Outline of Final Research Achievements

During this research period, two species of turbellarians and six species of ribbon worms were described as new. Mitochondrial genomes had been determined for turbellarians representing five of the 11 major free-living platyhelminth subtaxa. In this study, we were able to determine the mitochondrial genome for the first time for a representative of Proseriata, one of the remaining six major turbellarian subtaxa.

Academic Significance and Societal Importance of the Research Achievements

いわゆるバーコード配列を伴って2種の扁形動物と6種の紐形動物を新種として公表したことにより、日本及びその周辺に生息する間隙動物の種多様性に関する知見が増進し、塩基配列情報に基づいた多様性評価法の進展に寄与することが出来た。世界で初めて原順列類のミトコンドリアゲノム塩基配列を決定したことで、扁形動物門のミトコンドリアゲノム進化に関する知見の増大に寄与することが出来た。
