초록

돼지 6품종(Landrace, Duroc, Large White, 한국재래돼지, Berkshire, Hampshire)을 대상으로 기존에 보고된 서열을 바탕으로 제작한 primer를 이용하여 mtDNA D-loop 전체영역을 증폭하였다. 증폭된 PCR product를 cloning 및 DNA sequencing, 다중염기서열비교를 통하여 분석한 결과, mtDNA에서 heteroplasmy가 나타나는 D-loop 내 tandem repeat region 이후에 11-bp 중복이 존재하는 것을 확인하였다. 이런 중복현상은 일본재래돼지와 Duroc에서 보고되었지만, 이를 이용한 돼지 품종별 중복현상의 빈도 및 분포에 관한 연구는 이루어져있지 않다. 품종별 11-bp 중복현상을 분석하기 위해서 6품종을 대상으로 중복지역을 포함한 약 150 bp 절편을 증폭하였으며, PAGE 방법을 통하여 분석하였다. 그 결과 본 연구에서 사용한 품종들 중 모든 Large White에서 중복현상이 발생하는 것을 확인하였으며, Duroc인 경우 11.2% (9/80)에서 중복현상이 확인되었다. 반면에 Landrace, 한국재래돼지, Berkshire 및 Hampshire에서는 전혀 발견되지 않았다. 이런 결과로서, 11-bp 중복현상의 분석은 현재 구별이 불가능한 Landrace와 Large White를 구별할 수 있는 유용한 DNA marker로서 사용이 가능할 것이다.
