are determined in large part by the host of the next meeting. As can be seen in Table 1 all meetings have been in North America with most in the USA except for one in Canada, two in Mexico, and one in Guatemala. As indicated, the early meetings dealt largely with sharing practical methods for crop improvement during an exciting era when research published in the TGC and elsewhere was making the tomato a model genetic crop. There was more discussion at TBRT‟s than most meetings with the presentations being less formal as indicated by the name Round Table. Over the years the meetings have become more formal with a higher percentage of research presentations, but panel discussions and extensive questioning are still cornerstones of this meeting that sets it apart from most scientific meetings. Area reports are presented from around the world to keep the group up to date with emerging disease, variety, and other issues. The Tomato Crop germplasm Committee regularly meets at the TBRT and updates are given to the group on its activities. There are also reports from the germplasm center at Geneva, NY and Davis, CA as well as a brief report from the TGC Editor. With the advance of molecular technology many presentations are now molecular in nature but still with applied goals in mind for MAS etc. With the tomato genome presently being sequenced future meetings will likely have more and more functional genomics presentations that will be aimed at improved breeding efficiency. More basic genomics studies will be for the most part presented elsewhere. The Pioneers.

One of the goals of this paper is to pay tribute to “our tomato breeding forefathers”. Although some key people will be left out that should not preclude mentioning some of the key figures who got the TBRT going and made it successful. Allan Stoner provided the following narrative: “I am pretty sure that the group was formed by a group of Experiment Station tomato breeders from several Midwestern states. Of course at that time most states had a tomato breeding program and some (Ohio, Florida, California) had two or more. My recollection is that people like Walter Brown -Ohio, Mark Tomes and E.C. Stevenson or Ken Johnson -Purdue, Shig Honma-Michigan, Anson Thompson or his predecessor at Illinois, Vic Lambeth -Missouri , Currence -Minnesota, etc. I am certain there were other Midwestern breeders involved and there may have very well been breeders from other regions involved in starting the organization as well. The National Canners Assn , later the National Food Processors Assn, was involved for many years and maintained the mailing list and collected registration fees, etc. Charles Mahoney, then Ed Crosby, and Bill Hollis were involved from the NCA. When I went to my first meeting in 1964, there were attendees from all over the country -


11

Jack Hanna and Paul Smith from CA, Jim Walter and Jim Strobel from FL, Paul Leeper from TX, Carroll Barnes -Clemson, etc. There were also several processing company breeders such as Walter Virgin from Del Monte, Charlie John from Heinz, Larry Holl and Colen Wyatt from Libbys, Moore and ? (famous for recording bird calls) from Campbell Soup, etc. There were also some seed company breeders such as Paul Thomas, Tom Castle, a guy named Scott you may have known and Carl Cadregari from Harris. Other than Canadian breeders from Guelph and Beaver Lodge, Canada, I don't recall any foreign participants until later years. Jim Strobel mentioned cooperating with “Charlie John and Colon Wyatt of the H.J. Heinz Co. as well as with George Reynard and John Moore of the Campbell Soup Co. to develop stocks with a greater diversity of vine and fruit characteristics such as advances in fruit color, firmness, and jointless pedicel. We also cooperated with Paul Smith of U. of California, L.J. Alexander of Ohio State, and Jim Gilbert of Hawaii whose work in fresh market tomatoes for a variety of cultural situation and disease resistance were highly significant” Jim especially mentioned Jim Walter for his multiple disease resistant breeding work at the University of Florida. TBRT members paid tribute to Dr. Walter with a signed plaque at the 1968 meeting after his untimely death.

Paul Thomas adds “There were a number of memorable scientists that attended these early meetings. Of course, most were those that fit the „character‟ designation. These included Prof. T.O. Graham of Guelph, Ontario Canada, P.A. Young of Texas, Charlie John of J.H. Heinz Company and, of course, if you wanted to, you could include your dad “Scottie” in this group.” If you will indulge me I will add that as a boy interested mostly in sports I do have distinct memories of my father going to this meeting called the Tomato Breeders Round Table in Chicago in the winter. It was due to the Round Table in the name that it stuck with me over all the other types of meetings my father took off to. I always felt he had a good time at the meetings and although I‟m sure the fun was harmless it was probably best that my mother didn‟t know everything about the trips. Later, one of my fond memories was attending the TBRT in Culiacan, Mexico in 1978 with my father (& my mother who was also there). The Future. With so many intriguing tomato problems yet to be solved the TBRT should thrive for many decades to come. This will depend on the next generations of tomato researchers accepting the „tomato baton‟ and carrying on the legacy briefly outlined here. From what I see from all the clever young people working on tomato the prospects for the TBRT are bright indeed.

Occurrence of Anthocyanin in Cultivated Tomato Peter S. Boches and James R. Myers Department of Horticulture, Oregon State University, Corvallis, OR 97331 email: [email protected], [email protected] Introduction The cultivated tomato (Solanum lycopersicum) does not normally produce anthocyanins in fruit tissues (Jones et al., 2003). However, in the course of developing a high anthocyanin tomato cultivar at Oregon State University using genes introgressed from wild species, we have noticed several cultivated tomato lines (with no wild species apparently in their pedigrees) that produce anthocyanin in fruit tissues, especially in green shoulder (u+u+) genotypes. In this article we verify the presence of anthocyanin in these lines using UV-visible spectroscopy. Materials and methods Plant Materials Plant materials were assembled from various sources and field grown in 2006 and/or 2007 at the Oregon State University Vegetable Research Farm in Corvallis, Oregon (Table 1). Fruit of ‘Purple Smudge’ were grown by Amy Goldman in Rhinebeck, NY and shipped to Oregon for analysis. A segregating population of anthocyanin fruited seedlings of ‘Dafel’ (an F1 hybrid) were obtained from seed saved from a single plant in a seed lot that was segregating for plant type and fruit shape. High anthocyanin breeding lines developed in our program and containing genes introgressed from wild species and non-anthocyanin containing tomatoes were included for comparison as well. The OSU high anthocyanin lines were created by crossing the accessions LA3734A (containing vio, a radiation induced mutant with high anthocyanin stems and veins), LA3736 (containing atv, a gene introgressed from S. cheesmanii LA0434 that causes high anthocyanin in stems and leaves), LA1996 (containing Aft, a gene introgressed from S. chilense that causes anthocyanin accumulation in the fruit), and LA3668 (containing Abg, an anthocyanin fruit gene introgressed from S. lycopersicoides). Although most of our stable high anthocyanin lines (e.g. P20) have LA3668 (Abg) in their pedigree, they probably do not contain Abg, since Abg can not be maintained in a homozygous state due to an inversion on the lower arm of chromosome 10 in S. lycopersicoides relative to S. lycopersicum (Canady et al., 2006). Anthocyanin Extraction and Measurement The most highly pigmented fruit from a given line or F2 individual were selected for analysis. For stable breeding lines and named cultivars, each fruit was taken from a separate plant. For F2 individuals, multiple fruit from a single plant were sampled. In 2006, extractions were performed on frozen fruit. In 2007 extractions were performed on fresh fruit. In general, ripe fruit were selected for extraction. However, for ‘Purple Smudge’ and the ‘Dafel’ segregant progeny, extractions were performed on both ripe and green fruit. Anthocyanins were extracted in acidified methanol using a micro-prep method. Briefly, all pigmented tissue (including the epidermis and some of the pericarp, referred to hereafter as ‘peel’) was removed



15

from single fresh fruit and ground into a fine powder with liquid nitrogen in a mortar and pestle. Fruits were weighed before and after removing the peel to determine the total amount of pigmented tissue. A weighed sub-sample of the homogenized powder was extracted overnight in 300 µl of 1% HCl methanol at 5° C. For the material grown in 2006, a 100-300 mg sub-sample weighed to the nearest 10 mg was used. In order to increase the accuracy of the procedure, in 2007 a 75-150 mg subsample weighed to the nearest 0.1 mg was used. The extraction volume was brought to 500 µl with nanopure water and 500 µl of chloroform was added to the tube. The tubes were centrifuged for 5 minutes at 14,000 rpm and the aqueous phase was removed to a new tube. The presence of anthocyanins was verified by reading absorbance of the samples from 220-750 nm. Monomeric anthocyanin content was measured using the pH differential method as described by Giusti and Wrolstad (2001). For the pH differential method, the samples were diluted 1:5 with the pH buffer and absorbance was read at an observed λvis-max of 540 nm. The predominant anthocyanin in tomato fruit has previously been reported to be petunidin-3-(p-coumaryl)-rutinoside-5-glucoside (Mes, 2004). For the calculation of the monomeric anthocyanin pigment content, a molecular weight of 934 and a molar absorptivity (ε) of 17000 was used, corresponding to petunidin-3-(p-coumaryl)-rutinoside-5-glucoside in acidified methanol (Price and Wrolstad, 1995). Milligrams anthocyanin per 100 grams of pigmented tissue (peel) on a fresh weight basis was calculated as ((mg/L extract * total volume of extract)/grams peel sampled)*100. Milligrams anthocyanin per 100 grams whole fruit was calculated as (((mg/g peel)*(peel weight in g))/total fruit weight in g)*100. Results and Discussion The spectral characteristics of anthocyanin extracts from several tomato cultivars clearly showed that some cultivated tomatoes produce small amounts of anthocyanin in the fruit (Figure 1). In tomato cultivars with very small amounts of visible anthocyanin, such as ‘Yellow Pear’ and ‘Oregon Spring’, an absorbance peak at 540 nm was present but only weakly visible (not shown). In cultivars with modest amounts of anthocyanin such as the ‘Purple Smudge’ (Fig. 1B) and ‘Dafel’ segregant progeny (Fig. 1C), the peak at 540 nm matched that of the high anthocyanin genotype P20 x hp-2dg (Fig. 1A) and clearly differed from the profile of an extract of a tomato with the aa (anthocyanin absent) phenotype (Fig. 1D) or that of ‘Legend’ (not shown). Monomeric anthocyanin contents of the tomato fruit extracts (Table 2) were comparable to those reported by Mes (2004) and Jones et al. (2003) for tomato skin. Mes reported an average value of 13 mg/100 g FW skin for Aft-/atvatv genotypes, and a maximum value of 300 mg/100 g FW skin for Abg-/atvatv genotypes. The value reported by Mes (2004) for Aft-/atvatv skin was lower than that reported by Jones et al. (2003) for Aft skin (~20-60 mg/100 g FW). Mes attributed these differences to the extraction method, which included more of the pericarp tissue in Mes’ extractions. The extraction procedure used here was probably more similar to that of Mes (2004). The value reported here for Aft skin (~30 mg/100 g FW peel) is intermediate between the two. The value reported here for Abg-/atvatv genotypes (84 mg/100g FW peel) is lower than that reported by Mes (2003). None of the anthocyanin containing cultivars or their segregants had levels of anthocyanin higher than LA1996 (Aft). However, the anthocyanin content of ‘Purple Smudge’ (20 mg/100g FW peel) and the ‘Dafel’ segregant (14.07 mg/100 g FW peel) were close to LA1996 (27.02 mg/100 g FW peel) and the difference was not significant. There was a high coefficient of variation (e.g. ~8-60% for the mean


16

mg/100 g peel in the 2006 data set) in the monomeric anthocyanin content of fruit extracts. This is a common issue in the analysis of plant secondary metabolites (Sumner et al., 2003) and was expected because anthocyanin accumulation in tomato fruit is highly dependent on exposure to light. Sumner et al. (2003) suggest that the average biological variance in plant metabolites for Medicago truncatula is 50%. The lines selected for high anthocyanin accumulation in our program (e.g. P20) typically have a very sparse canopy to allow good light penetration to the fruit. Smaller fruited types (e.g. P4 x ‘Sungold’ small fruited F2) were very high in anthocyanin on a whole fruit basis as a result of their increased surface area:volume ratio, as previously reported by Mes (2003). The ‘Dafel’ segregant and its progeny are characterized by a very strong green shoulder, sometimes with streaks that descend midway down the fruit. In addition, the green fruit appear to be higher in anthocyanin than ripe fruit, similar to the anthocyanin accumulation pattern observed in some pepper cultivars such as ‘Riot’ or ‘Marbles’. Seed from the ‘Dafel’ segregant was planted in 2007 and the population varied significantly in the amount of green shoulder present on individual plants. Anthocyanin expression was correlated with the degree of green shoulder present, with anthocyanin expression limited to the green shoulder. Anthocyanin expression is limited to the green shoulder in ‘Oregon Spring’ as well. We have also noticed a correlation between green shoulder and anthocyanin expression in material derived from Aft and atv, such as P20. Further work on this topic by our lab may include HPLC analysis of the anthocyanin extracts from tomato cultivars such as ‘Purple Smudge’, ‘Dafel’ segregants, and ‘Oregon Spring’ and allelism tests between these cultivars and known anthocyanin fruit genes.

Thifensulfuron susceptibility in tomatoes and possible linkage with blossom end rot Jim Dick, Tomato Solutions, 23264 Mull Road, Chatham, Ontario, Canada N7M 5J4 [email protected] Thifensulfuron (brand name Pinnacle in Canada) is a broadleaf herbicide registered on processing tomatoes in Canada. It is applied as an overall spray about 3-4 weeks after transplanting. Some hybrids and inbred lines are quite susceptible to the herbicide. An inbred line called N1069 was found to have about 10% susceptible plants. Except for the susceptibility to thifensulfuron, the plants were identical to the resistant plants. It was assumed therefore that a mutation had arisen spontaneously. Seed was saved from both resistant and susceptible lines and grown out to confirm resistance and susceptibility. The two lines bred true for either resistance or susceptibility with no segregation, and appeared exactly identical for all horticultural traits. The F1 hybrid was made between the two lines, and F2 seed was produced and grown out. The F2 population segregated for resistance and susceptibility in a 3:1 ratio indicating that there was a single recessive gene involved. Crosses made with another thifensulfuron susceptible inbred line called CC390 also indicated that a single recessive gene was involved. Hybrids using the susceptible N1069 crossed with resistant lines were all resistant. Under extremely dry conditions, it was found that the susceptibility to thifensulfuron was associated with susceptibility to blossom end rot in the N1069 inbred lines.

Co-dominant SCAR marker for detection of the begomovirus-resistance Ty-2 locus derived from Solanum habrochaites in tomato germplasm

Brenda E. Garcia1,3, Elaine Graham2, Katie S. Jensen1, Peter Hanson2, Luis Mejía3 and Douglas P. Maxwell1 1University of Wisconsin-Madison, Madison, WI 53706 2Asian Vegetable Research Center- the World Vegetable Center, Taiwan 3Universidad de San Carlos, Guatemala

Email: [email protected] Introduction: Begomoviruses are a major threat to tomato production in most sub-tropical and tropical regions (Anderson and Morales, 2005). These geminiviruses are transmitted by the whitefly (Bemisia tabaci) complex and thus, many management strategies have focused on use of insecticides. Integrated Pest Management strategies include virus-free seedlings, host-free periods, management of time and location of planting, and begomovirus-resistant hybrids (Salati et al., 2002). Breeding begomovirus-resistant hybrids has involved the introgression of resistance genes from wild tomato species. Hanson et al. (2000) mapped the introgression from Solanum habrochaites, which conditioned resistance to Tomato leaf curl virus, to the long arm of chromosome 11 between TG36 (84 cM) and TG393 (103 cM) in the breeding line H24. This resistance gene was designated Ty-2 (Hanson et al., 2006) and was reported to be associated with an introgression from TG36 (84 cM) to TG26 (92 cM). Maxwell and Mejía (2002, unpublished data) developed PCR primers from the sequence of the TG105A (90 cM) marker and amplified PCR fragments from the susceptible tomato, M82-1-8 (EU053434), H24 (EU053432) and S. habrochaites LA1223 (EU053433). Sequence alignments showed that H24 was nearly identical to the S. habrochaites and very different from M82-1-8. Recently, Garcia and Maxwell (unpublished data) sequenced PCR fragments for the marker TG105A for begomovirus-resistant breeding lines with resistance derived from Solanum chilense and found that these lines had an introgression in this region (eg., Gc143-2, EU053431). This introgression was very different from the one in H24, and it might be an introgression for the I2 gene (91.5 cM), which is present in Gc143-2. Because of this potential confusion, it was decided to search for a better marker for the Ty-2 locus. PCR primers from the SGN website for T0302 (89 cM), C2-At5g25760 (89.5 cM), and Hba78A16T7 (89.7 cM) were used. This report describes two co-dominant SCAR markers developed from the sequence of the RFLP marker T0302 for lines with the Ty-2 locus. PCR methods: DNA was extracted from fresh leaves of plants with PUREGENE® DNA Purification Kit (Gentra Systems, Inc., Minneapolis, MN) and DNA was adjusted to approximately 10 ng/µl. PCR parameters were for 25-µl reactions containing 2.5 µl 2.5 mM dNTPs, 5 µl 5x buffer, 2.5 µl 2.5 mM MgCl2, 0.1 µl (0.5 units) GoTaq DNA polymerase (Promega Corp., Madison, WI), 2.5 µl each forward and reverse primer at 10 μM, 2-5 µl of DNA extract, and water. PCR cycles were 94 C for 4 min, 35 cycles of 94 C for 30 sec, 55 C for 1 min or 53 C for 1.5 min, and 72 C for 1.5 min. These cycles were followed by 72 C for 10 min, and then the reaction was held at 4 C. PCR reactions were performed in the MJ DNA Engine PT200 Thermocycler™ (MJ Research Inc., Waltham, MA). PCR-amplified fragments were separated by gel electrophoresis with 1.5 or 2% agarose in 0.5 X TBE buffer and stained with ethidium bromide and visualized with UV light. ssDNA was digested in PCR reactions with shrimp alkaline phosphatase (Progmega Corp.) and exonuclease I (Epicentre,


22

Madison, WI), and the PCR-fragments directly sequenced with Big Dye Sequencing Kit™ and analyzed by the Biotechnology Center, University of Wisconsin-Madison. The SGN primers for T0302 (T0302F/T0302R) and TY-2R1 were used at extension of 55 C and those for C2-At5g25760 (C2-11-89F/C2-11-89R), and Hba78A16T7 (BAC-11-89F/BAC-11-89R) were used at extension of 53 C. The SGN primers for T0302 are:

TG0302F, 5’ TGGCTCATCCTGAAGCTGATAGCGC TG0302R, 5’ AGTGTACATCCTTGCCATTGACT

A reverse primer was designed from the sequence of the T0302 fragment: TY-2R1, 5’ TGAT(T/G)TGATGTTCTC(T/A)TCTCT(C/A)GCCTG Results and Discussion: Initial comparisons involved the susceptible line, M82-1-8 (ty-2/ty-2), and the resistant line, H24 (Ty-2/Ty-2). The PCR fragment sizes for the markers C2-At5g25760 and Hba78A16T7 were ca. 1.3 kb and 760 bp, respectively. Interestingly, the PCR primers for the T0302 marker gave ca. 800-bp and ca. 900-bp fragments for M82-1-8 and H24, respectively (Fig. 1, lane 2 and 4). 1 2 3 4 5 6 7

The sequences for the three markers (T0302, Hba78A16T7, and C2_At5g25760) for the susceptible line M82-1-8 (EU046613, EU053430, EU053428, respectively) were different from the respective marker sequences from the resistant line H24 (EU046610, EU053429, EU053427, respectively). These results clearly indicated that H24 had an introgression at these three marker locations. Since the marker T0302 seemed to have the greatest potential as a SCAR marker for the Ty-2 locus, PCR fragments from two additional begomovirus-resistant lines (GIh902 and Gc143-2), which had begomovirus-resistance genes (Ty-1 and Ty-3 loci on chromosome VI, Maxwell et al., 2006) most likely derived from S. chilense, were sequenced. The sequences for GIh902 and Gc143-2 for this T0302 fragments (792 bp) were identical to those of M82-1-8. This was in contrast to the sequences for the TG105A marker, where the Gc143-2 and GIh902 seqeunces were identical but different from the sequence for M82-1-8. Both Gc143-2 and GIh902 have tested positive for the I-2 gene and M82-1-8 tested negative for this gene (Salus and Maxwell, pers. com.).

When the sequences for the T0302 PCR fragment for M82-1-8 and H24 (909 bp) were compared, there were 36 SNPs, and four indels (four indels of 1 nt, one of 2 nt, one of 3 nt, and one of 120 nt). The sequence for the T0302 marker from S. habrochaites LA0386 (909 bp, EU046611) was identical to the sequence from H24. The sequence for the T0302 marker (789 bp, EU046612) was also obtained for another accession, S. chilense LA2779, that has been used as a source of

begomovirus-resistance genes (Agrama and Scott, 2006); and the T0302 sequence for LA2779 was different from those for both M82-1-8 and H24. Most notably, the 120-nt indel associated with the fragments from M82-1-8 and H24 was not present between the M82-1-8 and LA2779 sequences for T0302. These results support the presence of an introgression from S. habrochaites in H24 at this marker. This primer pair T0302F/T0302R produced two bands (800 and 900 bp) for the commercial hybrid TyQueen (Green Seeds Co., Vietnam), which is reported to have Tomato yellow leaf curl virus-resistance derived from Ty-2 gene. When tested in Guatemala in October 2006, TyQueen was moderately resistant to begomoviruses. When this primer pair was tested with additional germplasm with the Ty-2 locus from the Asian Vegetable Research and Development Center (AVRDC), CLN2460E gave the 900-bp fragment, and two lines that had shortened introgressions for the Ty-2 locus (P. Hanson, pers. com.) also gave one 900-bp fragment. Fifty-nine breeding lines and hybrids have been evaluated with these primers (T0302F/T0302R) and no unexpected results were obtained. A reverse PCR primer, TY-2R1, was designed from the alignment of the sequences for M82-1-8 and H24 in order to produce smaller fragments for both the susceptible and resistant genotypes. The PCR primers T0302F/TY-2R1 gave a 600-bp fragment with two AVRDC lines with the Ty-2 locus, and a 450-bp fragment for three inbred lines and one hybrid all of which lacked the Ty-2 locus. Three F1 plants known to be heterozygous for the Ty-2 locus all gave three PCR fragments, 450, 600, and 700 bp (Fig. 2). The sequences of the 450- and 600-bp fragments were as expected. The 700-bp fragment is most likely a heteroduplex between the 450- and 600-bp fragments. 1 2 3 4 5 6 7 8 9 10

Note: TY172 and TY197 are resistant to begomoviruses, but lack the Ty-2 locus. HUJ-VF is an inbred line from Hebrew University of Jerusalem. Conclusions: The two sets of primers, T0302F/T0302R and T0302F/TY-2R1, effectively detected the two genotypes, Ty-2/Ty-2 and Ty-2/Ty-2, and the T0302F/TY-2R1 primer set also gave clearer bands with the heterozygous plants than the T0302F/T0302R primers. No false positives were detected, when 59 inbred lines and hybrids were evaluated. But it is possible that this marker might not detect all lines that have the Ty-2 gene, since it is not known how closely linked this marker is to the Ty-2 gene. These T0302 primers are a better marker than a TG105A CAPS marker (Graham and Hanson, pers. com.), as the latter marker may also detect an introgression that might be associated with the I2 gene, and this would result in false positives.

Agr. Email: [email protected] Breeding for resistance to begomoviruses in tomato can be greatly aided by the availability of PCR-based markers for the various resistance loci. Four begomovirus-resistance loci or regions have been mapped to chromosome 6 (Agrama and Scott, 2006; Chagué et al., 1997; Ji and Scott, 2006b; Ji et al., 2007; Zamir et al., 1994). The Ty-1 locus, which is part of the introgression derived from Solanum chilense LA1969, is located between markers TG297 (4 cM) and TG97 (8.6 cM) (Zamir et al., 1994). Agrama and Scott (2006) reported three regions that contributed to resistance in breeding lines with introgressions from S. chilense LA2779 or LA1932. One region corresponded to the region having the Ty-1 locus. Another region was the Ty-3 locus, which was mapped to a region between cLEG-31-P16 (20 cM) and T1079 (27 cM) (Ji and Scott, 2006b; Ji et al., 2007). The third region was near the self-pruning (sp) and potato leaf (c) loci. Another begomovirus-resistance QTL, derived from an introgression from S. pimpinellifolium, was mapped near the marker TG153 (33 cM; Chagué et al., 1997).

Previously, Ji and Scott (2006a, 2006b; Ji et al., 2007) reported the development of SCAR and CAPS markers linked to begomovirus resistance genes derived from S. chilense on chromosome 6, and they determined that the Ty-3 locus mapped to a region that included the FER locus (25 cM, BAC clone 56B23, AY678298). Jensen and Maxwell (Maxwell et al., 2007) found that the sequences for the G8 gene of the BAC clone 56B23 are different for lines derived from LA2779 and LA1932. To differentiate the two introgressions, the one from LA2779 is designated Ty-3 and the one from LA1932, Ty-3a. This report describes two sets of PCR primers that provide co-dominant SCAR markers for detection of the Ty-3 and Ty-3a introgressions. Primer Design: Initially, PCR primers were designed to amplify sequences near the 5’ end of the BAC clone 56B23. These primers were used to amplify PCR fragments from the begomovirus-susceptible heritage tomato, S. lycopersicum ‘Purple Russian’, and a begomovirus-resistant breeding line, Gc43-3, from the tomato breeding program at San Carlos University, Guatemala with an introgression in this region from S. chilense LA2779 (Mejía et al., 2005). These sequences were aligned, and forward and reverse primers designed from conserved regions: forward primer FLUW-25F (5’ CAAGTGTGCATATACTTCATA(T/G)TCACC) and reverse primer, FLUW-25R (5’ CCATATATAACCTCTGTTTCTATTTCGAC). As expected, these primers gave PCR fragments for S. lycopersicum and the S. chilense introgression of 475 and 641 bp, respectively. A third primer pair was designed to give smaller PCR fragments from the aligned sequences of the FLUW25 fragment

for the forward primer and sequences 3’ of the FLUW-25R primer for the reverse primer: forward primer, P6-25-F2, 5’ GGT AGT GGA AAT GAT GCT GCT C, and reverse primer, P6-25-R5, 5’ GCT CTG CCT ATT GTC CCA TAT ATA ACC. The P6-25-F2/P6-25-R5 primers were expected to give fragment sizes for S. lycopersicum and the S. chilense LA2779 introgression of 320 bp and 453 bp, respectively. DNA Extraction and PCR Methods: DNA was extracted from fresh leaves of plants with PUREGENE® DNA Purification Kit (Gentra Systems, Inc., Minneapolis, MN) and DNA adjusted to approximately 10 ng/µl. PCR parameters were for 25-µl reactions containing 2.5 µl 2.5 mM dNTPs, 5 µl 5x buffer, 2.5 µl 2.5 mM MgCl2, 0.1 µl (0.5 units) GoTaq DNA polymerase (Promega Corp., Madison, WI), 2.5 µl each forward and reverse primer at 10 μM, 2-5 µl of DNA extract, and water. PCR cycles were 94 C for 4 min, 35 cycles of 94 C for 30 sec, 53 C for 1 min, and 72 C for 1 min. These cycles were followed by 72 C for 10 min, and then the reaction was held at 4 C. PCR reactions were performed in the MJ DNA Engine PT200 Thermocycler™ (MJ Research Inc., Waltham, MA). PCR-amplified fragments were separated by gel electrophoresis with 1.5% agarose in 0.5 X TBE buffer, stained with ethidium bromide, and visualized with UV light. ssDNA was digested in PCR reactions with shrimp alkaline phosphatase (Promega Corp.) and exonuclease I (Epicentre, Madison, WI) and the PCR-fragments were directly sequenced with Big Dye Sequencing Kit™ and analyzed by the Biotechnology Center, University of Wisconsin-Madison. Results and Discussion: The FLUW-25 primer pair amplified fragments of 480 bp and 640 bp from the susceptible line S. lycopersicum Heinz 1706 and from the begomovirus-resistant breeding line, Gc43-3, with an introgression from S. chilense LA2779, respectively. Surprisingly, the Gh25-3 breeding line, which was derived from the begomovirus-resistant line Ih902 (see line 902 in Vidavsky and Czosnek, 1998) with resistance reported to be from an introgression from S. habrochaites, also gave a 640-bp fragment. The heterozygous plant, Gh228-1, with resistance from Ih902, gave the two sizes, 480 and 640 bp, for the Ty-3/ty-3 genotype (Fig. 1). 1 2 3 4 5 6

The sequences for the FLUW25-PCR fragments from Heinz (475 bp) and Gc43-3 (641 bp) were aligned; and there were 18 SNPs and 5 indel differences (Maxwell et al., 2007). Single indels of 3, 6, 42, and 143 nt and two indels of 5 nt were present. The sequence for the fragment from Heinz had 100% nt identity with the sequence of the comparable region of the BAC clone 56B23. In another susceptible line, M82-1-8, the sequence for the 475-bp fragment was identical to that of Heinz. Surprisingly, the sequence for the 640-bp fragment from Gh25-3 with resistance from Ih902 had 100% nt identity with the fragment from Gc43-3. The two fragments from Gh228-1 had 100% nt identity with the 475- and 641-bp fragments from Heinz and Gc43-3, respectively. Additionally, the sequence of the 640-bp fragments from 11 other begomovirus-resistant breeding lines with resistance

27

from either S. chilense LA2779 or Ih902 had 99-100% nt identity with Gc43-3. These FLUW25 primers were used to evaluate the presence of the Ty-3 locus in 102 breeding lines from the tomato breeding program at San Carlos University, Guatemala (Mejía et al., 2005), and the results were as expected except for the Gc171 line. This line was known to have an introgression, Ty-3a, in this region derived from S. chilense LA1932, but no PCR fragment was amplified by these primers. van Betteray and Smeets (unpublished) determined that the FLUW25R primer did not anneal to S. chilense LA1932 sequences. Thus, several more reverse primers were designed from the same area of the BAC clone 56B23 sequence. These were evaluated with Gc171 or lines selected from Gc171 crosses. One primer, P6-25-R5, gave fragments with FLUW25F for S. chilense LA1932 derived lines. An additional primer set, P6-25-F2 and P6-25-R5, was designed to include the 143-nt ty-3/Ty-3 indel and to give smaller fragments than the FLUW25 primer set (Fig. 2). With begomovirus-resistant breeding lines derived from either the S. chilense LA2779 source, Gc9, or the Ih902 line (Vidavsky and Czosnek, 1998), the expected 450-bp Ty-3 fragment was obtained. A 320-bp ty-3 fragment was amplified from breeding lines lacking the introgression from either of these two begomovirus-resistance sources. A 630-bp Ty-3a fragment was obtained from lines derived from S. chilense LA1932, such as Gc171. Heterozygous hybrids were easily detected with these primers which amplified two fragments corresponding to the S. lycopersicum ty-3 fragment (320 bp) and either the Ty-3 (450 bp) or the Ty-3a (630 bp) fragment (Fig. 2). No F1 hybrids were available to test for fragments with the Ty-3/Ty-3a genotype, but it is expected that this primer pair would also amplify two fragments (450 and 630 bp) with this genotype. 1 2 3 4 5 6 7

The three sizes of the P6-25-F2/P6-25-R5 fragments were sequenced (Maxwell et al., 2007). The 320-bp and the 450-bp fragments corresponded to the sequences of S. lycopersicum and of the Ty-3 locus associated with lines derived from S. chilense LA2779, respectively. The 650-bp fragment from Gc171 had two large inserts, when compared with the S. lycopersicum sequence. Conclusions: These two sets of primers detect co-dominant SCAR markers, FLUW25 and P6-25, for the ty-3, Ty-3 and Ty-3a loci. It is not known how closely these markers are to the functional Ty-3 gene (Ji et al., 2007), so it is possible that some breeding lines would give false negative or false positive results. It is expected that these markers will be evaluated in various tomato breeding programs.

Antioxidants in Faculty Tomatoes N. Kedar Antioxidants which are present in fruits and vegetables may help prevent cancer, arthritis and heart disease. Tomatoes also provide an important source of human nutrition because of their widespread consumption in fresh and processed forms (1). Research was performed at Harvard Medical School and other universities with yeast and mammals. Plant polyphenols (including sirtuins and resveratrol) were found to block cancer formation, promotion and progression in animals. Resveratrol has also been shown in numerous clinical trials to benefit heart disease and increasing HDL (beneficial) cholesterol. The scientists conclude that plant polyphenols increase the response to stressful conditions, decrease cancer and extend lifespan. Most of the above experiments were performed with yeast and with mice, large scale experiments with humans (7) are planned for 2007 and the researchers stress that resveratrol is also active in human cells – suggesting a potential for lengthening life and preventing or treating aging-related diseases in humans (2). It is also well known that coronary heart diseases (3) are low in southern France despite high intake of saturated fat – as a result of red wine consumption. Also, the incidence of cancer is supposed to be low because of resveratrol (C14H12O3) intake. The above materials are found in red wine, in vegetables (3) and peanuts. Nine commercial varieties of tomatoes – including Daniella – were tested in Spain for phenolic compounds, lycopene and antioxidant activity. The phenolic compounds were characterized as flavonoids (quercetin, kaempferol and nargingenin) and hydroxycinnamic acids. The antioxidant activity of tomato extracts varied with the tomato variety and the assay method used (4). The antioxidant activity of tomatoes is discussed and the experimental methods are described. The varieties are unknown in Israel except for Daniella. Commercial cooked tomato paste containing naringenin, one of the most abundant polyphenols in tomato, was tested in Italy for antioxidant activities (5). The research demonstrated, that lycopene with polyphenols enhances antioxidant properties and the results support the hypothesis that tomato benefits could be attributed to a positive synergistic action in vivo between lycopene and other constituents such as naringenin. In a recent, most interesting study on antioxidants in tomato as a function of genotype, 12 tomato varieties were tested (6). Among those varieties phenolic content was highest in the Israeli cherry cv 818, which is a cv. 139 type with added disease resistance, excellent taste and the ripening inhibitor gene nor. The second best was cv. 124 BR cherry also containing the nor long shelf life gene. In this study, phenolic content of the tomato peel was higher than the pulp. Antioxidant activity of genotypes is given in Fig. 3 in paper 3. This research showed the high potential of our cherry varieties, containing high levels of antioxidants. Our conclusions are: There is little doubt that tomato polyphenols and lycopene have beneficial health effects. Our cherry cvs., bred about 20 years ago, are high in polyphenols. The new cherry cvs. 1335 and 1339 bred by Frida – as well as many new genetic types should

be tested for polyphenol content. The results will be important for human health – as well as for large scale marketing of fruits

and seeds

Excellent chromosome maps of markers are available on the SGN web site (www.sgn.cornell.edu), and these genetic maps have RFLP, SSRs, BAC clones, cDNAs, CAPS, ESTs, and COSII markers. The objective of our project was to locate introgressions associated with begomovirus-resistance genes in germplasm from the tomato breeding program at San Carlos University, Guatemala (Mejía et al., 2005). PCR fragments were amplified using primers for markers from the SGN web site, if available, and by designing primers, if not. These PCR fragments were directly sequenced, and the sequence of fragments from begomovirus-resistant inbred lines were compared with each other and the corresponding fragments from susceptible lines. The presence of SNPs or indels in fragments from resistant-inbred lines was assumed to indicate an introgression from a wild species. Germplasm tested: Begomovirus-resistant inbred lines used in this study were part of the tomato breeding program at San Carlos University, Guatemala City (Mejía et al., 2005). The original sources of begomovirus-resistance were hybrids or lines generously provided by colleagues from public institutions. Inbred lines derived from the hybrids (e.g., FAVI-9) provided by F. Vidavsky and H. Czosnek (1988), which had resistance genes introgressed from Solanum habrochaites LA1777 and/or LA0386, are designated G for Guatemala, then h for Hebrew University of Jerusalem (HUJ), and numbers for the cross and the selection, e.g., Gh25-3. The resistance genes in these lines originated from line 902 (Vidavsky and Czosnek, 1988). No introgressions had been detected in line 902 at the time (1998) the germplasm was received in Guatemala. P. Hanson, Asian Vegetable Research and Development Center, Taiwan, provided inbred line, H24, with resistance derived from the Ty-2 locus of S. habrochaites. This line was used solely as the standard for the introgression in chromosome 11 (Hanson et al., 2000, 2006).

Three sources of begomovirus-resistance from S. chilense were obtained. J.W. Scott, University of Florida, provided begomovirus-resistant inbreds, Fla. 595-2 and Fla. 8348, derived from S. chilense LA2779 and LA2779/LA1932, respectively. These Florida inbreds have introgressions on chromosome 6 (Agrama and Scott, 2005; Ji and Scott, 2005, 2006; Ji et al., 2007). The lines Gc9 and Gc171 were selected from Fla. 595-2 and Fla. 8348, respectively. Gc9 was crossed with susceptible hybrids, and resistant-inbred lines were derived from these populations. These selections were designated G for Guatemala, then c for S. chilense, and numbers for the cross and the selection, e.g. Gc143-2. H. Czosnek, HUJ, provided TY52, an inbred with resistance from S. chilense


32

LA1969. This line was used as the standard for the introgression for the Ty-1 locus on chromosome 6 (Zamir et al., 1994). Susceptible germplasm included M82-1-8 (Ve, F1, HUJ), Heinz 1706 (Ve, F1, Heinz Seeds), HUJ-VF (Ve, F1, HUJ), the heritage tomatoes, Purple Russian and German Pink, and the landrace of S. lycopersicum var. cerasiformae (cera), which was collected in Sanarate, Guatemala. Results and Discussion: Primer information, sequence data and marker detection protocols for this report are available at the web site: www.plantpath.wisc.edu/GeminivirusResistantTomatoes/markers.html

For several chromosomes, resistance-gene hot spots were selected as the most likely regions for detecting introgressions (Pan et al., 1999). Eighty-eight markers were evaluated on eight chromosomes. One, nine, two, one, one, and seven markers were amplified and sequenced from chromosomes 1, 2, 4, 7, 9, and 12, respectively. No evidence for introgressions from wild species was detected in begomovirus-resistant germplasm for these markers. For chromosomes 6 and 11, sequence data are reported for 38 and 15 markers, respectively, and introgressions at several markers were detected in the begomovirus-resistant germplasm.

Chromosome 6, which is known to have various resistance genes (Agrama and Scott, 2006; Foolad and Shrama, 2005; Zamir et al., 1994), was studied most extensively. Markers at 5-cM intervals were amplified and sequenced. Gc9 (LA2779) and lines derived from Gc9 had an introgression from LE_HBa0037I09 (5 cM) to T0834 (32 cM). No introgression was detected from the top of the chromosome to T0270 (3.0 cM) or from marker TG365 (33.5 cM) to the bottom of the chromosome 6. Our results support the recent report by Ji et al. (2007) that some LA2779-derived inbreds similar to Gc9 had an introgression from 5.3 to 32 cM, which included the Ty-1 and Ty-3 regions. To determine if Gc9 had the Ty-1 locus, the sequence for the introgression at the Ty-1 locus (TG97, 8.5 cM, Zamir et al., 1994) of Gc9 was found to be identical to that for this region of line TY52 (Ty-1/Ty-1), and a CAPS marker was developed for this locus (Protocol I for Ty-1 locus). A SCAR marker (P6-6-F1/P6-6-R1 primers) was found at 5.5 cM for the S. chilense introgression in TY52 and some Gc9-derived lines, but this marker is not tightly linked to the Ty-1 gene (Protocol II for the Ty-1 locus). For the Ty-3 locus, FLUW25 and P6-25 (25 cM), co-dominant SCAR markers, were developed. Surprisingly, sequences of 17 markers from 6 cM (Mi23) to 32 cM (T0834) from lines derived from 902, which was derived from S. habrochaites (Vidavski and Czosnek, 1998), were identical to those from Gc9. This region included the loci for the Ty-1 and Ty-3 introgressions. One difference between 902-derived lines and Gc9 was that the REX-1 marker (ca. 5 cM) from 902-derived lines had sequences identical to that of the REX-1 marker from lines with the Mi-1.2 gene (introgressed from S. peruvianum) for resistance to root-knot nematode. Conversely, the sequence for the REX-1 marker for Gc9 was identical to that of TY52 (sequence from S. chilense). A co-dominant SCAR marker (Mi23, ca. 6 cM) for the Mi-1.2 gene was evaluated using primers developed by S. Seah and V. Williamson (per. com., University of California-Davis). This Mi23 SCAR marker is tightly linked to the Mi-1.2 gene and can be used as a CAPS marker for the Ty-1 locus in some lines (Protocol III for the Ty-1 locus). In addition, four sets of primers were designed from the REX-1 marker sequences from various wild species, and these could be used as internal control standards (ICON primers) in multiplex PCR.

From this study of the markers for chromosome 6 with Gc9 and 902-derived lines, it is proposed that the order of markers in these lines is REX-1, Mi-1.2, acid phosphatase, Ty-1 and Ty-3. This order is supported by the observation that 902 has the REX-1 marker, but lacks the Mi-1.2 gene. Lines with only the Ty-1 marker (TG97) or the Ty-3 marker (FLUW25) were detected in 902-derived


33

lines, and one line, Gh2, was homozygous for Rex-1, Mi23, Ty-1 (TG97) and Ty-3 (FLUW25) markers. As expected from the marker analysis, this line, Gh2, was resistant to root-knot nematode (bioassay by V. Williamson, Univ. of California-Davis) and also resistant to begomoviruses.

Chromosome 11 is known to have an introgression from S. habrochaites for the Ty-2 gene between TG36 (84 cM) and TG26 (92 cM) (Hanson et al., 2000, 2006). Primers for four markers for this region were evaluated. Primers (T0302F/Ty-2R2) for the T0302 marker amplified different size fragments for susceptible and resistant genotypes (co-dominant T0302-Ty-2 SCAR Marker). Since the I-2 gene (91.5 cM) for resistance to Fusarium oxysporum f. sp. lycopersicum race 2 is closely linked to the Ty-2 locus, it was a concern that the T0302-Ty-2 SCAR marker might give a false positive with I-2/I-2 genotypes. Fortunately, no alien introgression was detected in lines that had the I-2 locus and lacked the Ty-2 locus. No lines with the Ty-2 and I-2 loci were available to test. For many markers, sequence is provided on the web site for various accessions of S. chilense, S. peruvianum, and S. habrochaites, e.g. REX-1, Mi23, FLUW25, T0834, and T0302.

Tomato spotted wilt virus (TSWV) is one of the most damaging pathogens in tomatoes (Solanum lycopersicum L.). In some areas of the world TSWV has become a limiting factor in tomato production (Canady et al., 2001). Several TSWV resistance genes have been identified (Sw1

a, Sw1b,

sw2, sw3, sw4, and Sw-5); however, Sw-5 is the only gene that has been broadly utilized in tomato breeding because of its durability to multiple tospoviruses (Boiteux and Giordano, 1992; Stevens et al, 1992). Additionally, we have tested UPV 32, which has TSWV resistance gene identified as Sw-6 (Roselló et al. 2001), with typical TSWV isolates and were unable identify this resistance in greenhouse screening conditions (Stevens, unpublished data). Although rare, there have been new TSWV isolates identified that overcome Sw-5 (Latham. and Jones, 1998; McMichael et al. 2002). Tospovirus resistance from S. chilense has been identified by Stevens et al. (1994) and introgression from this species has demonstrated to be useful under field conditions (Canady et al., 2001). Furthermore, this germplasm has demonstrated resistance to isolates that overcome Sw-5 (Stevens, unpublished data). In a preliminary study, Scott et al., (2005) reported that resistance was controlled by one or two dominant genes. More recently we concluded that this resistance was conferred by a single dominant gene not linked to Sw-5 (Scott, Olson, and Stevens, unpublished data). This gene will tentatively be referred to as Sw-7. It is essential that linked molecular markers be identified to facilitate the deployment of Sw-7 in coordination with Sw-5. The objective in our BYU lab has been to identify molecular markers linked to this new source of tospovirus resistance. Thirty-seven sister lines putatively containing Sw-7 (developed from F2 and BC1 plants suggesting TSWV resistance) are being used to identify the molecular markers. Eight of these selected F2 and BC1 plants have undergone preliminary P33 AFLP analysis. Candidate markers suggesting linkage to Sw-7 have been tested using all 37 of the above mentioned lines in a second screening using the AFLP LI-COR 4300. Additionally, we have included seven Florida lines isogenic except for Sw-7. These Florida lines have undergone further crossing to elite tomato lines and thus have unique and more advanced genetic backgrounds compared to the lines used in our lab at BYU. Our initial AFLP screenings of eight plants containing resistant/susceptible plants, along with the two parents, were screened with 256 primer combinations. Of the 256 primer combinations 16 resulted in





36

the identification of 30 candidate markers. These 30 putative Sw-7 markers are being examined on our carefully screened 37 F2 and BC1 lines along with the seven field selected Florida lines. One strong candidate AFLP marker has been identified (~200bp) in both the 37 greenhouse selected lines and the seven Florida field selected lines. This candidate marker is currently being prepared to be cloned and sequenced. We are hoping to use this marker to identify where in the tomato genome Sw-7 is located. Additionally, analysis with this marker is currently being conducted on a much larger TSWV resistant population derived from the same germplasm. Furthermore, we are continuing to evaluate the 29 additional AFLP markers identified in our initial marker screening. Several of these markers suggest looser linkage to Sw-7; however, our analyses of the complete set of these markers is incomplete. Development of these markers may allow us to stack Sw-7 with Sw-5 which may allow development of germplasm with broader and more stable resistance to tospoviruses.

Evaluation of a co-dominant SCAR marker for detection of the Mi-1 locus for resistance to root-knot nematode in tomato germplasm Stuart Seah1,4, Valerie M. Williamson1, Brenda E. Garcia2,3, L. Mejía3, Melinda S. Salus2, Christopher T. Martin2, and Douglas P. Maxwell2

Entomology, Private Bag 5, Wembley, WA 6913, Australia Email: [email protected] The Mi-1 resistance gene was introgressed into cultivated tomato from Solanum peruvianum in the 1940’s (Smith, 1944). This gene confers resistance against many isolates of the root-knot nematode species Meloidogyne incognita, M. javanica, and M. arenaria and is currently the only source of root-knot nematode resistance in modern tomato cultivars. The principle means for developing nematode-resistant tomato cultivars is by traditional breeding aided by marker-assisted selection to detect the Mi-1 gene. Co-dominant CAPS markers such as REX-1 (Williamson et al., 1994) and Cor-Mi (Contact Cornell University Foundation, Ithaca, NY) are widely used to assay for the Mi-1 gene in tomato. Although these markers are generally reliable, El Mehrach et al. (2005) found that both gave false positives for nematode resistance with germplasm derived from Ih902 (F1, F2, Ve), which has begomovirus-resistance genes reportedly introgressed from Solanum habrochaites (listed as 902 in Vidavsky and Czosnek, 1998), but is susceptible to root-knot nematode (V. Williamson, unpublished data). Ih902 is one of the main sources of begomovirus resistance in the tomato breeding program at San Carlos University (Mejía et al., 2005), and it is important to have a breeder-friendly marker that does not give false positive results. Therefore primers were designed that amplify a PCR fragment only if the Mi-1.2 gene, the functional gene for resistance (Milligan et al., 1998), is present. However, these primers do not distinguish homozygous and heterozygous plants (El Mehrach et al., 2005). Here we report evaluation of a co-dominant SCAR marker Mi-23 that is tightly linked to the Mi-1.2 gene. Material and Methods Primers: The region on the short arm of chromosome 6 where the Mi-1 locus is located is well characterized genetically and physically (see Seah et al., 2004, 2007). The Mi-1 locus in both resistant and susceptible tomato consists of two clusters with three and four copies of Mi gene homologues, which in resistant tomatoes are separated by approximately 300 kb. Comparison of sequence downstream of Mi-1.2 with a conserved region from susceptible S. lycopersicum led to the development of primers (Mi23F and Mi23R) that flanked an indel within this conserved region (Seah and Williamson, unpublished). The sequence of Mi23F is 5’-TGG AAA AAT GTT GAA TTT CTT TTG-3’, and Mi23R is 5’- GCA TAC TAT ATG GCT TGT TTA CCC-3’. PCR protocol: DNA was extracted from fresh leaves of plants with PUREGENE® DNA Purification Kit (Gentra Systems, Inc., Minneapolis, MN) and DNA adjusted to approximately 10 ng/µl. PCR was carried out in 25-µl reactions containing 2.5 µl 2.5 mM dNTPs, 5 µl 5X buffer, 2.5 µl 2.5 mM MgCl2, 0.1 µl (0.5 units) GoTaq DNA polymerase (Promega Corp., Madison, WI), 2.5 µl each forward and reverse primer at 10 μM, 2-5 µl of DNA extract, and water. PCR cycles were 94 C for 3 min, the 35 cycles of 94 C for 30 sec, 57 C for 1 min, and 72 C for 1 min. These cycles were followed by 72 C


38

for 10 min, and then the reaction was held at 18 C. PCR reactions were performed in the MJ DNA Engine PT200 Thermocycler™ (MJ Research Inc., Waltham, MA). Amplified fragments were separated by electrophoresis through 2% agarose in 0.5X TBE buffer, then stained with ethidium bromide, and visualized with UV light. For sequencing, ssDNA was digested in PCR reactions with shrimp alkaline phosphatase (Promega Corp.) and exonuclease I (Epicentre, Madison, WI), and the PCR fragments were directly sequenced with Big Dye Sequencing Kit™ and analyzed by the Biotechnology Center, University of Wisconsin-Madison. Germplasm: The lines M82-1-8 (Ve, F1) and Gh13 were used as the mi/mi genotypes (susceptible); these lines carried the S. lycopersicum sequence for the REX-1 marker (AY596779). Two lines, Motelle and Gh2, which are known to be homozygous for resistance to root-knot nematode (Mi/Mi genotype) have the S. peruvianum sequence for the REX-1 marker (AY729670). The F1 hybrid, Llanero (resistant to begomoviruses, GenTropic Seeds), which is heterozygous for nematode resistance (Mi/mi) (unpublished data), and Marwa (Ve, F2, N and tolerant to Tomato yellow leaf curl virus, Syngenta), which is presumed to be heterozygous for nematode resistance, were used as heterozygous controls. Other commercial F1 hybrids, which were determined to be heterozygous at the REX-1 locus by sequence analysis, were Celebrity (Seminis Seeds), Charanda (Vilmorin), Crista (Harris Moran), Dominique (Hazera Genetics), Tequila (Vilmorin), and Viva Italia (Harris Moran). Rodeo (Heinz) was homozygous at the Mi locus, as determined by the sequence of the REX-1 marker. Titrit (F1, F2, Ve, TMV, FCRR, Royal Sluis) is susceptible to RKN, but is tolerant to Tomato yellow leaf curl virus. Results and discussion The susceptible genotypes M82-1-8 and Gh13 (mi/mi) and the resistant genotypes Motelle and Gh2 (Mi/Mi) gave PCR fragments of ca. 430 bp, ca. 380 bp (Fig. 1 or not shown), respectively, as expected for susceptible and resistant tomato. The PCR fragments from M82-1-8 and Gh2 were sequenced and a BLAST search performed at the National Center for Biotechnology Information. The 432-bp fragment (AY596779) from M82-1-8 had 100% nt identity with S. lycopersicum (cv. Heinz 1706, DQ863289) for nt 9,545-9,976, which is located between two resistance-like protein ORFs in cluster 2e. The 377-bp fragment from Gh2 had 100% nt identity with the Mi-1 locus from Motelle (AY729670, S. peruvianum introgression for Mi-1 locus) for nt 25,819-26,195 (U81378), which is located between the Mi-1.2 resistance gene and a pseudo-resistance gene (Mi-1.3) in cluster 1p. Thus, the sequence of the PCR fragments matched the areas of the S. lycopersicum and S. peruvianum genomes used to design the primers. When the two sequences were compared, there were indels of 1 nt and 56 nt, which accounted for the differences in the length of the two sequences. Besides these two indels, there were 13 SNPs between these two sequences. The heterozygous genotypes Llanero and Marwa gave three fragments, 380, 430 and 500 bp (Fig. 1), respectively. The third, slower moving PCR fragment from the heterozygous plants was hypothesized to be a heteroduplex between the two fragments (380 and 430 bp), which migrated more slowly due to the presence of a 56 nucleotide loop in the heteroduplex molecules. This hypothesis was supported by mixing approximately equal amounts of the 380 and 430-bp fragments and subjecting this mixture to the normal PCR cycle. Three bands of the same size as those from the heterozygous plant resulted from this treatment (Fig. 1, lane 5). When six commercial hybrids (Celebrity, Charanda, Crista, Dominique, Tequila and Viva Italia) with reported resistance to root-knot nematode were tested with the primers Mi23F/Mi23R, all hybrids had the three-banded pattern associated with heterozygous plants for the Mi-1 locus; and Rodeo gave the expected single 380-bp fragment for the homozygous genotype (Mi/Mi). Titrit, which lacked the Mi-1 locus gave the 430-bp


39

fragment corresponding to that associated with the susceptible allele. The Mi23 primers were also tested on 73 breeding lines and hybrids for begomovirus resistance from the tomato breeding project at San Carlos University, Guatemala (Mejía et al., 2005), as well as on 31 other inbreds and hybrids, and unambiguous PCR patterns were obtained. Previously false positive results for the Mi-1 locus (nematode resistance) were obtained with two co-dominant CAPS markers, REX-1 and Cor-Mi, for the begomovirus-resistant breeding line, Ih902 (El Mehrach et al., 2005). The begomovirus-resistance Ty-1 locus is derived from Solanum chilense LA1969 and was mapped to the short arm of chromosome 6 (Zamir et al., 1994). The REX-1 marker for the TY52 line, which is homozygous for Ty-1/Ty-1 (H. Czosnek, pers. com.), gives a distinct digestion pattern with TaqI restriction enzyme (three fragments, Milo, 2001). Thus, it was of value to test primers Mi23F/Mi23R with tomato lines that gave false positive REX-1 and Cor-Mi restriction digestion patterns, as well as lines known to have the S. chilense introgression for the Ty-1 locus. When Ih902, TY52, and 2 breeding lines (Gc9 and Gc143-2) with the Ty-1 locus were evaluated with the Mi23F/Mi23R primers, only one PCR fragment of 430 bp was obtained. This fragment size was approximately the same as in nematode-susceptible S. lycopersicum, and, thus, the fragment size correlated with the nematode susceptible phenotype of these lines. Sequences of PCR-fragments (EU033925) from the 4 lines were identical, and there were 16 SNPs and a 1-nt indel between this sequence and the sequence from susceptible S. lycopersicum (e.g., M82-1-8). These results indicate that primers Mi23F/R should be adaptable for detecting genotypes with the Ty-1 locus introgressed from S. chilense. This co-dominant SCAR marker has the advantage over previous PCR-based markers in that restriction enzyme digestion of the amplified product is not required, and it does not give false positive fragments with the begomovirus-resistant breeding lines derived from S. habrochaites (Vidavsky and Czosnek, 1998) and S. chilense (Ty-1 locus) (Agrama and Scott, 2006). Additionally, Mi23 may be useful for tomato breeders introgressing other traits located in the resistance gene cluster on the short arm of chromosome 6.

Transgenic Lycopersicon ssp. plants expressing the gene for human acidic fibroblast growth factor Petya Stoykova*, Mariana Radkova*, Pravda Stoeva-Popova**, Xingzhi Wang***, Atanas Atanassov* *Agrobioinstitute, 8 Dragan Tsankov blvd., 1164 Sofia, Bulgaria **Winthrop University, Rock Hill, SC 29733, USA ***Institute of Genetics and Cytology, Northeast Normal University, Changchung, China In the past decades, genetic transformation of plants has become a rapidly expanding area with increasing commercial application of the end product. Plants as bioreactors of pharmaceutical proteins are safer in comparison to microorganisms,animals, and animal tissues because of the lack of human pathogens- prions, oncogenic DNA sequences and endotoxins (Commandeur et al., 2003, Stoger et al., 2002; Schillberg et al., 2002). In this work we report the transformation of Lycopersicon esculentum cv. Bela and the wild species L. pennellii with the gene for human acidic fibroblast growth factor (haFGF, FGF-1) and phosphomannose isomerase as a selectable marker gene. Phosphomannose isomerase (PMI) (EC 5.3.1.8) is an enzyme that is common in nature, but is less widespread in the plant kingdom. PMI catalyzes the reversible conversion of mannose-6-phosphate into fructose-6-phosphate. The gene for PMI is an appropriate selectable marker gene for positive selection of transgenic plants because plants expressing the PMI gene can assimilate the monosaccharide mannose (Joersbo et al., 1998). FGF-1 is a small nonglycosilated molecule of 17 kDa with a cytokine character that binds in a dimeric shape for excretion from the cell. It takes part in the processes of formation and migration of endothelial and smooth muscle cells which are used in therapeutic angiogenesis. The new lymph vessel growth, as well as recovery of injured ischemic blood vessels, is increased when using such therapy (Iwakura, 2001). FGF-1 is used in skin wound and burn healing (Mellin et al., 1992), as well as pressure ulcer healing (Feldman, 1994). For this study as plant material for genetic transformation we used cotyledon explants from in vitro grown 8 -10 day-old seedlings from the tomato cultivar Bela and the green-fruited species L. pennellii. The genetic transformation experiments were carried out with Agrobacterium tumefaciens strain LBA4404 supplemented with a constitutive virG mutant gene on a compatible plasmid for very efficient T-DNA transfer (Van der Fits et al., 2000). The strain carried the binary vector pM390haFGF harbouring manA gene and a cDNA of the hafgf gene both under the CaMV 35S promotor. The procedure for co-cultivation, and selection of transgenic plants followed the protocol of Sigareva et al. (2004). The following media were applied: co-cultivation medium - ½ MS salts and vitamins, 0.5 mg/L BAP, 20 g/L sucrose, 10 g/L glucose and 8 g/L agar; selection medium (for the first six weeks of development) – MS salts and vitamins, 1 mg/L zeatin, 0.01 mg/L IAA, 5 g/L glucose, 10 g/L mannose, 500 mg/L cefotaxim, and 8 g/L agar; selection medium for shoot elongation – MS salts and vitamins, 1 mg/L zeatin, 1 g/L glucose, 10 g/L mannose, 500 mg/L cefotaxim and 8 g/L agar; rooting medium – MS salts and vitamins, 10 g/L sucrose, 5 g/L mannose, 300 mg/L cefotaxim. T0 shoots that rooted on mannose-containing medium were further analyzed. To determine the presence of the transgenes, plant genomic DNA was extracted according to the protocol of Murray and Thompson (1980) and the polymerase chain reaction (PCR) was carried out with specific primers for hafgf and manA genes (data for the manA gene not shown). Primers for the hafgf gene were 5’ GGTACCATGGCTAATTACAAGAAGC 3’ (forward) and 5’ GAGCTCTTAATCAGAAGAGACTGGCA 3’ (reverse). PCR was performed in a thermal cycler using the following conditions: 1 cycle for 5 minutes at 940C; 35 cycles each of 30 seconds at 940C, 30 seconds at 580C and 30 seconds at 720C, followed by a final extension at 720C for 7 min. The amplification product for the hafgf gene was a


42

fragment of the expected size of 423 bp, as revealed by agarose gel electrophoresis. The amplification product for the hafgf gene was established respectively in four regenerants from cv. Bela and in three regenerants from L. pennellii that were cultivated and rooted in the presence of mannose (Fig.1, Fig.2). Six of the seven regenerants were successfully micropropagated and adapted under controlled conditions in the greenhouse. To determine the expression of the hafgf transgene, we extracted total soluble protein from leaves of PCR positive and control plants. Indirect ELISA was performed using monoclonal mouse anti-haFGF antibody. The reaction was visualized with anti-mouse antibody conjugated to HRP (horseradish peroxidase) and OPD (o-phenylenediamine) was used as a substrate. The reaction was stopped with H2SO4 and the reaction was measured at OD 495nm on an ELISA reader. The analysis determined the expression of the haFGF protein in four of the seven analyzed T0 transgenic plants (Fig.3). All T0 plants were fertile (Fig.4); they were self-pollinated and produced viable seeds. Further studies are underway to analyze the expression of the hafgf transgene in the next generation.

Revised List of Wild Species Stocks

Chetelat, R. T. C.M. Rick Tomato Genetics Resource Ctr., Department of Plant Sciences, University of California, One Shields Ave., Davis, CA 95616 The following list of 1,190 accessions of wild Lycopersicon and related Solanum species is a revision of the previous one, published in TGC vol. 54 (2004). Other types of TGRC stocks are catalogued in TGC 55 (monogenic mutants) and TGC 56 (miscellaneuous genetic stocks). Inactive accessions have been dropped and new collections added to the present list. The new material includes populations of L. chilense, L. peruvianum, S. lycopersicoides, and S. sitiens collected in N. Chile in 2005 (see TGC 56:13), as well as a L. peruvianum donated by John Rick and L. esculentum var. cerasiforme donated by Lori Pacuilla. Species are identified by both their Lycopersicon and Solanum names in the following tables. Accessions of L. peruvianum recognized by Peralta et al. (2005, Syst. Bot. 30: 424-434) as S. arcanum or S. huaylasense are indicated by superscripts after the accession numbers. Accessions that form part of the core collection are identified by an asterisk. Seed samples of most accessions are available for distribution, upon request, for valid research purposes. Some accessions may be temporarily unavailable for distribution during regeneration, and not all accessions are available for international distribution due to requirements for obtaining phytosanitary certificates. Only small quantities of seed can be provided for each accession, in most cases 25 seed per accession of the self-pollinated species, 50 for the outcrossers, and 5-10 for S. lycopersicoides, S. juglandifolium, S. ochranthum, and S. sitiens. These samples are intended to enable researchers to multiply seed to meet their own future needs. Accessions are grown for seed increase at UC-Davis, either in the field, for most of the selfing species, or in the greenhouse for the outcrossers. Accessions of the former are increased in small plots with as few as 6 plants, whereas the latter are regenerated from relatively large populations (up to 50 plants) to maintain genetic variation. For lack of space, only summary information on the collection site of each is presented here. More detailed information on each accession, including current availability, can be obtained at http://tgrc.ucdavis.edu. Geographic coordinates (lat/lon) have been detemined for most accessions collected from mainland S. America, and can be downloaded in several formats. Hundreds of images of wild populations taken in their native habitats have been added to our database. Additional information will be provided upon request.
