Wang G.L., and Li M.X., 2024, A comprehensive study on nitrogen fixation and growth and development regulation of leguminous plants, Legume Genomics and Genetics, 15(1): 1-12 (doi: 10.5376/lgg.2024.15.0001)

Legumes are important nitrogen fixers that play significant roles in agricultural sustainability and ecosystem functioning. This review studied the relationship between nitrogen fixation and growth & development regulation in legumes. Firstly, it introduced the mechanism of legume nitrogen fixation, including root nodule formation with rhizobia, the nitrogenase system and nitrogen fixation process, as well as the interaction between nodule formation and the nitrogenase system. Secondly, it discussed the impacts of nodule formation on plant growth and development, signaling communication between rhizobia and plants， and rhizobia-induced plant metabolic regulation. Further, it summarized the advances in molecular mechanism research, agricultural applications of legume nitrogen fixation and growth & development regulation, as well as its ecological impacts. Finally, it proposed future research directions and challenges, including unknown mechanisms of legume nitrogen fixation, interactions with other growth and development regulatory pathways, and application prospects in nitrogen management and agricultural sustainability. This review provides important references for further studies in the field of legume nitrogen fixation and growth & development regulation.
