Abstract
The complete mitochondrial genome of Orinhippus tibetanus, which was collected from the Tibetan Plateau, is reported here. It is 15,611 bp in length and contains 74.2% AT. All O. tibetanus protein-coding sequences except for the cox1 start with a typical ATN codon. The usual termination codons (TAA or TAG) and incomplete stop codons (T or TA) are found from 13 protein-coding genes. All tRNA genes could be folded into the typical cloverleaf secondary structure, except trnS(AGN) lacking of dihydrouridine (D) arm. The sizes of the large and small ribosomal RNA genes are 1317 and 854 bp, respectively. The AT content of the A + T-rich region is 84.8%.
