How Bt cotton crops are developed?

1.	How Bt cotton crops are developed?
Answer» Bt cotton is a genetically modified organism (GMO) or genetically modified pest resistant plant cotton variety, which produces an insecticide activity to bollworm. Strains of the bacterium Bacillus thuringiensis produce over 200 different Bt toxins, each harmful to different insects. Most Bt toxins are insecticidal to the larvae of moths and butterflies, beetles, cotton bollworms and gatflies but are harmless to other forms of life.The genes are encoded for toxic crystals in the Cry group of endotoxin . When insects attack and eat the cotton plant the Cry toxins are dissolved in the insect’s stomach.The epithelial membranes of the gut block certain vital nutrients thereby sufficient regulation of potassium ions are lost in the insects and results in the death of epithelial cells in the intestine .membrane which leads to the death of the larvae.
