Abstract:
Legumes and several plant species in the monophyletic nitrogen-fixing clade produce root nodules that function as symbiotic organs and establish mutualistic relationships with nitrogen-fixing bacteria. The modes of nodule organogenesis are distinct from those of lateral root development and also differ among different types of nodules formed in legumes and actinorhizal plants. It is considered that the evolution of new organs occurs through rearrangement of molecular networks interposed by certain neo-functionalized factors. Accumulating evidence has suggested that root nodule organogenesis involves root or lateral root developmental pathways. This review describes the current knowledge about the factors/pathways acquired by the common ancestor of the nitrogen-fixing clade in order to control nodule organogenesis.
