Outline of Final Research Achievements

In this study, we search for varieties that are resistant to Fusarium, and search for peptide candidates that are thought to be involved in resistance in the transcriptome of those varieties. A group of Malaysian collaborators selected varieties with high and low antibacterial properties against Fusarium. After infecting the selected varieties with Fusarium, total RNA was extracted as a sample for transcriptome analysis, and transcriptome analysis was performed in Japan. In particular, we focused on the genes encoding 26 secretory peptides that are highly induced in varieties with low antibacterial properties, and investigated the antibacterial activity by adding the peptides to Fusarium. As a result, it was clarified that the two peptides show antibacterial activity.

Academic Significance and Societal Importance of the Research Achievements

バナナは世界中の熱帯地方で栽培されているにも関わらず、バナナの栽培品種は種子ができず、クローンを上次ぐことで栽培面積を増やしている。そのため、栽培品種は均一化しており、特有の病害や環境ストレスに非常に弱いストレスを持つことが近年大きな問題になっている。特に、バナナの出荷を不可能にさせるパナマ病あるいは新パナマ病を引き起こすバナナ型フザリウムは、様々な地域で栽培されているバナナに感染し、絶滅に瀕している品種も存在する。そこで、本研究の目的は、バナナに大きな問題を引き起こし続けているFusarium oxysporum(フザリウム)を攻撃する抗菌性ペプチドの候補を見出すことに成功した。
