摘要

中国家猪品种遗传资源丰富，但缺乏明确的地理专一性和遗传结构信息。在这项研究中，我们分析了359个线粒体D-loop序列，其中86个序列来自中国家猪，其余序列从GenBank下载。单倍型和核苷酸多样性指数分别为0.467±0.132(杜洛克)~ 1.000±0.500(泰国、朝鲜和柬埔寨)和0.00067±0.00019(杜洛克)~ 0.02000±0.01000(泰国)。邻居连接树显示个体猪中有两个分支，其中一个中国家养品种在几个品种中不连续分布。网络数据表明，中国家猪的基因库可能与中国、日本和其他一些东南亚野猪有亲缘关系。

Genetic diversity of mitochondrial DNA D-loop in wild and domestic pigs (Sus scrofa) in East Asia

Chinese domestic pig breeds have abundant genetic resources, but definite information about the geographic specificity and genetic structure is lacking. In this study, we analysed 359 mitochondrial D-loop sequences, including 86 sequences from Chinese domestic pigs and the rest downloaded from GenBank. The haplotype and nucleotide diversity indices ranged from 0.467 ±0.132 (Duroc) to 1.000 ±0.500 (Thailand, North Korea and Cambodia) and 0.00067 ±0.00019 (Duroc) to 0.02000 ±0.01000 (Thailand), respectively. The neighbour-joining tree revealed two clads in the individual pigs, with a Chinese domestic breed distributed discontinuously among several breeds. The network data indicated that the gene pools of Chinese domestic pigs are likely related to Chinese, Japanese and some other Southeast Asian wild boars.
