由石家庄市农科院召开的新闻发布会上获悉:列入国家 “863”重大关键项目的“抗虫棉研制”项目喜结硕果,SGK321双价转基因抗虫棉通过河北省品种审定。据介绍,SGK321双价转基因抗虫棉同现有的单价抗虫棉相比,最大的优点对于其具有更稳定持久的抗虫性。双价抗虫棉中的BT基因产生杀虫蛋白,破坏棉铃虫的消化系统导致其死亡,CPTI基因产生胰蛋白酶抑制剂,使棉铃虫的蛋白酶失去活力,不能消化食物中的蛋白质,其得不到充足的
From Shijiazhuang Academy of Agricultural Sciences held a press conference was informed that: included in the national “863 ” major key projects “insect resistant cotton research ” project hi results, SGK321 bivalent transgenic insect-resistant cotton through Hebei varieties Validation. According to reports, SGK321 bivalent transgenic cotton with the existing unit price of cotton, the biggest advantage for its more stable and lasting insect resistance. The BT gene in the bivalent insect-resistant cotton produces insecticidal protein and damages the digestive system of the cotton bollworm. The CPTI gene produces trypsin inhibitor, which inactivates the proteinase of the cotton bollworm and can not digest the protein in the food. To adequate
