Study Notes

Applications of Biotechnology in Agriculture

Biotechnology in agriculture involves scientific techniques such as genetically modified organisms, Bt cotton, and pest-resistant plants to modify plants, animals, and microorganisms, improving their agricultural productivity.
Transgenic crops are developed by placing genes into plants to give them a beneficial trait, resulting in:
- Improved yield from crops
- Reduced vulnerability of crops to environmental stresses
- Increased nutritional qualities of food crops
- Improved taste, texture, or appearance of food
- Reduced dependence on fertilizers, pesticides, and other agrochemicals
- Production of vaccines

Bt Corn and BT Cotton

Bt Corn was genetically modified with the insertion of toxin gene from the bacterium Bacillus thuringiensis, making it resistant to the corn borer.
Commercialization of Bt Corn led to an increase in production.
BT Cotton, which accounts for half of the cotton grown worldwide, was genetically modified to resist pests and pesticides.
GMO cotton provides a reliable source of cotton for the textile industry and is used to make cottonseed oil, used in packaged foods and restaurants for frying.

Genetically Modified Organisms

Genetically modified organisms (GMOs) are organisms with foreign genes incorporated into their genome.
Examples of GMOs include Bt Corn and BT Cotton.

Recombinant DNA Technology

This module is designed to help learners master the steps in Recombinant DNA Technology, which is used to create genetically modified organisms.
The module covers the application of biotechnology in agriculture, including the characteristics of genetically modified crops, their advantages and disadvantages, and their importance in the field of agriculture.
