Until recently it had been well established that the initial step in legume-rhizobia symbioses was flavonoid and Nod factor (NF) signaling. However, NF-independent symbiosis is now known to occur between Bradyrhizobium and some species of Aeschynomene. Since its discovery, this unusual symbiotic system has attracted attention, and efforts have been devoted to revealing the NF-independent symbiotic mechanism, although the molecular mechanisms of nodule initiation still remain to be elucidated… CONTINUE READING
