日本三菱化成工业公司和三菱商事公司共同设立的植物工学研究所，首次用插入外来基因的水稻细胞成功获得稻亩再生植株，这一成就使应用基因工程方法培育耐病虫害水稻新品种的技术又前进了一步。这次插入水稻细胞的基因共两种，一是对潮霉素（一种抗生素）具有抵抗力的基因；一 Japan’s Mitsubishi Chemical Industry Corporation and Mitsubishi Corporation co-founded the Institute of Plant Engineering, the first use of foreign genes inserted into rice cells succeeded in obtaining acres of regenerated plants, the success of genetic engineering methods to cultivate new pest-resistant varieties of rice technology and advance One step. There are two genes that are inserted into rice cells this time. One is a gene that is resistant to hygromycin (an antibiotic); one
