摘要:
?豆科作物因其丰富的蛋白质含量而成为人类食品和动物饲料的重要原料。豆科作物具有与根瘤菌形成根瘤固定空气中氮素的能力，这不仅减少了化学肥料的使用，同时还起到培肥地力、改善农田土壤质量、促进农业可持续发展的作用。然而，豆科作物的共生固氮过程极易受环境胁迫、尤其是干旱胁迫的影响。本文简要探讨了根瘤菌在共生固氮应对干旱胁迫过程中所起的作用，着重论述了寄主植物碳代谢、氮代谢及氧气平衡三方面的调节机制，并探讨了氧化胁迫、碳氮互作及硫代谢在调控机制研究中的重要意义。
Abstract:
?Legume crops are the important resource of human food and animal feed with their high protein content.Many legume crops have the ability to form root nodules with rhizobia to fix nitrogen from air,which not only reduce the use of chemical fertilizers,but also enhance the soil fertility,improve soil quality and promote the sustainable development of agriculture.However,the process of symbiotic nitrogen fixation of legumes is vulnerable to environmental stress,especially to drought stress.This paper discussed the role of rhizobia in the process of symbiotic nitrogen fixation response to drought stress,especially the regulation mechanism of carbon metabolism,nitrogen metabolism,and the oxygen balance in the host plant,as well as the significance of oxidative stress,carbon and nitrogen interaction,sulfur metabolism in the regulation mechanism.
