让小麦、水稻等农作物自行固氮是科学家多年来不懈追求的目标,这样不仅可以少施氮肥,使粮食大幅度增产,而且还能保护环境。然而,固氮基因的转移并实现固氮,仅在大肠杆菌和酵母菌这类原核生物中获得了成功,在真核生物如小麦、水稻中,固氮基因却未能表达。我想,科学家们应该是希? The nitrogen fixation of crops such as wheat and rice is a goal that scientists have been relentlessly pursuing over the years. This will not only reduce the use of nitrogenous fertilizers, increase grain production, but also protect the environment. However, the transfer of nitrogen-fixing genes and the achievement of nitrogen fixation have only been successful in prokaryotes such as E. coli and yeast. In eukaryotes such as wheat and rice, nitrogen fixation genes have not been expressed. I think scientists should be Greek?
