Outline of Final Research Achievements |
In this project, we constructed a highly efficient inoculum system of phytoplasma, a non-cultivating phytopathogenic bacteria. Using this inoculation system, phytoplasma was inoculated into Arabidopsis plants with various genetic background. As a result, it was suggested that plant hormone contributes to the symptom development by phytoplasma. In addition, we constructed a drug screening system for phytoplasma, and identified several novel antimicrobials effective for phytoplasma.

Academic Significance and Societal Importance of the Research Achievements |
本研究では、ファイトプラズマの病徴の進展と植物ホルモンとの間の関連性が示唆されたが、これはファイトプラズマという特異な細菌がどのように宿主と関わり感染を成立させるかを明らかにする上で重要な知見である。加えて、本研究で確立した接種系により、これまで研究手法が限られていたファイトプラズマの研究が容易になることが見込まれる。したがって、本研究を基盤として、ファイトプラズマの感染機構や防除法に関する研究が一層進展することが期待される。
