Outline of Final Research Achievements

An ultraviolet-irradiated strain of Paraboeremia sp. Lsl3, a Lycopodiaceae plant-derived endophytic fungus was successfully prepared, and the potential production ability of huperzine A, a candidate natural product of Alzheimer’s disease treatment, has been proved. Furthermore, a facile gene manipulation system of Lsl3 strain was established, and the whole genome sequence has been completed.

Academic Significance and Societal Importance of the Research Achievements

アルツハイマー病改善薬候補であるhuperzine Aは、植物により生産される有効成分であることで知られるが、その生産メカニズムはいまだ明らかにされていない。本研究では、新種の植物内生糸状菌がhuperzine Aを潜在的に生産する能力を持つことを証明し、同菌の遺伝子実験システムを整備することで、生合成機構の解明に向けて大きく前進することができた。このことは、huperzine Aの大量生産システム構築への足がかりにもなり、医薬品開発における新しい供給戦略となることが期待される。
