马铃薯晚疫病是对土豆威胁最大的真菌性病害。英国研究人员最新研发出1种转基因土豆,不仅可以抵御这种病害,而且产量高。马铃薯晚疫病由1种喜爱潮湿环境的致病真菌引起,患病作物的叶子和根茎均会腐烂。欧洲农民为预防这种病害,在土豆生长季中喷洒10余次农药。据估算,这一病害目前仍给全球农业造成不小的损失。英国塞恩斯伯里实验室等机构的研究人员从南美洲1种野生土豆中获取1种基因,将其
Late blight of potato is a fungal disease that is the most threatening to potatoes. British researchers recently developed a genetically modified potato, not only to resist this disease, but also high yield. Phytophthora infestans is caused by a pathogenic fungus that loves dampness and the leaves and rhizomes of diseased crops will decay. To prevent this disease, European farmers spray more than 10 pesticides during the growing season of potatoes. It is estimated that this disease still causes a considerable loss to global agriculture. Researchers at Sainsbury’s Laboratory in the United Kingdom and other institutes obtained 1 gene from 1 wild potato in South America,
