The complete mitochondrial genome of Daurian ground squirrel, Spermophilus dauricus.
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.
