Abstract

: This communication is the first report on mitochondrial lineage of Andaman wild boar based on mitochondrial D-loop sequence information. Andaman wild boar is an endangered endemic species of Andaman & Nicobar archipelago. D-loop sequence information of Andaman wild boar (MT024628-29) was compared with endemic Sus species of Southeast Asia, Eurasian clades of wild boar and Indian wild boar characterized from mainland of India. Phylogenetic analysis, median joining (MJ) network and genetic distance analysis revealed that Andaman wild boar belonged to S. scrofa . Earlier literature suggested that Eurasian wild boars are clustered into five clades. Our analysis revealed that Andaman wild boar had the least genetic distance with Asiatic clade and had the highest genetic distance with the Italian clade. This data was further supported by pairwise Fst. Phylogenetic analysis, MJ network and PCA plot could identify genetic affinity of Andaman wild boar with Asiatic clade of wild boar. Interestingly, Andaman wild boar clustered with wild boars found in two specified geographical regions of India. This may be justified as leftover of cultural diffusion during c . 500/ 400 BCE.

安达曼群岛的一种濒临灭绝的特有物种——安达曼野猪(毛平猪)的母系

：本通讯是首次基于线粒体D环序列信息对安达曼野猪线粒体谱系的报道。安达曼野猪是安达曼和尼科巴群岛的濒危特有物种。将安达曼野猪（MT024628-29）的D环序列信息与东南亚特有的苏斯种、欧亚野猪分支和印度大陆特有的印度野猪进行了比较。系统发育分析、MJ网络和遗传距离分析表明，安达曼野猪属于S.scrofa。早期文献表明，欧亚野猪分为五个分支。我们的分析表明，安达曼野猪与亚洲分支的遗传距离最小，与意大利分支的遗传间距最高。这一数据得到了成对Fst的进一步支持。系统发育分析、MJ网络和PCA图谱可以鉴定安达曼野猪与亚洲野猪分支的亲缘关系。有趣的是，安达曼野猪与在印度两个特定地理区域发现的野猪聚在一起。这可能被认为是c时期文化传播的残余。500/400 BCE。
