Abstract

Over 4,000 different flavonoids are synthesized by plants (11), but their functions are poorly understood (10). One exception to that generalization is the role that flavonoids from legumes play in the induction of rhizobial nod genes (16). Although that phenomenon has been studied in diverse legumes and rhizobia, a wider role for exuded flavonoids in rhizosphere biology has not been established. One factor limiting a broader consideration of how flavonoids affect rhizosphere biology is the lack of detailed data on which compounds are actually released by a particular plant. The primary purpose of this discussion is to show how identifying the chemical structures of flavonoids released naturally from seeds (13) and roots (19) of alfalfa (Medicago sativa L.) has increased our understanding of rhizosphere biology. Initial data from an investigation designed to test if conclusions from alfalfa can be generalized to include common bean (Phaseolus vulgaris L.) will be mentioned.
