متن کاملReview Protease Interactions With Bacillus thuringiensis Insecticidal Toxins
The microbe Bacillus thuringiensis (Bt) produces crystals that contain insecticidal crystal proteins (ICPs) used to control many major pests. ICPs are degraded by proteases from a variety of sources, including those endogenous to the bacterium, those purified from animals and plants, or those found in insects. Proteases in the bacterium function in protein metabolism during sporulation; in some...
متن کاملInteractions of transgenic Bacillus thuringiensis insecticidal crops with spiders (Araneae)
Genetically modified crops expressing insecticidal proteins from Bacillus thuringiensis (Bt) have dramatically increased in acreage since their introduction in the mid-1990’s. Although the insecticidal mechanisms of Bt target specific pests, concerns persist regarding direct and indirect effects on non-target organisms. In the field, spiders may be exposed to Bt toxins via multiple routes, incl...
متن کاملThe plcR regulon is involved in the opportunistic properties of Bacillus thuringiensis and Bacillus cereus in mice and insects.
Bacillus thuringiensis has been widely used for 40 years as a safe biopesticide for controlling agricultural pests and mosquitoes because it produces insecticidal crystal proteins. However, spores have also been shown to contribute to overall entomopathogenicity. Here, the opportunistic properties of acrystalliferous B. thuringiensis Cry(-) and Bacillus cereus strains were investigated in an in...
متن کاملBiochemical homology between crystal and spore protein of Bacillus thuringiensis.
The crystalline inclusion of Bacillus thuringiensis, dissolved in 8 m urea containing 10% 2-mercaptoethanol and dialyzed to pH 8.3 to 8.5, was compared with a fraction obtained by the same extraction procedure from spores broken by dry rupture. The two fractions behaved similarly on chromatography with Sephadex G-100 and diethylaminoethyl cellulose. The preparations behaved identically on acryl...
