Cryprotein (crystal protein) is a toxin coded by a gene cry and is poisonous to some insects. Thus, provide resistance to the plants against insects. Bacillus thuringiensis produces cry protein. Cry protein producing gene is transferred to the plant to provide resistance against insect larvae. Man has developed several transgenic crops by introducing these genes from bacteria to crop plants such as Bt cotton, Bt corn, etc.
What are Cry proteins? Name an organism that produces it. How has man exploited this protein to his benefit?
