| 摘要 |
Chimeric insecticidal proteins comprise at least part of a <u>Bacillus thuringiensis</u> delta -endotoxin fused to a venom-derived insecticidal protein, such as the AaHIT peptide obtainable from <u>Androctonus australis</u> Hector. The delta -endotoxin portion protects the venom-derived protein and delivers it to the insect gut. DNA constructs encoding such chimeric proteins may be used to express said proteins in biological organisms. Exposure of insects to the chimeric insecticidal proteins is achieved through application to plants of an insecticidal composition containing said proteins or through expression of said proteins within transgenic plants. |
