Abstract
The complete mitochondrial genome of the oriental sole Brachirus orientalis was presented in this study. It is 16,600 bp in length, contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 control region. A total of 28 bp short overlaps and 23 bp non-coding intergenic spacers were found in the mitogenome. The overall base composition of the L-strand is 30.5% A, 28.7% C, 15.2% G and 25.6% T. Two start codons (ATG and GTG) and three stop codons (AGG, TAG and TAA/T) were found in the protein-coding genes. Twenty-two tRNA genes ranged from 66 bp to 75 bp. Since the tRNA-Ser2 lacks the dihydrouridine arm it can not fold into a typical cloverleaf structure. The control region demonstrates the highest A+T content (66.4%) and the lowest G content (11.8%) in the mitogenome.
