• Green Biotechnology


  Biotechnology applied in agriculture
• GM Crops


  Engineered crops marketed by farmers due to altered DNA
• BT Corns (Bacillus thuringiensis corns)


  • Genetically modified corn
  • Inserted a toxic gene from Bacillus thuringiensis
  • Increase in production was realized because of its resistance to the attack of the corn borer
• BT Cottons (Bacillus thuringiensis cottons)


  • Genetically modified cotton
  • Inserted a toxic gene from Bacillus thuringiensis
  • Increase in production of cotton (to create cottonseed oil and textiles)
  • Resistance to the attack of bollworms
• GM Potato


  • Genetically modified potato
  • Inserted a gene from Snowdrop Flower
  • To resist bruising and browning when packaged, stored, transported, or cut in the kitchen
  • Resist INSECTS
  • To improve nutritional value
• Golden Rice


  • Genetically Modified Rice
  • Inserted a gene from Daffodil
  • Infused beta-carotene 20x better than regular rice
  • High levels of Vitamin A
  • Combats malnutrition, especially children with low levels of Vitamin A
• GM Papaya


  • Genetically Modified Papaya
  • Inserted a protein from the Papaya Ringspot Virus to make the Papaya immune from the Virus itself

  
• GM Peas


  • Genetically Modified Peas
  • Inserted a protein from kidney beans to free the peas from pests
• GM Canola


  • Genetically Modified Canola
  • Inserted a gene from agrobacterium – bacteria found in soils to improve food consistency and prolong shelf life
• Flvr Savr Tomato


  • Genetically Modified Tomato
  • Designed to withstand the rigors of shipping, one that would last for weeks while regular tomatoes shriveled and rot
  • Inserted a gene from agrobacterium – bacteria found in soils to improve food consistency and prolong shelf life
• Advantages of GM Crops

  • Tolerant to stresses such as drought, cold, and heat
  • Pest-resistant
  • Reduce post-harvest costs and losses to farmers
  • Enhances nutritional value
• Disadvantages of GM Crops

  • Unintentionally introducing allergens and other antinutritional factors into foods
  • Escaped transgenes affecting other organisms
  • Evolution of pest resistance to the toxic gene
  • Affects other unintended organisms with its genetic makeup
