– These technologies involve introducing genes from the bacterium *Bacillus thuringiensis* (Bt) into the cotton plant’s genome.
– The Bt genes (specifically *cry1Ac* in Bollgard I and *cry1Ac* and *cry2Ab* in Bollgard II) produce proteins that are toxic to certain insect pests, particularly the cotton bollworm (Helicoverpa armigera) and other lepidopteran pests.
– This genetic modification makes the cotton plant resistant to these pests, reducing the need for chemical insecticides and improving yields. This is a classic example of genetic modification for pest resistance in crops.
