稻瘟病是水稻的主要病害,每年的发病面积占日本播种水稻总面积的40%多,仅农药费用每年就高达5亿美元以上。为预防此病,日本北陆稻作研究中心将卷心菜、白菜等蔬菜中制造有机抗菌作用蛋白体的基因移植入水稻细胞内,培育出来的蔬菜基因水稻能抵抗稻瘟病等

Rice blast is the main disease of rice. The annual incidence of disease is more than 40% of the total area planted with rice in Japan. The cost of pesticides alone is as high as 500 million U.S. dollars per year. In order to prevent this disease, Japan BeiLong Rice Research Center transplants genes of cabbage, Chinese cabbage and other vegetables that produce organic antimicrobial protein into rice cells. The genetically engineered rice that is cultivated can resist rice blast
