2 Acreage of GMO Varieties

4 Classical Plant Breeding : Genetic modification following introduction of large amounts of undefined DNA from a genetically similar source. Plant Biotechnology : Genetic modification of a plant cell by introduction of defined DNA(s) from a genetically different source.

5 Biotechnology : Bio = Biology Technology = Application “The application of Biology” (for the benefit of humans) Bio = Biology Technology = Application “The application of Biology” (for the benefit of humans)

6 Plant Biotechnology : 1) Plant Tissue Culture (Cloning) 2) DNA introduction (Gene Transfer) Plant Biotechnology : 1) Plant Tissue Culture (Cloning) 2) DNA introduction (Gene Transfer)

7 Oranges? Strawberries? Potatoes? Apples? Daffodils? Cloning Have you ever eaten/used cloned plants? Turfgrass? Roses? in Plants

8 Cotton Poplar Xmas Cactus Fern Soybean Ohio Buckeye

9 Gene Identification : Genomics Proteomics Metabolomics Herbicide resistance Insect resistance Grain quality Neutrative Virus resistance Growth habit Fungal resistance stress resistance Value added Animal viral vaccines Protein and Oil Pharmaceuticals Flower color

10 Plant Transformation Agrobacterium Particle gun

11 First biotech plant product – Flav’r Sav’r tomato

12 Bt Corn Reduces : Insecticide Mycotoxin Application Production

13 X Monarch larvae on Butterfly weed

14 Public Support Varies for Different Applications of Biotechnology (Includes ALL Countries – N = 35,000) Source: Thomas Hoban, North Carolina State University

15 The Benefits of Using Biotechnology are Greater than the Risks (35,000 Consumers from 35 Countries)

16 The Benefits of Using Biotechnology are Greater than the Risks (European Consumers)

17 Willing to Buy GM Food if More Nutritious (Net = Continue – Not Continue)

18 “ Can you think of any information not currently included on food labels that you would like to see?”

19 Perceptions of safety improved when US consumers learn that biotech foods have been in the stores. Do you think genetically modified foods are basically safe, basically unsafe, or don’t you have an opinion on this? Now, as you know, more than half of products in the grocery store are produced using some form of biotechnology or genetic modification. Knowing this, do you think genetically modified foods are basically safe, basically unsafe, or don’t you have an opinion on this? January 2001 Source: Pew Initiative on Food and Biotechnology
