S. Poncet et al., ROLE OF THE CRYIVD POLYPEPTIDE IN THE OVERALL TOXICITY OF BACILLUS-THURINGIENSIS SUBSP ISRAELENSIS, Applied and environmental microbiology, 59(11), 1993, pp. 3928-3930
The gene encoding the CryIVD protein of B. thuringiensis subsp. israel
ensis crystals was disrupted by in vivo recombination. The toxicity of
the CryIVD protein-free inclusions was similar to that of the wild-ty
pe crystals on Anopheles stephensi larvae but was half the wild-type t
oxicity on Culex pipiens and Aedes aegypti larvae.
