...-toxic Bacillus thuringiensis products, but not to Cry1Aa and Cry3A, which are not toxic to Cf1 cells. In the presence of extracellular Ca 2+ , the toxin-induced Ca 2+ response was insensitive to methoxyverapamil, a voltage-dependent Ca 2+ channel blocker, but was abolished by lanthanum, a general...
