科学家发现了一种遗传机制可以终止正在威胁小麦作物的“破坏性”病害,一种由真菌引起的壳针孢叶斑病的蔓延,这种病害被视为是对欧洲小麦和其它小麦产区的产量具有最大威胁的病害,这是因为当前所使用的杀真菌剂对该病的抗性株系的效果越来越小。研究人员发现了一个小麦蛋白Ta R1,它是使Zymoseptoriatritici无症兆生长的关键。通过操控种植在实验室控制环境下的小麦叶片中的Ta R1蛋白,即通 Scientists have discovered a genetic mechanism that can stop the “destructive” disease that is threatening the wheat crop, a fungus-caused spread of the needle-leaf disease that is believed to be responsible for the breakdown of European wheat and other wheat Yields in the producing areas have the greatest threat to the disease, as the currently used fungicides have less and less effect on the resistant lines of the disease. The researchers discovered a wheat protein called Ta R1, which is the key to the silent growth of Zymoseptoriatritici. By manipulating the Ta R1 protein in wheat leaves planted under laboratory control, the pass
