The complete mitochondrial genome of the Dipodomys ordii (Ord's kangaroo rat)

Abstract

Ord's kangaroo rat is a kangaroo rat native to western North America. In this study, we first reported the complete mitochondrial genome of Dipodomys ordii that the first has the complete mitochondrial genome in the genus of Heteromyidae. The mitogenome is a circular molecule of 16 257 bp in length, containing 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and a putative displacement loop region. All protein-coding genes started with a traditional ATN codon and terminated with the mitochondria stop codon (TAA/TAG/AGA) or a single T base. The gene order and composition of mitogenome was similar to that of most other Sciurognathi species and its GC content was 36.73%. Thirteen protein-coding genes of D. ordii together with eight other closely species were used to construct the species phylogenetic tree for verification of the accuracy of new determined mitogenome sequences.
