Rhizobia have the ability to infect and establish a N2-fixing symbiosis with many leguminous and a few nonleguminous plan. The result of this interaction is the formation of a novel plant organ, the nodule, where Nz fixation occurs. Research has shown that the establishment of this symbiosis requires coordinate bacterial and plant gene expression that is regulated through the mutual exchange of diffusible signal molecules. For example, each legume host exudes signals, mostly flavonoids, that induce the transcription of bacterial genes (i.e. nod, nol or nee genes), whose protein products are required for the infection proces
