Characterization of genes from Bacillus thuringiensis israelensis encoding toxins with different specificities towards mosquito larvae



Characterization of genes from Bacillus thuringiensis israelensis encoding toxins with different specificities towards mosquito larvae



Israel Journal of Entomology 1990; 23: 213-217



Biochemical analysis and cloning experiments by different groups indicate that B. thuringiensis subsp. israelensis crystals contain at least 4 main proteins of 28, 68, 125 and 135 kDa. Results on the biocidal activity of each of these polypeptides are sometimes contradictory. Synergistic activity between several combinations of different proteins has been proposed. The genes coding for the B. t. israelensis crystal proteins are located on a resident plasmid of 72 MDa.
