| Outline of Final Research Achievements |
Mechanism of resistance to acetyl-CoA carboxylase inhibiting herbicides in multiple-herbicide resistant paddy weed, Echinochloa phyllpogon, were investigated. Our research revealed that the resistance is mainly caused by the identical herbicide metabolizing enzymes that had previously been identified to cause resistance to acetolactate synthase inhibiting herbicides.

| Academic Significance and Societal Importance of the Research Achievements |
除草剤の解毒代謝による抵抗性を獲得した雑草は多様な除草剤に抵抗性を示すことが多く、作物生産上の大きな脅威とされている。しかしそのメカニズムについてはあらゆる雑草において分かっていなかった。本研究では多剤抵抗性に関わる遺伝子を明らかにすることに成功した。本研究は抵抗性雑草の防除において有意義な知見となる。
