2. Outline  History  Background  Pros  Cons  Economics  Regulations  Questions?

3. History  1983 – First genetically engineered plant developed, a antibiotic resistant tobacco  1991 – US Dept. of Ag. publishes guidelines for genetically engineered crops  1994 – First genetically engineered tomato, Flavr Savr, is introduced into US markets  1995 – Genetically Engineered soybean, corn, and cotton are approved for commercialization  2000 – Golden rice becomes the first food produced that was genetically modified to increase nutritional value

4. Background  Genetic Engineering has allowed the exchange of genetic material between living species  A genetically modified organism is an organism whose genome has been altered by addition or subtraction of a specific gene  Inserted genes come from external, unrelated sources

5. Genetically Engineered Crops  Examples of common genetically modified crops  Alfalfa  Corn  Cotton  Papaya  Rice  Soybeans

6. Techniques  Agrobacterium  Biolistic Transformation  Electroporation  Microinjection  Antisense Technology

7. Benefits of Genetically Modified Crops  Increased resistance against pests, herbicides, and diseases  Reduced herbicide and pesticide use (?)

8. Benefits of Genetically Modified Crops  Higher environmental tolerance  Possibility to increase efficiency of plant food production

9. Benefits of Genetically Modified Crops  Improve food quality  Increase nutritional content

10. Cons of Genetically Modified Crops  Emergence of new diseases  Allergens

11. Cons of Genetically Modified Crops  Resistance  Increased pesticide and herbicide use (?)

12. Cons of Genetically Modified Crops  Non-GE crops contaminated  Lack of long-term research

13. Economics

14. US Regulations  Three agencies are responsible for genetically modified crops  FDA  USDA  EPA  Federal Food, Drug and Cosmetic Act (FFDCA)  Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)  Genetically modified food labelling is optional in the United States
