Abstract: Nod factors (lipo-chito-oligosaccharides,LCOs) are signal molecules produced by rhizobium in effects of flavonoids secreted by plant roots, play an important role in the process of symbiosis. Nod factors recognize signals by using a certain mechanism, binding to a putative receptor (Nod factor binding protein), via the signaling ways activated by Nod factors such as calcium mediated signal transduction and phospholipid signaling way, induce a series of plant response, such as depolarization of root hair membrane, dividation of cotex and expression of nodulin genes. Moreover, Nod factor perception and signaling is regulated by some gene and feedback mechanism. A review will be established in this paper to introduce the perception mechanism, signal transduction ways and feedback regulation of rhizobium Nod factor in leguminous plants.
