Bacillus thuringiensis and Its Pesticidal Crystal Proteins
E. Schnepf,Neil Crickmore,J. Van Rie,Didier Lereclus,J. Baum,Jerald S. Feitelson,Daniel R. Zeigler,Donald H. Dean +7 more
TL;DR: Researchers are reporting promising results in engineering more-useful toxins and formulations, in creating transgenic plants that express pesticidal activity, and in constructing integrated management strategies to insure that these products are utilized with maximum efficiency and benefit.

Biology, Ecology, and Management of the Diamondback Moth
N. S. Talekar,Anthony M. Shelton +1 more
TL;DR: Lack of parasitoids in a particular area may have occurred because the diamondback moth is better able than its natural-enemy complex to become established in newly planted cmcifers.

Revision of the Nomenclature for the Bacillus thuringiensis Pesticidal Crystal Proteins
Neil Crickmore,Daniel R. Zeigler,Jerald S. Feitelson,E. Schnepf,J. Van Rie,Didier Lereclus,J. Baum,Donald H. Dean +7 more
TL;DR: A new nomenclature, based on hierarchical clustering using amino acid sequence identity, is proposed, consisting of 133 crystal proteins comprising 24 primary ranks are systematically arranged.

TL;DR: In this article, a synthetic gene encoding a truncated version of the CryIA(b) protein derived from Bacillus thuringiensis was introduced into immature embryos of an elite line of maize using microprojectile bombardment.
Journal ArticleDOI
The mode of action of Bacillus thuringiensis endotoxins.
TL;DR: The use of synthetic organic insecticides developed during the last half of this century may pose risks to human health and can cause environmental damage, Consequently, interest has developed in using alternative strategies for insect pest management, including Bacillus thuringiensis toxins as insecticides.

Comparative toxicity of Bacillus thuringiensis var. israelensis crystal proteins in vivo and in vitro.
Chris N. Chilcott,David J. Ellar +1 more
TL;DR: In assays against a range of insect cell lines, the activated form (25 kDa) of the 27 kDa protein was generally cytotoxic with the lowest LC50 values in vitro, and each showed a unique toxicity profile which, in the case of the 130 kDa preparation, was restricted to Anopheles and Culex cell lines.

Molecular cloning and characterization of the insecticidal crystal protein gene of Bacillus thuringiensis var. tenebrionis
TL;DR: The insecticidal crystal protein gene of the coleopteran-toxic Bacillus thuringiensis var.

Isolation and characterization of EG2158, a new strain of Bacillus thuringiensis toxic to coleopteran larvae, and nucleotide sequence of the toxin gene
TL;DR: A novel strain of Bacillus thuringiensis was isolated from soybean grain dust from Kansas and found to be toxic to larvae of Leptinotarsa decemlineata (Colorado potato bectle), and the sequence of the 73 kDa protein was found to have regions of similarity with several B. israelensis crystal proteins.

Bacillus thuringiensis toxin inhibits K+-gradient-dependent amino acid transport across the brush border membrane of Pieris brassicae midgut cells
V. Franca Sacchi,Paolo Parenti,Giorgio M. Hanozet,Barbara Giordana,Peter Lüthy,Michael G. Wolfersberger +5 more
TL;DR: The luminal membrane of larval midgut cells is the site of action of insecticidal delta‐endotoxin from Bacillus thuringiensis and the toxin increases the K+ permeability of the membrane.

Molecular cloning and the nucleotide sequence of the Mr 28 000 crystal protein gene of Bacillus thuringiensis subsp. israelensis.
TL;DR: It was concluded that transcription of the Bacillus thuringiensis subspecies israelensis gene is restricted to early sporulation stages and regulation signals are poorly recognized by E. coli RNA polymerase.
