中科院微生物研究所与兄弟所合作。率先成功地克隆了对鳞翅目害虫有高效杀灭作用的毒蛋白基因,经改造后装入了自己构建的真核生物高效表达载体,并通过农杆菌转入烟草生产品种,从中选出了对烟青虫有90—100％毒杀作用的转基因工程植株。这一成果为进一步提高转基因植物的杀虫效果展示了广阔的前景。苏云金杆菌在芽孢形成期能产生一种可特异地毒杀棉铃虫、红铃虫、五毒蛾、松毛虫等主要农林业害虫,
Chinese Academy of Sciences Institute of Microbiology and brothers by the cooperation. The first successful cloning of Leptospira pests efficient killing effect of toxic protein gene, after transformation into its own eukaryotic efficient expression vector, and transferred into the tobacco production by Agrobacterium species, from which 90-100% of tobacco budworm toxic effects of genetically engineered plants. This achievement has shown broad prospects for further improvement of the insecticidal effect of transgenic plants. Bacillus thuringiensis in the sporulation period can produce a can specifically kill the cotton bollworm, pink bollworm, five poison moths, pine caterpillars and other major agricultural and forestry pests,
