Bacillus thuringiensis accumulates, primarily during sporulation, large quantities of insecticidal protoxins which are deposited as crystalline, intracellular inclusions. Most subspecies contain several plasmid-encoded cry genes, each of which has a unique specificity. The overall toxicity profile of a subspecies depends not only on the array of cry genes… CONTINUE READING
