The mitochondrial genome sequence of Daurian ground squirrel, Spermophilus dauricus, is determined and described for the first time in this study. The genome was a total of 16 512 bp in length and had a base composition of A (32.08%), G (12.53%), C (24.35%), and T (31.04%), indicating that the percentage of A + T (63.12%) is higher than G + C (36.88%). Similar to those reported from other animal mitochondrial genomes, it possessed a typically conserved structure, including 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and 1 control region (D-loop). Most of these genes were found to locate on the H-strand except for the ND6 gene and 8 tRNA genes. The phylogenetic analysis showed Spermophilus dauricus formed the sister group to the Pteromyini tribe. This mitochondrial genome sequence would supply useful genetic resources to uncover Sciuridae family evolution.
本研究首次测定并描述了达乌尔黄鼠（学名：Spermophilus dauricus）的线粒体基因组序列。该基因组全长16512bp，碱基组成为A（32.08%）、G（12.53%）、C（24.35%）和T（31.04%），表明A+T（63.12%）的百分比高于G+C（36.88%）。与其他动物线粒体基因组报道的情况类似，它具有典型的保守结构，包括13个蛋白质编码基因、22个转运RNA基因、2个核糖体RNA基因和1个控制区（D环）。除ND6基因和8个tRNA基因外，这些基因大多位于重链上。系统发育分析表明，达乌尔黄鼠形成了鼯鼠族的姐妹群。该线粒体基因组序列将为揭示松鼠科的进化提供有用的遗传资源。
