Insecticidal and Potato Growth Stimulation Activity of Bacillus thuringiensis kurstaki HD-1

نویسندگان

چکیده

Bacillus thuringiensis (Bt) produces Cry toxins against pest insects. proteins are conformed by domains related to pore formation and recognition of protein receptors. Plant-induced systemic resistance (ISR) is triggered due attack, it could be activated sp. Tecia solanivora (Ts) a potato pest, susceptible Cry1Ac Cry1B proteins. This paper indicates the endorsement Bt kurstaki HD-1 (BtkHD1) in relation Ts control (Cry1Ac proteins), growth promotion, plant ISR pests BtkHD1-potato system. To ensure that ongoing quality BtkHD1 was maintained, crystal synthesis (microscopy), cry1 genes presence, production were checked. Bioassays larvae plantlets an silico analysis hybrid Cry1Ac-Cry1Ba infl uence performed. Bioassay on shows LC50 536 ng/cm2 diet. A promotion assay revealed effect length dry weight stems. The prospective took into account relevant factors affecting biological function focused domain II. In identification 15 68 completed. project serves validation toxicity based BtkHD1, including forward Cry1Ac1-Cry1Ba1, associated with this strain for eliciting pests.

Combining Hexanoic Acid Plant Priming with Bacillus thuringiensis Insecticidal Activity against Colorado Potato Beetle

Interaction between insect herbivores and host plants can be modulated by endogenous and exogenous compounds present in the source of food and might be successfully exploited in Colorado potato beetle (CPB) pest management. Feeding tests with CPB larvae reared on three solanaceous plants (potato, eggplant and tomato) resulted in variable larval growth rates and differential susceptibility to Ba...

Accumulation of the insecticidal crystal protein of Bacillus thuringiensis subsp. kurstaki in post-exponential-phase Bacillus subtilis.

A gene from Bacillus thuringiensis subsp. kurstaki that codes for a Lepidoptera-specific insecticidal toxin (delta-endotoxin) was engineered for expression in Bacillus subtilis. A low-copy-number plasmid vector that replicates in Escherichia coli and B. subtilis was constructed to transform B. subtilis with gene fusions first isolated and characterized in E. coli. Naturally occurring promoter s...
