Outline of Final Research Achievements

In Lotus japonicus-Rhizobium root nodule symbiosis, rhizobia enter host cells through an intracellular invasion system that depends on the formation of a root-hair infection thread (IT). While IT-mediated intracellular rhizobia invasion is thought to be the most advanced and dominant invasion system, our understanding of the underlying genetic mechanisms relevant to IT formation is incomplete. In this study, we identify a L. japonicus nodulation-deficient mutant, with a mutation in a novel locus designated as LATE NODULATION (LAN), in which nodulation is significantly delayed. LAN encodes a putative component involved in transcriptional regulation. These results suggest that the predominant role of LAN-mediated gene transcription is to establish swift and efficient production of functional nodules by promoting intracellular rhizobial accommodation.
