由英国和秘鲁两国联合组成的一个研究小组正在利用遗传工程技术改良甘薯的性状。他们将豇豆细胞中的某种特定的基因取出转移到甘薯细胞中,使甘薯获得抵抗害虫的性状,培育出抗虫甘薯新品种。甘薯是许多发展中国家的重要粮食作物。人们认为这项创造甘薯新品种的研究项目可给穷国带来
A team of researchers from the United Kingdom and Peru are using genetic engineering techniques to improve sweet potato traits. They will be a cowpea cells in a particular gene removed and transferred to sweet potato cells, so that sweet pests get resistance to traits, breed new varieties of insect-resistant sweet potato. Sweet potatoes are important food crops in many developing countries. It is thought that this research project to create a new sweet potato variety can be brought to poor countries
