Introduction and Historical Review of Biotechnology
Michael D. PeelNDSU
Recent history of transgenic crops• Relative importance
– Farm community– Public
• Non crop applications of biotechnology to think about
Transgenic crops test by year in the US
Testing of transgenic crops since 1987

Production of Transgenic crops in the US
• Major crops approved– Corn– Soybean– Cotton
• Other approved crops– Tomato– Potato– Sugar beet– Canola– Rice– Plus others

Question?What are the benefits of
biotechnology?
Benefits of Bt• Corn
– Reduced insecticide use– Reduced lodging– Increased yield
• Cotton– Reduced use of
insecticides– Harvestable crop
Benefits to humans• Molecular based diagnosis
– Breast cancer– Parkinson's disease– Hemochromotosis– Genetic diseases in general
• Forensic– Crime– Identification of remains
• Improve nutrition– Yellow rice– Tomatoes high in lycopene, an antioxidant– Higher starch potato, adsorbs less fat when fried
We are seeing it in the Media• PBS Frontline Xenotransplantation (3-27)
– Parkinson's, injection of fetal pig neuro cells into brain
– Liver failure, liver from a transgenic pig use until human liver available
• 60 Minutes II, (3-13)– Transgenic Salmon
