The Père David's Vole, Eothenomys melanogaster belongs to subfamily Arvicolinae. It is widespread in south China, and ranges into northern Southeast Asia. In this study, the complete mitochondrial genome sequence of Eothenomys melanogaster was determined. The mitogenome is 16,331 base pairs in length. The nucleotide sequence data of 12 heavy-strand protein-coding genes of E. melanogaster and other 17 rodents were used for phylogenetic analyses. Tree constructed using Bayesian phylogenetic methods demonstrated that E. melanogaster as a sister to E. chinensis, was clustered in subfamily Arvicolinae. The monophyly of the genus Eothenomys was supported as well with Eothenomys sister to the genus Myodes.
大卫氏田鼠(Eothenomys melanogaster)属于田鼠亚科。它在中国南方广泛分布,并延伸至东南亚北部。在本研究中,测定了大卫氏田鼠的完整线粒体基因组序列。该线粒体基因组长度为16331个碱基对。利用大卫氏田鼠12个重链蛋白编码基因的核苷酸序列数据以及其他17种啮齿动物的数据进行系统发育分析。采用贝叶斯系统发育方法构建的树状图表明,大卫氏田鼠与中华田鼠(E. chinensis)为姐妹关系,聚类在田鼠亚科中。支持了田鼠属的单系性,田鼠属与林姬鼠属(Myodes)为姐妹关系。
