Rhizobium--plant signal exchange.
Nature. 1992; (6380): 655-60
Initial stages in the Rhizobium-legume symbiosis can be thought of as a reciprocal molecular conversation: transmission of a gene inducer from legume host to bacterium, with ensuing bacterial synthesis of a morphogen that is transmitted to the plant, switching the developmental fate of the legume root. These signal molecules have a key role in determining bacterium-host specificity and the purified Nod factor compounds provide useful new tools to probe plant cell function.
