日本农林省农业生物资源研究所日前发表的科研信息说,研究所应用转基因技术把功能增强了的壳质酶基因导入水稻,培育出了抗稻瘟病的水稻。壳质酶是一种分解酶,能够溶解病原菌的细胞壁,从而抑制病菌的生长。水稻中的这种酶能力微弱,不足以对病原菌产生抵抗力。这家研究所的西泽洋子等科研人员从水稻中把壳质酶的基因单独分离出来,运用基因技术使其经常地、强烈地发挥功能,然后使用土壤杆菌把这种基因导入水 Japan Agriculture, Forestry and Animal Husbandry Institute of Agricultural Biological Resources published a research report recently that the Institute of transgenic technology to enhance the function of the chitinase gene into rice, bred rice blast resistance. Chitinase is a degrading enzyme that dissolves the cell wall of pathogens and thus inhibits the growth of germs. This enzyme in rice is weak enough to be resistant to pathogens. Researchers such as Yonezawa Zeidai at the institute separately separate the genes for chitinase from rice and use gene technology to make it function frequently and strongly. Then Agrobacterium is used to introduce this gene into water
