| 英文摘要 | The mitochondrial DNAs (mtDNAs) from 30 pig breeds (29 Chinese native breeds and 1 European breed) and wild boars were investigated for restriction fragment length polymorphisms (RFLPs) to determine the phylogenetic relationships and genetic diversity among pig breeds and wild boars. Of the 24 enzymes used, 8 (AvaI, BclI, BglII, EcoRI, EcoRV, ScaI, StuI, and XbaI) detected polymorphisms. By combining the cleavage patterns for each enzyme, 108 individuals were sorted into eight mtDNA mitotypes. There are two haplotype lineages in domestic pigs, i.e., Chinese and European lineages. The pairwise nucleotide sequence divergence was calculated to be 0.56% between Chinese pigs and European pigs, suggesting that they might have diverged from a common ancestor approximately 280,000 years ago. The wild boars showed more extensive genetic variation, four mitotypes were detected in six wild boars. In addition, one of the Zhejiang wild boars was found to share the same mitotype with Chinese native pigs. A UPGMA tree based on genetic distance among mitotypes indicated that mtDNAs of Chinese pigs and European pigs are clearly divided into two clusters, and Chinese wild boars are more closely related to the Chinese pigs. Our results provide molecular evidence to support the previous hypothesis that pigs may be derived from two maternal origins, Asian and European wild boars. Chinese native pig breeds may have a single origin. |
