Bt cotton variety that was developed by the introduction of toxin gene of Bacillus thuringiensis (Bt) is resistant to

Step-by-step solution

Bt toxin is produced by Bacillus thuringiensis has been cloned in bacteria and been expressed in plants to provide resistance to insects without the need for insecticides in effect creating a biopesticide. Examples are Bt cotton, corn, rice, tomato, potato, soybean, etc. Specific Bt toxin genes were isolated from Bacillus thuringiensis and incorporated into several crop plants such as cotton. The choice of a gene depends on the crop and the pest as most Bt toxins are insect group-specific. This toxin is encoded by
