Applications Functions/Example Bt cotton Bt toxin as 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 created a bio-pesticide. Examples are Bt cotton, corn, rice, tomato, potato and soyabean etc. Adenosine deaminase deficiency The first gene therapy was done in a four year old girl suffering from the disorder called SCID that arises due to deficiency of Adenosine deaminase (ADA) deficiency.
