Can Bacillus thuringiensis (Bt) corn residues and Bt-corn plants affect life-history traits in the earthworm Aporrectodea caliginosa?
TL;DR: Finely ground Bt-corn leaves added to soil had no deleterious effects on survival, growth, development or reproduction in A. caliginosa, even in high concentrations that could be considered as a worst-case scenario.

Intramolecular Proteolytic Cleavage ofBacillus thuringiensisCry3A δ-Endotoxin May Facilitate Its Coleopteran Toxicity
TL;DR: Interestingly a chymotrypsinized Cry3A product was soluble under neutral pH conditions, retained full activity against susceptible beetle larvae, and exhibited specific binding to Leptinotarsa decemlineatamidgut membranes.

TL;DR: In this article, a novel class of proteins and their receptors for controlling plant pests is described. But the present invention is drawn to a novel protein class and their receptor. And the present method is not suitable for the control of plant pests.

The chromosome map of Bacillus thuringiensis subsp. canadensis HD224 is highly similar to that of the Bacillus cereus type strain ATCC 14579
TL;DR: A physical map of the Bacillus thuringiensis subsp.
Journal ArticleDOI
Single-site mutations in the conserved alternating-arginine region affect ionic channels formed by CryIAa, a Bacillus thuringiensis toxin.
TL;DR: This study provides the first direct evidence of a functional role for domain III in membrane permeabilization and suggests that residues of the positive arginine face of block 4 interact with domain I, the putative pore-forming region of CryIAa.

Analysis of membrane and surface protein sequences with the hydrophobic moment plot.
TL;DR: An algorithm has been developed which identifies alpha-helices involved in the interactions of membrane proteins with lipid bilayers and which distinguishes them from helices in soluble proteins, and suggests four transmembrane helices and a surface-seeking helix in fragment B, the moiety known to have trans Membrane function.

TL;DR: The Gram-positive bacterium Bacillus thuringiensis produces proteins which are specifically toxic to a variety of insect species, and modified genes have been derived from bt2, a toxin gene cloned from one Bacillus strain.

Stable Transformation of Soybean (Glycine Max) by Particle Acceleration
TL;DR: Experiments using this protocol have resulted in mature RO and R1 plants expressing the introduced gene(s), regarded as a major step in the practical application of genetic engineering to the useful modification of food-crop species.

TL;DR: With the exception of the Lepidopteran cell line, Choristoneura fumiferana 63 CF1, this soluble crystal delta-endotoxin protein showed no in vitro or in vivo toxicity, and no haemolytic activity.
