We report the complete mitochondrial genome for the , a typical subterranean rodent species and endemic in China. The resulting mitogenome is 16,355 bases in size, containing 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and 1 noncoding control region (D-loop). The base compositions present highly biased toward A + T nucleotides. Moreover, twelve of all 13 PCGs initiated with ATN start codon, whereas began with GTG start codon. Stop codons in 13 PCGs were all typical types except incomplete stop codon T for . We further provide a Maximum Likelihood phylogenetic tree showing relationships among and other common subterranean rodents in family Spalacidae.
我们报告了中华鼢鼠（一种典型的地下啮齿动物物种且为中国特有）的完整线粒体基因组。所得线粒体基因组大小为16355个碱基，包含13个蛋白质编码基因（PCGs）、2个核糖体RNA（rRNA）基因、22个转运RNA（tRNA）基因和1个非编码控制区（D-loop）。碱基组成严重偏向于A+T核苷酸。此外，13个PCGs中的12个以ATN起始密码子开始，而ND2以GTG起始密码子开始。13个PCGs中的终止密码子均为典型类型，除了COX1的不完全终止密码子T。我们还提供了一个最大似然系统发育树，展示了中华鼢鼠与鼹形鼠科其他常见地下啮齿动物之间的关系。
