Characterization of the complete mitochondrial genome of Priacanthus tayenus (Perciformes: Priacanthidae) with phylogenetic consideration

The complete mitochondrial genome of the Priacanthus tayenus was sequenced and analyzed in this study. The mitochondrial genome is 16,866 bp long and consists of 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region. The gene order and the composition of P. tayenus mitochondrial genome were similar to that of most other vertebrates. The nucleotide composition of the light strand in descending order is 30.91% of G, 26. 35% of T, 25.61% of A and 17.13% of C. The NADH dehydrogenase subunit 6 (ND6) and eight tRNA genes were localized in the light strand, and all other mitochondrial genes were encoded on the heavy strand. The phylogenetic analysis by maximum-likelihood (ML) method revealed that the P. tayenus showed the closer relationship to the Sciaenops ocellatus.
