Introduction and Historical Review of Biotechnology
Michael D. Peel
NDSU
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

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

What do all these terms mean
Questions to consider
• How does biotechnology affect me?
• How will biotechnology affect my children?
Program outline
AM• Understanding biotechnology
PM• Current status of transgenic crops• Biotech products and health issues• Regulation• Breakout sessions
