The complete mitochondrial genomes of Cynomys leucurus and C. ludovicianus (Rodentia: Sciuridae)

Abstract

The mitochondrial genomes of the white - tailed praire dog Cynomys leucurus and black-tailed prairie dog C. ludovicianus (Rodentia: Sciuridae) are circular molecules of 16,454 bp and 16,466 bp in length, respectively, containing 37 genes as in other Rodentia species. The A + T content of the overall base composition of the H-strand is 63.0% and 62.6% for C. leucurus and C. ludovicianus, respectively. The control region of the C. leucurus and C. ludovicianus mt genome is 1012 bp in length, and the A + T content of this region is 63.5% and 62.0%, respectively. Nucleotide sequence divergence of the mt genome (p distance) between C. leucurus and C. ludovicianus was 4.0%.
