- 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.
