"Salty" Rice Plant Boosts
Harvests{{/B}} British scientists are breeding a new generation of rice plants that will be able to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more. Tim Flowers and Tony Yeo, from’ Sussex University’s School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pair have recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council, to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice. It is e A. to find ways to prevent water pollution. B. to identify genes that promote growth in salty soil. C. to breed rice plants that taste salty. D. to find ways to remove excessive salt from soil. [多选题]用户产权设备检修工作完工后,必须由客户管理单位组织验收,并由客户管理单位向配网调控值班员汇报( )。
