中国是世界产棉大国，由于虫害的连年发生，给棉花生产造成了巨大的经济损失。为解决制约棉花生产发展的这一重大难题，笔者承担了国家“８６３”棉花抗虫基因工程研究课题。目前取得的新进展如下。１．转Ｂｔ杀虫基因抗虫棉研究根据Ｂｔ杀虫蛋白质的氨基酸序列，按照植物...
China is a big cotton-producing country in the world. As a result of successive pests, it has caused huge economic losses to cotton production. In order to solve this major problem restricting the development of cotton production, the author undertook the research topic of “863” cotton insect-resistant genetic engineering. The new progress made so far is as follows. 1. Bt insecticidal insect-resistant genetically modified cotton Bt insecticidal protein based on the amino acid sequence, according to plant ...
