摘　　要：Nitrogen is an essential macroelement for plant growth and development.Although nitrogen makes up 78%of the air by volume,it cannot be directly used by plants.Most legumes can convert nitrogen in the air into ammonia that can be absorbed and utilized by plants through symbiosis with nitrogen-fixing microorganisms that occurs within rhizosphere called nodules.This symbiosis depends on signal recognition and communication between host(legume)and symbiont(rhizobial).The roots of legumes can release flavonoids into the rhizosphere,which induce rhizobia to synthesize and secrete Nod factors.Lysine-motif(LysM)-containing receptor-like kinases(LYKs)or LysM-containing proteins(LYPs)/LysM domain proteins(LYMs),which are located on the surface of roots cells,have been reported to play a key role in the recognition and establishment of symbiotic signals[1].However,how the receptor complexes are formed and functioning on the cell surface to coordinate bacterial infection and nodule organogenesis remained a challenging question to answer.
