Synergism of Bacillus thuringiensis toxins by a fragment of a toxin-binding cadherin.
The insecticidal crystal proteins produced by Bacillus thuringiensis (Bt) are broadly used to control insect pests with agricultural importance. The cadherin Bt-R(1) is a binding protein for Bt Cry1A toxins in midgut epithelia of tobacco hornworm (Manduca sexta). We previously identified the Bt-R(1) region most proximal to the cell membrane (CR12-MPED) as the essential binding region required f...
متن کاملRole of GPI-Anchored Membrane Receptors in the Mode of Action of Bacillus thuringiensis Cry Toxins
Insect pests are the major cause of damage to commercially important agricultural crops. Chemical pesticides have long-term detrimental effects, leading to irreversible damage to the environment and elimination of natural predators. Also, several hundred insect species have developed resistance to one or more chemical insecticides. There is, therefore, a need for environmentally safe pest contr...
متن کاملThe First Cry2Ac-Type Protein Toxic to Helicoverpa armigera: Cloning and Overexpression of Cry2ac7 Gene from SBS-BT1 Strain of Bacillus thuringiensis
The Cry (crystal) proteins from Bacillus thuringiensis are known to have toxicity against a variety of insects and have been exploited to control insect pests through transgenic plants and biopesticides. B. thuringiensis SBS BT-1 carrying the cry2 genes was isolated from soil samples in Pakistan. The 2-kb full length cry2Ac gene was cloned, sequenced, and submitted to the EMBL DNA database (Acc...
متن کاملSAFETY OF Bacillus thuringiensis Proteins Used to
This document reviews the safety assessment for Bacillus thuringiensis (Bt) delta-endotoxin proteins that have been introduced into agricultural crops to provide protection against insect pests. Information is provided on the scientific basis for U.S. EPA approvals for the introduction of Bt proteins into agricultural crops. Relevant to these approvals is the extensive data base on Bt protein s...
متن کاملApplication of Membrane Separation Technology in Downstream Processing of Bacillus thuringiensis Biopesticide: A Review
Bacillus thuringiensis (Bt) has been extensively used in biopesticidal formulations due to its safe environmental and human health records. The widespread use of Bt is often challenged by production as well as formulation costs which are in direct contact with downstream processing, i.e. the separation/purification step. Downstream separation/purification efficacy governs the marketabi...
