ABSTRACT Legume plants commonly associate with both arbuscular mycorrhizal (AM) fungi and rhizobia thus enhance the acquisition of phosphorus (P) nitrogen (N) nutrition. Inoculation AM can promote nodulation N 2 fixation legume plants; however, underlying mechanisms remain poorly understood. Here, root exudates collected from AM‐colonised soybean showed greater accumulation specific flavonoids (daidzein genistein) phenolic acids (benzoic acid p ‐Hydroxybenzoic acid), significantly promoted nodulation. Furthermore, roots derived effectively increased rhizobial growth, chemotaxis, biofilm formation. Addition synthetic enhanced fixation, expression core genes in soybean. Overexpression a phenylalanine ammonia‐lyase gene, GmPAL2.4 markedly upregulated related to biosynthesis daidzein, genistein, benzoic acid, these transgenic plants, enhancing fixation. In summary, we demonstrated crucial role induced by symbiosis promoting rhizobium‐host symbiosis. This offers pathway for improving symbiotic efficiency through use compounds.
