Question

What are cry proteins?

Answer 1

Cry protein is a toxic protein coded by the cry gene. There are many types of cry proteins; for example, the proteins coded by the genes cryIAc and cryIIAb control cotton budworm, while cryIAb controls corn borer.

Answer 2

Bacillus thuringiensis secretes harmful proteins known as insecticidal proteins in the form of cry proteins during a certain growth step. Cry, a gene, codes for the toxin. B. thuringiensis cry protein-encoding genes, often known as Bt toxin genes, have been identified and inserted into numerous crop plants, including Bt cotton, Bt corn, etc., to give insect pest resistance.
