It produces a protein called Bt protoxin. 它会产生Bt原霉素的蛋白质。
Adsorption Characteristics of the Protoxin of Bacillus thuringiensis on Montmorillonite Particles 苏云金芽胞杆菌原毒素在蒙脱石上的吸附特性研究
The results were as follows: After the selections have been done for 16 generations, the cotton bollworm were more and more resistant to Bt pesticide, Bt protoxin and Bt transgenic cotton, and the resistance order was Bt pesticide> Bt protoxin> Bt transgenic cotton. 结果表明,经16代筛选,棉铃虫对3种Bt都可以产生抗性,抗性上升的快慢顺序是:Bt杀虫剂>Bt毒蛋白>转Bt基因棉。
The study provide a valuable option for resistance management, and on such a base, the role of disulphide in the protoxin stability and toxicity can be further achieved. 本研究提供了一种有潜在价值的抗性管理策略,对于阐明二硫键对原毒素分子的稳定性及毒性的影响具有重要意义。
