| Outline of Final Research Achievements |
The annual yield loss caused by parasitic plants in Orobanchaceae was estimated as more than 1 billion USD. To understand the molecular mechanisms of plant parasitism, we have employed molecular genetic approaches; isolate mutants that have defects in parasitism and identify the causative genes for the mutants. We used a Japanese native parasitic plant Phtheirospermum japonicum as a model plant, and identify mutants that fail to invade host plants. Next generation sequencing analysis and subsequent genome comparison with wild type successfully identified the mutant causative genes.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、ハマウツボ科寄生植物の宿主侵入に植物ホルモンエチレンのシグナル伝達が重要なことを明らかにした。エチレンは農業寄生雑草ストライガの発芽誘導物質としても知られており、本発見によってエチレンやエチレン阻害剤を用いた新たな防除法の開発につながると期待できる。また、寄生植物の変異体からの遺伝子同定法を確立したことで、今後、規制に必須な遺伝子の同定がさらに進むと期待できる。
