    1. Lecture 13 Chapter 8 Genes and traits of interest II Neal Stewart

    3. Insect resistance

    4. Controlling Colorado potato beetle is not easy

    5. Bt corn

    6. Bt cotton

    8. Bacillus thuringiensis

    9. Bt Cry structure

    13. Different Bt Crys Cry 1s—kills caterpillars (lepidoptera) Cry 2s—kills caterpillars (lepidoptera) Cry 3s—kills beetles (coleoptera)

    14. Transgenic disease resistance Viruses (yes) Bacteria (no) Fungi (no) Nematodes (no)

    17. Discussion question Other than the products discussed in this chapter, what other sorts of genes or strategies might be useful in engineering transgenic plants resistant to insects or pathogens?

    20. Second generation Output traits

    21. Improved nutrition, better foods Golden rice Modified oils from oilseeds Vitamin E enhancements

    22. Golden rice: producing provitamin A

    23. Biotechnologist of the day: Ingo Potrykus

    26. Third generation Non-traditional products

    27. Examples Pharmaceuticals Oral vaccines Phytoremediation Phytosensors Biofuels

    28. Plant-made pharmaceuticals aka Molecular pharming

    30. Phytorediation example How to remediate mercury in soil

    31. Phytosensor example: plants to detect landmines

    33. So, transgenic plants could be used in a lot of applications… Are there any we should avoid?
