Flavonoids have many diff erent roles. They are responsible for fl ower colors, are protectants against ultraviolet light, and act as phytoalexins against pathogens (Harborne and Williams, 2000). Extensive studies exist about their potential to serve as scavengers of reactive oxygen species and as phytoestrogens (Harborne and Williams, 2000; Nij veldt et al., 2001). One of the best-understood and most specifi c functions, however, is their role in the establishment of the rhizobia–legume… CONTINUE READING
