To study the ancestry and phylogenetic relationships of native Korean dog breeds to other Asian dog populations, we analyzed nucleotide variations in whole-genome sequences of 205 canid individuals. Sapsaree, Northern Chinese indigenous dog, and Tibetan Mastiff were largely related to West Eurasian ancestry. Jindo, Donggyeongi, Shiba, Southern Chinese indigenous (SCHI), Vietnamese indigenous dogs (VIET), and Indonesian indigenous dogs were related to Southeast and East Asian ancestry. Among East Asian dog breeds, Sapsaree presented the highest haplotype sharing with German Shepherds, indicating ancient admixture of European ancestry to modern East Asian dog breeds. SCHI showed greater haplotype sharing with New Guinea singing dogs, VIET, and Jindo than with other Asian breeds. The predicted divergence time of East Asian populations from their common ancestor was approximately 2,000 to 11,000 years ago. Our results expand understanding of the genetic history of dogs in the Korean peninsula to the Asian continent and Oceanic region.
为了研究韩国本土犬种与其他亚洲犬类群体的祖先关系和系统发育关系，我们分析了205个犬科个体全基因组序列中的核苷酸变异。沙皮犬、中国北方本土犬和藏獒在很大程度上与西欧亚血统有关。珍岛犬、东谷犬、柴犬、中国南方本土犬、越南本土犬和印度尼西亚本土犬与东南亚和东亚血统有关。在东亚犬种中，沙皮犬与德国牧羊犬的单倍型共享率最高，表明欧洲血统在现代东亚犬种中存在古老的混合。中国南方本土犬与新几内亚歌唱犬、越南本土犬和珍岛犬的单倍型共享率高于其他亚洲犬种。东亚群体与其共同祖先的预测分化时间约为2000至11000年前。我们的研究结果将对朝鲜半岛犬类遗传历史的认识扩展到了亚洲大陆和大洋洲地区。
