摘      要：Legumes,unlike most land plants,can form symbiotic root nodules with nitrogen-fixing bacteria to secure nitrogen for *** formation of nitrogen-fixing nodules on legume roots requires the coordination of rhizobial infection at the root epidermis with cell division in the *** nodules house the nitrogen-fixing rhizobia in organelle-like structures known as symbiosomes,which enable nitrogen fixation and facilitate the exchange of metabolites between the host and *** addition to this beneficial interaction,legumes are continuously exposed to would-be pathogenic microbes;therefore the ability to discriminate pathogens from symbionts is a major determinant of plant survival under natural ***,we summarize recent advances in the understanding of root nodule symbiosis signaling,transcriptional regulation,and regulation of plant immunity during legume-rhizobium *** addition,we propose several important questions to be addressed and provide insights into the potential for engineering the capacity to fix nitrogen in legume and nonlegume plants.
