Study Notes

Agricultural Biotechnology

Agricultural biotechnology involves using scientific techniques to modify and improve plants and microorganisms for farming purposes.
It utilizes molecular biology to improve agricultural practices, address challenges like abiotic and biotic stress, and enhance crop productivity.

Key Aspects

Genetic Modification: This involves altering an organism's DNA by inserting, deleting, or modifying genes.
Crop Improvement: Genetic engineering leads to crops with specific traits like pest resistance, disease tolerance, improved nutrition, and higher yields.
Microbial Biotechnology: This involves the development of beneficial microorganisms to enhance soil fertility and improve plant growth.
Plant Tissue Culture: This technique allows for the propagation of plants in a controlled environment, producing disease-free and genetically identical plants.
Molecular Breeding: Using molecular markers and genetic techniques, this process helps identify and select desirable plant traits for developing new crop varieties.

Adoption of Genetically Modified Crops

Genetically modified (GM) crops have specific traits engineered into their DNA.
These traits can include insect resistance, herbicide tolerance, or improved nutritional content.
The adoption of GM crops is steadily increasing worldwide.

Adoption of GM Crops in the United States

The US has a significant adoption of GM crops.
Approximately 94% of soybeans, 92% of maize (corn), and 96% of cotton are genetically modified.

Adoption of GM Crops in South Africa

South Africa also embraces GM crops.
About 94% of maize, 95% of soybeans, and all cotton are genetically modified.

Impact on Global Food Security

GM crops enhance global food security through:
- Increased crop yields leading to more abundant and affordable food.
- Enhanced nutritional content helping to address malnutrition.

Impact on the Environment - Insect Resistance

GM crops with insect resistance can reduce reliance on chemical insecticides.
This leads to less active ingredient usage, improving the environment.
GM crops with herbicide tolerance can benefit the environment.
They allow for more efficient weed control by using less harmful herbicides.
