Biology

• Bacillus thuringients


  • Some strains produce proteins that kill insects like coleopterans (beetles), lepidopterans (tobacco budworm, army worm) & dipterans (flies, mosquitoes)
  • Forms a toxic crystalline insecticidal protein (Bt toxin) during a particular phase of their growth
  • Does not kill the Bacillus as it exists as inactive protoxins
• How is agricultural genetic molecular biotechnology used?

  • Genetic engineering
  • Molecular markers
  • Vaccine
  • Tissue culture
• Types of agriculture

  • Agro-chemical based agriculture
  • Organic agriculture
  • Genetically engineered crop-based agriculture
• Genetically Modified Organisms (GMOs)


  Organisms like plants, bacteria, fungi & animals that are altered by genetic manipulation
• Genetically Modified Crops (GMCs)

  • Bt cotton
• Plant agriculture : Any plant, or part thereof grown, maintained, or used for:

  a. commercial purposes

  b. growing

  c. maintaining

  d. producing plants for sole or research purposes

  e. experimental use

  f. another purpose entirely
• Agricultural Biotechnology


  The application of biological science and technology to agriculture
• Agriculture


  The science, art, and business of cultivating the soil, producing crops, and raising livestock
• Horticulture


  The branch of plant agriculture dealing with crops, generally fruits, vegetables, and ornamental plants
• Horticulture


  • Covers all forms of garden management, in terms of scale it falls between ordinary gardening and field agriculture
• Animal Agriculture


  The domestic focus on breeding animals for the production of products and for recreational purposes
• Animal Agriculture


  • Contributes not only meat, but also other products such as high quality food, fertilizer, and power
• Animal Agriculture provides economic diversification and risk distribution on-farm
