Which crop is commonly recognized as being genetically modified for pest resistance?

• A. Bt cotton
• B. Organic wheat
• C. Traditional rice
• D. Heirloom tomatoes

Answer: (A)

Bt cotton is widely recognized for its genetic modification aimed at providing pest resistance. This crop has been engineered to express a protein from the bacterium Bacillus thuringiensis (Bt), which is toxic to certain insect pests, particularly the cotton bollworm. By incorporating the Bt gene, cotton plants can produce this naturally occurring insecticide throughout their tissues, thereby reducing reliance on chemical pesticides and improving cotton yield quality and quantity. The genetic modification of Bt cotton exemplifies a significant advancement in agricultural biotechnology, facilitating more sustainable farming practices by targeting pests specifically and minimizing environmental impacts associated with conventional pesticide use. This technology helps farmers achieve better control over pest infestations, leading to enhanced crop productivity and profitability. In contrast, the other options listed—such as organic wheat, traditional rice, and heirloom tomatoes—do not involve genetic modification for pest resistance. Organic farming typically prohibits the use of genetically modified organisms (GMOs), while traditional rice and heirloom tomatoes represent cultivars that have been developed through conventional breeding methods or maintained through traditional agricultural practices without genetic engineering.
