Explain the purpose of herbicide tolerance in transgenic crops and provide an example of a widely used herbicide-tolerant crop.
Explain the purpose of herbicide tolerance in transgenic crops and provide an example of a widely used herbicide-tolerant crop.
Herbicide tolerance in transgenic crops allows them to survive the application of specific herbicides that would normally kill the non-modified version of the crop. This trait enables farmers to control weeds more effectively without harming the crop. An example of a widely used herbicide-tolerant crop is glyphosate-tolerant crops such as soybeans, corn, and cotton.
What is the purpose of insect resistance in transgenic crops?
What is the purpose of insect resistance in transgenic crops?
Insect-resistant transgenic crops produce proteins toxic to certain insects, which helps reduce the damage caused by insect pests.
What are some common traits introduced into transgenic crops to improve their performance and yield?
What are some common traits introduced into transgenic crops to improve their performance and yield?
Common traits introduced into transgenic crops to improve their performance and yield include herbicide tolerance, insect resistance, and disease resistance.

Study Notes
Herbicide Tolerance in Transgenic Crops
- Purpose: allows farmers to use specific herbicides to control weeds without damaging their transgenic crops, reducing competition for water and nutrients.
- Example: Roundup Ready soybeans, engineered to be tolerant to the herbicide glyphosate (Roundup), widely used in the US.
Insect Resistance in Transgenic Crops
- Purpose: protects crops from damage caused by insects, reducing pesticide use and increasing crop yields.
Improving Crop Performance and Yield
- Introduced traits:
- Insect resistance
- Herbicide tolerance
- Drought tolerance
- Salt tolerance
- Improved nutritional content
- Goals: increase crop yields, improve crop quality, and reduce pesticide and water usage.
Benefits for Farmers
- Simplified weed management: herbicide-tolerant crops enable effective weed control with reduced labor and equipment use.
- Increased crop yields: reduced competition from weeds and insects leads to higher yields and improved profits.
- Reduced pesticide use: insect-resistant crops reduce the need for pesticides, minimizing environmental impact.
