초록

돼지 2번 염색체의 육질 관련 양적 경제형질에 관한 연구보고가 몇몇 이루어 지고 있다. 양돈업계에서 DNA 기술을 이용한 염색체 정보를 활용하기 위해 본 연구에서는 13개의 후보 유전자에서 생성된 중합효소연쇄반응(PCR) 생성물을 비교 재서열 함으로써 단일염기변이(SNP) 표지들을 개발했다. 11개의 중합효소연쇄반응 생성물에서 296 bp마다 에서 평균 하나의 SNP, 총 34개의 SNP를 발견하였다. 또한 11개의 SNP에 대한 PCR 제한효소길이 절편길이 다형성(RFLP) 분석을 전개한 후, 이를 대한민국 상업돈 4품종 개체군의 유전자형을 분석하는데 활용하였다. 본 연구는 유용한 단일염기변이를 식별하고 돼지 개체군 내 경제적으로 중요한 특성들과 SNP의 연관성을 확인하는 데 그 목적이 있다.

Several studies reported quantitative trait loci (QTL) for meat quality on porcine chromosome 2. For application of the chromosomal information to pig industry through using DNA technology, single nucleotide polymorphism (SNP) markers are developed by comparative re-sequencing of polymerase chain reaction (PCR) products of 13 candidate genes. A total of 34 SNPs were identified in 11 PCR products, an average of one SNP in every 296 bp.PCR restriction fragment length polymorphism (RFLP) assays were developed for 11 SNPs and used to genotype four commercial pig populations in Korea. The SNP markers were used to map candidate genes in QTL and to clarify the relevance of SNP and quantitative traits.
