美遗传工程学家把土壤寄生细菌苏芸金杆菌(Bacilllus tnuringinsis,简称Bt)的防蛀基因移植于核桃树体内,在该基因的生化作用下,使树体制造出一种高能量的Bt蛋白质,这种蛋白质可杀死咀嚼核桃叶子及果实的许多害虫,常见的有苹果蠹蛾、印度谷螟等鳞翅目幼虫.杀虫机理是:害虫食用含有该蛋白质的食物后,其消化系统遭到严重破坏而停食死亡。试验结果表明,该蛋白质对人、
The United States genetic engineering scientists to soil mulberry bacterium Bacillus thuringiensis Bacillus (Bacillus thuringiensis, Bt) moth gene transplanted in the walnut tree in the biochemical effect of the gene, make the tree to produce a high-energy Bt protein , A protein that kills many pests that chew on the leaves and fruits of walnuts, most commonly Lepidoptera larvae such as codling moth and Indian rice stem borer, etc. Insecticidal mechanisms are: Pests consume food containing the protein and their digestive system Serious damage and death die. The test results show that the protein on human,
