초록

본 연구는 제주마 체중 형질과 말의 3번 및 9번 염색체 단일염기변이마커간의 관련성을 분석하기 위해 수행되었다. 본 연구에 사용된 DNA 샘플은 제주특별자치도 축산진흥원에서 등록관리 중인 제주마 320두를 제공받았고, 생체중 자료는 한국마사회에서 시행한 경마에 출주한 제주마의 체중자료를 이용하였다. 기존에 말의 체형관련형질과의관련성이 보고된 바 있는 말의 3번 염색체상에 위치한 BIEC2-808466, BIEC2-808543, BIEC2-808967, BIEC2-809370 단일염기변이마커와 9번 염색체상에 위치한 BIEC2-1105370, BIEC2-1105372, BIEC2-1105377, BIEC2-1105505 and BIEC2-1105840 유전자형을 분석하였다. 관련성 분석을 위한 종속변수는 선형혼합모형을 이용해서 추정한 생체중 육종가를 이용하였다. 관련성 분석결과 6개의 마커(BIEC2-808543, BIEC2-808967, BIEC2-809370, BIEC2-1105370, BIEC2-1105372, and BIEC2-1105377)와 생체중 추정육종가간의 유의성이 인정되었다. 또한, BIEC2-808967과 BIEC2-1105377의 유전자형조합을 구성하여 생체중 추정육종가에 대한 효과를 분석한 결과, 두 마커의 유전자 조합은 생체중 변이에 유의한 효과가 있었다. 본 연구에서 유의성이 인정된 단일염기변이마커들은 제주마의 체중 개량을 위한 선발육종체계의 효율성을 높일 수 있는데 사용될 수 있을 것으로 사료되지만, 이 들 마커효과의 좀더 정확한 추정을 위한 추가의 연구가 필요할 것으로 생각된다.

This study was conducted to investigate the association of single nucleotide polymorphism (SNP) markers on equine chromosomes (ECA) 3 and 9 with body weight in Jeju horses. We used DNA samples and body weight data of 320 horses provided by the Livestock Promotion Agency, Jeju Special Self-Governing Province, and the Korean Racing Association, respectively. We genotyped all the experimental animals using nine SNP markers located on ECA 3 (BIEC2-808466, BIEC2-808543, BIEC2-808967, and BIEC2-809370) and ECA 9 (BIEC2-1105370, BIEC2-1105372, BIEC2-1105377, BIEC21105505, and BIEC2-1105840). These markers were selected due to their effects on body conformation traits in horses. The joint effect of the genotypes of the two SNP markers (BIEC2-808467 and BIEC2-1105377) regarding body weight were also evaluated. The estimated breeding value (EBV) of body weight was obtained as the dependent variable for association analyses using a linear mixed model. Significant associations were detected between SNP markers (BIEC2-808543, BIEC2-808967, BIEC2-809370, BIEC2-1105370, BIEC2-1105372, and BIEC2-1105377) and the body weight EBV. In addition, the joint genotype effect of the BIEC2-808467 and BIEC2-1105377 on the body weight EBV was significant. These results indicate that the SNP markers, which showed their significant effects on body conformation, can be used as genetic markers to improve the efficiency of the selective breeding program for the body weight traits in Jeju horses.
