Global challenges—population, food, and land • World population expected to reach 8 billion by 2025*
− 20% of the world’s population is not receiving the minimum food required for a healthy life
− Global demand for food will increase three times in the next 15 years
− Pests destroy 1/3 of the food produced globally ($30 billion spent on pesticides)
− 1.2 billion people globally exist in poverty, with earnings < $1/day
• Recent notable climate events− Increase in intensity of natural disasters and extreme weather events
− Rising sea levels, contamination of water and agricultural land
− Changes in rainfall patterns and water shortage
> Hotter climates contributed to lower wheat (–5.5%) and corn (–3.8%) yields**

Plant Resequencing & SNP Genotyping
22 6/28/2012 | Life Technologies™ Corporation
Plant genotyping and SNP discovery
• SNP (single nucleotide polymorphism): A small variation in DNA sequences of a genome. These variations can be used to track inheritance in families or species.
• Plant SNP discovery: discover SNPs associated with desired traits to improve or enhance certain characteristics such as higher yield or better stress tolerance.
• SNP discovery and trait association study strategies− SNP microarray arrays: identify informative SNPs in a collection of known SNPs
− Targeted resequencing: discover known SNPs and identify informative SNPs

sorghum, and even in wheat’s predecessor, Aegilops tauschii
• GBS using next-generation sequencing technologies is becoming increasingly important:
• It is cost-effective
• It offers utility with complex genomes and those without a reference sequence
• GBS is a good approach for:
• Marker discovery
• Linkage mapping of QTL in a biparental cross
• Fine-mapping QTL
• Bulked segregant analysis (BSA)
• Genome-wide association studies (GWAS)
• NAM-GWAS
• Improving reference genome assembly
26 6/28/2012 | Life Technologies™ Corporation
Advantages of genotyping by sequencing
• Faster, simpler protocol than traditional restriction-site-associated DNA (RAD) method or full de novo sequencing
• Allows de novo marker (SNP) discovery, even in the absence of a reference genome
• High accuracy of SNP calling
• Low cost
• Low amounts of input DNA needed
• Simplified computational analysis
27 6/28/2012 | Life Technologies™ Corporation
Genotyping by Sequencing Strategies and Workflows
• For unknown SNPs (discovery): restriction enzyme digestion is employed to reduce complexity
• Known SNPs (screening): multiplexing PCR primers are designed and barcoded to screen hundreds of SNPs in one sequencing run

GBS on Ion PGM™ Sequencer: a case study on barley
• Drs. Nils Stein (IPK, Germany) and Jesse Poland (USDA-ARS2, Manhattan, KS, USA) partnered with Life Technologies to develop a protocol for GBS in barley using two restriction enzymes
• The challenge: large, complex genome without complete sequence available to date (~5.5 Gb, diploid)
• The goal: develop barley plants with improved traits (e.g., drought tolerance, higher yield)
− Discovery of high-density molecular markers is required for better understanding of genetics of complex traits for breeding
− Approach: genome-wide association (GWAS) studies and genomic selection
29 6/28/2012 | Life Technologies™ Corporation
GBS approach for barley: RE and Ion PGM™ Sequencer• Restriction enzyme digestion of the genomic DNA to reduce complexity
− GBS targets the genomic sequence flanking restriction enzyme sites
• GBS is similar to RAD (restriction-site associated DNA) tagging but has greatly simplified library construction that:
− Requires less DNA and avoids random shearing
− Is completed in two steps followed by PCR of the pooled library
• For barley, the original GBS protocol [1] was extended to a two-restriction-enzyme approach [2]
• Completed a GBS feasibility study using the Ion PGM™ Sequencer
