抗虫棉花在我国大面积的推广,使越来越多的人们了解到这种不用农药的作物的优越性,并展示出生物技术在农业中运用的美好前景。其实,1987年美国就成功地将B.t.(苏云金芽孢杆菌)毒蛋白基因转入棉花,培育出抗虫棉花植株,并于1993年提出抗虫植物专利。 早在1983年,比利时Gent大学Maro Van Montagu和Jeff Schell为首的研究小组和美国孟山都公司Rob Frally为首的研究小组等把根癌农杆菌(一
The popularization of insect-resistant cotton in our country has led more and more people to understand the advantage of this non-pesticide crop and shows the bright prospect of using biotechnology in agriculture. In fact, in 1987 the United States successfully transferred the B.t. (B. thuringiensis) toxic protein gene into cotton and developed insect-resistant cotton plants. In 1993, it proposed the patent on insect-resistant plants. As early as 1983, a research team headed by Maro Van Montagu and Jeff Schell of the University of Gent in Belgium and Rob Frally, a research group led by the U.S. Monsanto Company, put Agrobacterium tumefaciens
