| Outline of Final Research Achievements |
In this research project, we aimed to elucidate the mechanism of activation of cell functions and plant growth promoting functions by REE of phytosymbiotic bacteria, such as methylotrophic bacteria and rhizobia. First, regarding the control mechanism of REE-dependent methanol metabolism of methylotrophic bacteria and rhizobia, the structural characteristics of methanol dehydrogenase (MDH) was shown, and regulation mechanism of its expression and activation mechanism of cell proliferation are mainly demonstrated. In addition, it could be to show the details of the structure of MDH from rhizobia and the uptake mechanism of REE into the cell.
In addition, we found the growth-promoting function of Arabidopsis thaliana by REE-dependent methylotrophic bacteria, and were able to show that it has the ability to promote root growth in particular.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、私たちが見出したREEを生命活動に利用する最初の事例であるREE依存型メタノール代謝系の生態系における機能と役割を解明するのみならず、その細胞機能を作物生育促進に活用するものである。REE依存型メタノール生育をする微生物は自然界に広く分布することが推測されており、その生態系での役割を知る以上にその細胞機能の新たな活用は大きな学術的・社会的意義を持つものと考えられる。
