The Duke of Bedford's vole ( Thomas 1911) is distributed only at the border areas of the Sichuan and Gansu Provinces, China. In this study, the first complete mitochondrial genome of is generated and characterized. The assembled genome is 16,262 base pairs in length and the base compositions present clearly the A-T bias (60.84%). Its genetic constitution and arrangement are consistent with the taxon of the voles, including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 2 main non-coding regions, D-loop region and O region. This mitochondrial genome will be a significant supplement for the genus and whole mitogenome phylogenetic analysis provided insights into further evolutionary research of the subfamily Arvicolinae.
贝德福德田鼠（托马斯，1911年）仅分布于中国四川省和甘肃省的边境地区。在本研究中，首次获得并对其完整的线粒体基因组进行了特征分析。组装后的基因组长度为16262个碱基对，碱基组成明显呈现A-T偏向性（60.84%）。其基因构成和排列与田鼠类群一致，包括13个蛋白质编码基因、22个tRNA基因、2个rRNA基因以及2个主要的非编码区域，即D-loop区域和O区域。该线粒体基因组将为该属提供重要补充，并且完整的线粒体基因组系统发育分析为田鼠亚科的进一步进化研究提供了见解。
