Transgenic crops expressing Bacillus thuringiensis toxins and biological control

open access: yesNature Biotechnology, 2006
The area devoted to growing transgenic plants expressing insecticidal Cry proteins derived from Bacillus thuringiensis (Bt) is increasing worldwide. A major concern with the adoption of Bt crops is their potential impact on nontarget organisms including biological control organisms. Regulatory frameworks should advocate a step-wise (tiered) approach to

In Search of Proximate Triggers of Anthrax Outbreaks in Wildlife: A Hypothetical Individual-Based Model of Plasmid Transfer within Bacillus Communities

open access: yesDiversity, 2023
Bacillus anthracis, the causative agent of anthrax in humans, livestock, and wildlife, exists in a community with hundreds of other species of bacteria in the environment. Work on the genetics of these communities has shown that B.

Expression of the Bacillus thuringiensis vip3A Insecticidal Toxin Gene Is Activated at the Onset of Stationary Phase by VipR, an Autoregulated Transcription Factor

open access: yesMicrobiology Spectrum, 2022
The Vegetative insecticidal protein Vip3A is produced by some Bacillus thuringiensis strains from the mid-log growth phase to sporulation. Although Vip3A is important for the entomopathogenicity of B.

Aedes cadherin receptor that mediates Bacillus thuringiensis Cry11A toxicity is essential for mosquito development. [PDF]

open access: yes, 2020
Aedes cadherin (AaeCad, AAEL024535) has been characterized as a receptor for Bacillus thuringiensis subsp. israelensis (Bti) Cry11A toxins. However, its role in development is still unknown.

Redesigning Bacillus thuringiensis Cry1Aa toxin into a mosquito toxin [PDF]

open access: yesProtein Engineering, Design and Selection, 2006
The Bacillus thuringiensis crystal protein Cry1Aa is normally selectively active to caterpillar larvae. Through rational design, toxicity (microg/ml) to the mosquito Culex pipiens was introduced by selected deletions and substitutions of the loop residues of domain II. Toxicity to its natural target Manduca sexta was concomitantly abolished.
