Abstract:
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.
