Outline of Final Research Achievements |
Since symbiosis requires a balance of growth with each other, it is considered that plants have a molecular mechanism that transmits to symbiotic fungi whether they need symbiotic fungi or not. Here, we found a peptide that artificially constructs a peptide secreted extracellularly and changes the morphology of symbiotic filamentous fungi. In order to clarify whether this indicates symbiotic induction of symbiotic fungus, we constructed a transformant that overexpresses the gene encoding the candidate peptide and a transformant that suppresses the gene expression, and infects Ct bacteria. The growth rates of wild-type and transformants were compared. As a result, it was found that the transformants overexpressing the peptide tended to promote the growth more than the wild type.

Academic Significance and Societal Importance of the Research Achievements |
植物自身が、共生菌を増加してほしい状況か、細胞を抑制してほしい状況か、を伝達する分子メカニズムが存在するはずである。分子メカニズムを明らかにできた際には、植物共生菌を人為的にコントロールした農法に繋がる可能性がある。
