Abstract

We report mitochondrial cytochrome b (cyt b) genes from greenling Hexagrammos otakii (Jordan et Starks) and spotty belly greenling, H. agrammus (Temminck et Schlegel) within Hexagrammidae, two species of aquaculture importance. Of 489 bp of the cytochrome b gene, a little variation occurred between species (96% similarity). The pairwise distance (0.0342) between greenling and spotty belly greenling in term of the Neighbor-joining method indicated that two species was close in molecular phylogenetic consideration. These findings are applicable to aquaculture, fisheries genetics and molecular phylogenetics in the genus Hexagrammos.

본 연구는 쥐노래미과(Hexagrammidae)에 속하고 양식산업에서 중요한 위치를 차지하고 있는 노래미, Hexagrammos otakii(Jordan et Starks)와 쥐노래미, H. agrammus(Temminck et Schlegel)의 미토콘드리아 cytochrome b(cyt b)유전자의 염기서열을 서로 비교 분석하였다. 총 489 bp크기의 cyt b 염기서열에서 종간의 변이는 거의 없었다(96%의 유사성).Neighbor-joining방법에 의한 노래미와 쥐노래미에서의 0.0342인 pairwise distance는 두 종이 분자계통유전학적으로 유사함을 시사한다. 이러한 연구 결과들은 쥐노래미(Hexagrammos)속을 대상으로 한 양식, 수산유전학 및 분자계통학 분야에 적용 가능할 것이다.
