Question

Quizplus · Accepted Answer

Bt toxin production by soybeans is an example of an insect-resistant plant. Bt (Bacillus thuringiensis) toxin is a naturally occurring bacterium that produces proteins harmful to certain insects. When the genes responsible for Bt toxin production are inserted into a plant's genome, the plant becomes resistant to those insects.
