Abstract

To analyze the population genetic structure of the oyster Crassostrea gigas Thunberg, 34 specimens werecollected from Gamak bay in March, 2007. Total genomic DNA was extracted from each sample and PCR was performed to identify haplotypes of oyster by using HCO2918 and LCO1491 primers. Four kinds of haplotypes (CR1, CR2, CR3, and CR4) were identified. Among these group, CR3 showed the highest relative frequency at 73% than any other of haplotypes. On the basis of hierarchical genetic structure, the population of Gamak showed a higher genetic relationship with Namhae, but the genetic distance between southern and western coasts was negative and no statistical significance was found (p>0.05). Consequently, the oyster from Korea coast is determined to be both homogenous and large.

본 연구는 2007년 3월 가막만에서 양식하고 있는 참굴 34마리를 대상으로 미토콘드리아COI gene 염기서열분석을 통하여 유전자 집단을 조사했다. PCR 증폭에 사용된 primer는 HCO2918과 LCO1491로 product는 658 bp였다. 유전자 배열 결과 가막만 참굴 집단에서 CR1, CR2, CR3, CR4 4개의 haplotype이 나타났다. 그 중 CR3 haplotype이 73% 발생되어 가장 높은 빈도율을 보였다. 계층구조에서도 가막산 참굴은 남해안산과 유전적 유연관계를 보이나, 유전적 거리는 남해안 및 서해안과도 마이너스 값을 보이며 통계적으로도 유전적으로 하나의 집단을 형성하고 있음을 알 수 있다.
