Bt toxin proteins

Advances in safety studies of soil Bt toxin proteins released from transgenic Bt crops

转Bt基因作物Bt毒蛋白在土壤中的安全性研究

The application of Coleoptera - specific Bt toxin proteins by means of the technique of genetic engineering in transgenic plants provides a new way of controlling this pests .

利用基因工程技术把具有杀鞘翅目活性的Bt杀虫晶体蛋白基因转入植物，培育抗鞘翅目新品种是控制其危害的一条新途径。

So this situation needs to undertake an immediate study in a systemic way to assess the ecological risks caused by Bt toxin proteins released by transgenic crops .

因此深入、系统地研究和评价转Bt作物释放的Bt毒素对土壤生态系统的风险迫在眉睫。

The spatial dynamics of Bt toxin proteins in the same period were consistent . The Bt toxin protein content of functional leaves was highest , and it was more than flowers , buds and other reproductive organs .

Bt毒蛋白在各时期的含量均表现为功能叶中最高，大于花、蕾等繁殖器官。
