珪藻Chaetoceros tenuissimusに感染するDNA/RNAウイルスの感染特異性と感染を支配する要因

木村 圭1, 外丸 裕司2 1佐賀大学低平地沿岸センター, 2水産総合研究センター瀬戸内海区水産研究所 夏期に沿岸域でブルームを形成する小型浮遊性珪藻C. tenuissimusには、種々のウイルスが感染する。これまでの現場調査から、本珪藻個体群の挙動にウイルスが何らかの影響を与えている事が予想されている。現場における両者の関係を理解するためには量的関係性の調査が必要であるが、さらに質的な関係を明らかにするためには、「珪藻株のウイルス感受性ならびにウイルスの宿主株感染特異性の多様度」、ならびに「ウイルス感染成立可否の支配要因(環境要因やゲノム変異度)」を明らかにす
