英国威尔士作物育种站的科研工作者,正在开展利用分子生物工程改善作物抗寒性的研究。他们计划对某些作物的特殊性状加以利用。例如洋葱,当冬季绝大多数植物都停止生长时,它却具有持续生长的活力。该研究的第一步是找出某些 Researchers at the Welsh Crop Breeding Station in the UK are conducting research to improve the cold resistance of crops using molecular bioengineering. They plan to make use of the special traits of certain crops. For example, onions, which have a continuously growing vitality when most plants stop growing in winter. The first step in this research is to find out something
