Outline of Final Research Achievements |
A one of Lotus japonicus Fix- mutants, syp71 in which SYP71 gene coding for a SNARE protein is mutated, was analyzed to reveal a systemic signal compound transported from the shoot to the root via vascular bundles that controls nitrogen fixation activity of rhizobia in the nodules. Daidzein was appeared to be significantly effective for recovering weights of plants as well as nodules depressed in the syp71 mutant. In addition, analysis of a Lotus japonicus mutant uncovered that a nucleoporin GLE1 is involved in symbiotic association with rhizobia.
