title: Plant isoflavonoids, pathogens and symbionts.
abstract: It has recently been discovered that when symbiotic Rhizobium and Bradyrhizobium cells are outside the plant they are also exposed to the isoflavonoid phytoalexins that are normally associated with pathogenic infections. How the symbionts elicit and respond to isoflavonoids may help to define the mechanisms that are used by other beneficial soil microorganisms to colonize plant roots.
