Abstract
In recent years, a number of legume genes involved in the root nodule symbiosis has been identified in the model legumes, Lotus japonicus and Medicago truncatula. Among them, the distinct set of genes has been characterized as common sym, because they are also essential for another mutual interaction, the arbuscular mycorrhiza symbiosis.
Common sym are functionally conserved in non-nodulating plants, such as rice, and are essential for the arbuscular mycorrhiza symbiosis in rice. Furthermore, it has been revealed that common sym from rice could fully complement symbiosis defects in the corresponding Lotus japonicus mutants for both the root nodule symbiosis and the arbuscular mycorrhiza symbiosis.
In this presentation, we will report that the functional conservation analyses of legume-rhizobium symbiosis genes from rice in Lotus japonicus.
