Abstract

This study was carried out to define the "Wolla" coat color using 376 Jeju registered horses (white patched 142, solid coat color 234). Three major factors related to the white patches i.e ECA3-inversion for Tobiano, EDNRB 2 bp nucleotide substitution for frame Overo, and the KIT intron 16 single nucleotide polymorphism (SNP) for Sabino types of coat color were analyzed. It was found that out of 142 Jeju horses with white patches that have the genotype for ECA3-inversion (To) 140 horses were +/To heterozygous and 2 horses were To/To homozygous all Jeju horses with white patches had ECA3-inversion allele. However, there was no frame Overo or Sabino allele type in EDNRB and KIT intron 16 SNP in Jeju horses with white patches. As for 234 Jeju horses with a solid coat color, there was no ECA3-inversion allele related to the white patches. Thus, it could be considered that Wolla coat color with white patches in Jeju horses might have come from the Tobiano line in the genetic classification by coat color.

본 연구는 제주마 월라(Wolla) 모색의 백반형태 (Tobiano, frame Overo, sabino)에 대해 유전학적 특성을 구명하고자 수행하였다. 제주마 376두 (월라 142두, 비월라 234두)에 대해 Tobiano 모색 확인을 위해 ECA3-inversion을 분석하였으며, frame Overo 모색은 EDNRB 2-bp 염기치환 상태를 확인하였고, sabino 모색인자형 확인은 KIT intron 16 SNP를 분석하였다. 제주마 월라 모색 개체에서 ECA3-inversion 유전자형이 +/To 이형접합 형태가 140두 (0.986), To/To 동형접합 형태 2두 (0.013)가 나타나 제주마 월라 모두에서 ECA3-inversion이 확인되었다. 반면에 EDNRB와 KIT intron 16 SNP에서는 frame Overo나 sabino 인자는 나타나지 않았다. 제주마 비월라에서는 ECA3-inversion, EDNRB 그리고 KIT intron 16 SNP에서 백반형태와 관련된 인자는 나타나지 않았다. 따라서, 본 연구 결과 제주마 월라(Wolla) 모색은 모색 유전학적 분류에서 Tobiano 모색 유형에 속하는 것으로 사료된다.
