Q1. The American multinational company, Monsanto, has produced an insect-resistant cotton variety that is undergoing field trials in India. A toxic gene from which one of the following bacteria has been transferred to this transgenic cotton?
Explanation
Monsanto, an American multinational company, developed an insect-resistant cotton variety known as Bt cotton. This transgenic cotton incorporates a gene from the bacterium Bacillus thuringiensis (Bt), enabling the plant to produce Bt toxins that are effective against specific insect pests, particularly lepidopteran larvae like the cotton bollworm. The introduction of the Bt gene allows the cotton to produce its own insecticide, reducing the need for external chemical insecticides.
