Spaink HP: Flavonoids as regulators of plant development: new insights from studies of plant-rhizobia interactions. In Recent Advances in Phytochemistry, vol 32. Edited by Verpoorte R, Downum K, Romeo J. New York; Plenum Publishing Company: 1998, in press. In the rhizobia-plant interaction flavonoids produced by the plant are the inducers of LCO synthesis by the bacteria. This is not the only function of flavonoids in this symbiosis. The author discusses functions of flavonoids in relation to nodulation and presents the hypothesis that flavonoids have been chosen in evolution as inducers of nod-genes, because they are unique secreted markers for the hormonal balance of the root which, therefore, indicates the position of the root which is susceptible for the induction of cell division leading to root nodules.
