农作物自主灭虫法:科学家为植物“打疫苗”取之于害虫基因,转入于植物体内,助其发挥天然毒素作用,从而抑制害虫危害,却对人体和环境无毒。中科院上海生科院植物生理生态研究所11月5日宣布:科学家的这项发明有可能发展成为不使用杀虫剂而使转基因农作物自主灭虫的新方法,相关成果作为“亮点论文”发表于国际著名杂志《自然·生物技术》上。该所研究员陈晓亚院士及其博士生毛颖波,选择棉花和棉铃虫作为项目研究对象。我国棉花种由棉铃虫危害,每年造成的经济损失就达数十亿元,严重年份甚至超过100亿元。于是,科研人员致力于分离出棉铃虫的这种“解毒基因”P450,并针对P450基因“装配”出双链RNA分子,从
Autonomous control of crop insects: scientists for the plant “vaccine ” taken from the pest genes, transferred to plants, to help play its role in natural toxins, thereby inhibiting pests, but non-toxic to humans and the environment. Institute of Plant Physiology and Ecology, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences announced on November 5: This invention of the scientists is likely to develop into a new method for controlling pests of genetically modified crops without using insecticides. Relevant achievements have been published as “Highlights Paper” Posted in the internationally renowned magazine “Nature · Biotechnology”. The researcher Chen Xiaoya academician and his doctoral student Mao Yingbo, cotton and cotton bollworm as the project object of study. Cotton bollworms in our country are endangering the economic losses caused by the bollworms every year, reaching billions of dollars, even exceeding 10 billion yuan in severe years. As a result, researchers are dedicated to isolating this “detoxification gene” P450 from Helicoverpa armigera and “double-stranded” RNA molecules against the P450 gene from
