Open AccessLarval midgut modifications associated with Bti resistance in the yellow fever mosquito using proteomic and transcriptomic approaches
Bacillus thuringiensis var. israelensis (Bti) is a natural larval mosquito pathogen producing pore-forming toxins targeting the midgut of Diptera larvae. It is used worldwide for mosquito control. Resistance mech...

Comparison of the localization of Bacillus thuringiensis Cry1A δ-endotoxins and their binding proteins in larval midgut of tobacco hornworm, Manduca sexta
Tobacco hornworm, Manduca sexta, is a model insect for studying the action of Bacillus thuringiensis (Bt) Cry toxins on lepidopterans. The proteins, which bind Bt toxins to midgut epithelial cells, are key factor...

Investigations of Bacillus thuringiensis Cry1 toxin receptor structure and function
Bacillus thuringiensis Cry1 proteins are highly toxic to some species of lepidopteran larvae. Cry proteins act on the brush border membrane through a multi-step process. The process includes Cry1 c...

Testing transgenes for insect resistance using Arabidopsis
One possible strategy to delay the selection of resistant insect populations is the pyramiding of multiple resistance genes into a single cultivar. However, the transformation of most major crops remains prohi...

Expression of a Bacillus thuringiensis cryIA(c) gene in transgenic peanut plants and its efficacy against lesser cornstalk borer
The invasion of peanut (Arachis hypogaea L.) pods and seeds by aflatoxin-forming species of Aspergillus is linked to injury by the lesser cornstalk borer and frequently causes a severe reduction in crop qualit...

The reconstruction and expression of a Bacillus thuringiensis cryIIIA gene in protoplasts and potato plants
A Bacillus thuringiensis (B.t.) cryIIIA δ-endotoxin gene was designed for optimal expression in plants. The modified cry gene has the codon usage pattern of an average dicot gene and does not contain AT-rich nucl...

Size and organization of a multigene family encoding phaseolin, the major seed storage protein of Phaseolus vulgaris L.
Solution hybridization kinetics and genomic nitrocellulose blot hybridization analyses show that the Phaseolus vulgaris L. (French bean) storage proteins (phaseolins) are encoded as a small, homologous, multigene...

An Insect Virus for Genetic Engineering: Develo** Baculovirus Polyhedrin Substitution Vectors
Baculoviruses are exceptionally attractive candidates as vectors for propagating and expressing exogenous DNAs in a eukaryotic (invertebrate) environment (Miller, 1981a). Among the features which make baculovi...
