 The continuous formation of new organs after the completion of embryogenesis allows plants to be flexible in a constantly changing environment. A unique example of adaptation to an environmental signal is the symbiosis of legumes with Rhizobium bacteria, which leads to the formation of a complete new organ, the root nodule. Inside these nodules, the hosted bacteria fix atmospheric nitrogen into ammonia that can be used by the plant. Homologues of nodulin genes (genes that are highly induced during nodule formation) can be found in non-legumes, suggesting that rhizobia have recruited genes involved in general plant development for nodule formation. The presence of nodulin homologues in non-legumes opens the possibility to compare the regulation and function of nodulins and nodulin homologues in legumes and non-legumes. We studied the regulation and function of the legume ENOD40 nodulin gene and its tomato homologue LeENOD40 in legumes and non-legumes.
