북방전복 선발육종에 필요한 친자확인 및 가계분석을 효율적으로 실험하기 위하여 microsatellite multiplex PCR 기술을 개발하였다. 개발한 mutiplex PCR 기술은 6개microsatellite locus Hdh145, Hdh512, Hdh1321, Awb017, Awb083 및 Awb098을 한번의 PCR 증폭으로 다중분석이 가능하다. 이 기술은 높은 친자확인 성공률 및 가계분석에 있어서도 모두 멘델의 분리법칙을 따르고 있다. 더욱이대량의 시료처리를 필요로 하는 경우에 있어서도 시간절약 및비용 절감뿐만 아니라 샘플 처리과정의 간소화가 가능하여handling errors를 줄일 수 있다. 따라서 본 연구에서 개발된multiplex PCR은 친자확인, 가계분석, 집단유전학 및 계통분류학 분석에 유용하게 사용할 수 있을 것이라 생각된다.
The multiplex PCR system including six microsatellites from Haliotis discus hannai, consisting of dinucleotide and trinucleotide repeat units, is developed. The six loci were coamplified in a single reaction employing dye-labeled primers. Alleles from these loci were sized using an internal standard by automated sample processing in an ABI3100 Genetic Analyser. Amplified alleles in profiles containing selected microsatellites were typed clearly, providing easily interpretable results. In this results suggest that the presented multiplex PCR system may be a useful tool in a selective breeding program of H. discus hannai in which genetic identification will allow different genotypes to be reared together from fertilization. This should have a great impact as it will make selective breeding more efficient. Moreover, it will be useful in a variety of applications, including strain and hybrid identification, parentage assignment, pedigree reconstruction, estimating genetic diversity and/or inbreeding.
