目前,因与病虫害防治有关的各类基因的发现,以及植物转基因和微生物重组技术的一系列突破,用于农业植物保护的基因工程产品,已得到大力开发并在农业生产上实现了商业化的应用。换言之,转基因工程这一新技术,已在农业生产中大显身手,展示了广阔的前景。首先,是培育抗病虫害的新品种。病虫害是农作物的大敌,全世界每年有1/3的粮食遭其吞噬,经济损失是惊人的。因此,世界各国科学家如美国、比利时等国家的遗传学家利用基因工程把昆虫的毒素基因转移到棉花、玉米、烟草、番茄等作
At present, due to the discovery of various genes related to pest and disease control as well as a series of breakthroughs in plant genetically modified and microbial recombinant technologies, genetically engineered products for plant protection of agriculture have been vigorously developed and commercialized in agricultural production application. In other words, the new technology of transgenic engineering has shown its full promise in agricultural production and has shown a bright future. First of all, it is to cultivate new varieties of pests and diseases. Pests and diseases are the enemy of crops. One-third of the world’s grain is swallowed by them every year, and the economic loss is staggering. Therefore, geneticists in countries all over the world, such as the United States and Belgium, use genetic engineering to transfer the insect toxin genes to cotton, corn, tobacco and tomato
