Research Abstract |
本研究では、グッピー(Poecilia reticulata)の赤型オプシン遺伝子の維持気候の解明に向けて研究を行った。この研究によってグッピーの視物質遺伝子をすべて同定し、LWS-B, C. D以外の吸収波長を特定した。さらに、沖縄に生息する移入個体を用いて、光感受性を調べる行動実験を行い、LWS-BとLWS-Cから同定できる遺伝子型の違いが緑波長領域の感受性の違いに影響を与えていることが示された。また、グッピー原産地のトリニダッド2集団の個体をLWS-BとLWS-Aの配列を決定し、集団遺伝的解析を行った、Aripo川下流の集団でLWS-Bに関して平衡選択の可能性が示唆された。
