Abstract

A genetic analysis using starch gel electrophoresis was performed to clarify the degrees of genetic differentiation and the phylogenetic relationships among four species of the genus Corbicula (Bivalvia, Corbiculidae). The average genetic similarity coefficients among the populations of each species on C. fluminea, C. leana and C. colorata were very closed (Rogers' S$\geq$0.970), whereas the other C. japonica was separated into two genetic groups (S=0.873) with distinct allelic difference at the Gpl locus. Thuefore additional taxonomic studies are needed on this species. On the other hand, these four species were well distinguished from each other genetically with distinct allelic differences at 4 to 9 loci. The genetic similarity coefficients (S) between C. leana and C. colorata, C. fluminea and C. leana, and C. fluminea and C. colorata were 0.737, 0.689, and 0.594, respectively. In particular, the average genetic similarity coefficients between these three species (inhabiting in freshwater) and the other C. japonica (inhabiting in brackishwater) were notably lower (S=0.370).

남한의 15개 지역에서 채집된 재첩속(Corbicula) 4종간의 유전적 분화수준 및 계통 유연관계를 규명하고자 전기영동을 이용한 동위효소 분석을 실시하였다. 이들 4종 중 담수 산인 C. fluminea, C. leana, C. colorata 3종의 종내 집단간 유전적 근연치는 S=0.970 이상 (0.970∼1.000)으로 매우 가깝게 나타났으나 기수산인 C. japonica의 집단들은 Gp-1 유전자 에서 뚜렷한 대립인자 차이를 가지는 2개의 유전적 group으로 분리(S=0.873)되어 이에 대한 추가적인 분류학적 검토가 요구되었다. 각 종간의 유전적 근연치는 C. fluninea와 C. leana 가 S=0.689, C. fluminea와 C. colorata는 S=0.594 그리고 C. leana와 C. colorata는 S=0.737 로 나타나 이들 담수산 3종간의 유전적 차이는 매우 뚜렷하였다. 특히, 기수산인 C. japonica는 담수산 3종과의 평균 유전적 근연치가 S=0.370으로 가장 먼 유전적 근연관계를 나타내었다.
