| Outline of Final Research Achievements |
Root nodule symbiosis (RNS) and arbuscular mycorrhiza (AM) are mutualistic interaction with plants and rhizobia or arbuscular mycorrhizal fungi. It is known that RNS and AM supply nutrients each other and give a large growth promoting effect in both host plant and symbiotic microbes. In this study, we analyzed regulation mechanism of RNS and AM by plant hormone "gibberellin". We have discovered promoter regions that control expression of RNS and AM genes by gibberellin signaling, and have performed function analysis of these regions in symbiosis. From these analyses, we clarified the mechanism of interference to symbiotic signals and gene expression by gibberellin.
