Construction of a Bacillus thuringiensis genetically-engineered strain harbouring the secreted Cry1Ia delta-endotoxin in its crystal
( Springer Netherlands , 2011 , Article)
Unlike other Bacillus thuringiensis Cry proteins, Cry1 Ia does not form a crystal since it is a secreted delta-endotoxin. We have engineered a Cry1 Iac chimeric protein by substituting the C-terminal part of Cry1 Ia by the ...
Agrotis segetum midgut putative receptor of Bacillus thuringiensis vegetative insecticidal protein Vip3Aa16 differs from that of Cry1Ac toxin
( Elsevier Inc. , 2013 , Article)
Considering the fact that Agrotis segetum is one of the most pathogenic insects to vegetables and cereals in the world, particularly in Africa, the mode of action of Vip3Aa16 of Bacillus thuringiensis BUPM95 and Cry1Ac of ...
Comparative study of Bacillus thuringiensis Cry1Ia and Cry1Aa delta-endotoxins : activation process and toxicity against Prays oleae
( Elsevier Inc. , 2010 , Article)
Cry1Ia and Cry1Aa proteins exhibited toxicities against Prays oleae with LC(50) of 189 and 116 ng/cm(2), respectively. The ability to process Cry1Ia11 protoxin by trypsin, chymotrypsin and P. oleae larvae proteases was ...
Vegetative insecticidal protein of Bacillus thuringiensis BLB459 and its efficiency against Lepidoptera
( Elsevier Ltd , 2017 , Article)
Bacillus thuringiensis strain BLB459 supernatant showed a promising activity against Lepidopteran pests with extremely damages in the larvae midgut. Investigations of the genes that encode secreted toxin demonstrated that ...
