Structural Insights into Bacillus thuringiensis Cry, Cyt and Parasporin Toxins [PDF]
Toxins, 2014 Since the first X-ray structure of Cry3Aa was revealed in 1991, numerous structures of B. thuringiensis toxins have been determined and published. In recent years, functional studies on the mode of action and resistance mechanism have been proposed ...

Exploration of receptor binding of Bacillus thuringiensis toxins [PDF]
Memorias do Instituto Oswaldo Cruz, 1995 Wild type and mutant toxins of Bacillus thuringiensis delta-endotoxins were examined for their binding to midgut brush border membrane vesicles (BBMV). CryIAa, CryIAb, and CryIAc were examined for their binding to Gypsy moth (Lymantria dispar) BBMV.

Bacillus thuringiensis subsp. israelensis and Its Dipteran-Specific Toxins [PDF]
Toxins, 2014 Bacillus thuringiensis subsp. israelensis (Bti) is the first Bacillus thuringiensis to be found and used as an effective biological control agent against larvae of many mosquito and black fly species around the world.

Maintenance of Gut Microbial Balance via the Kynurenine Pathway Improves Larval Performance and Resistance to Bacillus thuringiensis in Spodoptera exigua. [PDF]
MicrobiologyopenCRISPR/Cas9‐mediated deletion of kmo in Spodoptera exigua abolished 8‐HQA production, disrupted gut microbial homeostasis, and promoted Enterococcus dominance in gut and oral secretion. Mutants exhibited impaired growth, delayed development, and increased susceptibility to Bacillus thuringiensis, highlighting a conserved role of the kynurenine pathway ...

Pollen Exposed to Aerial Pesticide Spray Is a Major Exposure Pathway for Stingless Bees [PDF]
Ecol EvolWe conducted a molecular ecology experiment to determine foraging of stingless bees and potential exposure routes for aerially applied pesticides. We found that 27% of forager bees brought back Bti to the hive, and that this is a major route for pesticide exposure.

Evaluation of synergism among Bacillus thuringiensis toxins [PDF]
Applied and Environmental Microbiology, 1992 A simple test for synergism among toxins is described and applied to previously reported data on independent and joint toxicities of insecticidal proteins from Bacillus thuringiensis. The analysis shows synergism between a 27-kDa (CytA) toxin and 130- or 65-kDa (CryIV) toxins from B. thuringiensis subsp. israelensis against Aedes aegypti larvae.
