Sequencing and analysis of the complete mitochondrial genome of the surgeon fish Acanthurus leucosternon BENNETT 1833 (Perciformes: acanthuridae) with phylogenetic consideration.

In this study, the complete mitochondrial genome of Acanthurus leucosternon was determined. The genome is circular, double-stranded DNA molecule with 16,434 bp in length (EU 136032). The structure, gene organization, and gene order is similar as in other vertebrates. The overall base composition is A (29.29%), C (28.53%), T (26.37%), G (15.81%), and with 44.33% G + C content. Overlapping observed between contiguous genes is encoded in the opposite strands. The two 12S and 16S rRNA genes consist of 949 and 1690 nucleotides, respectively. Non-coding control region is 754 bp long and origin of replication is located in the WANCY cluster. Conserved domains in the control regions and secondary structures for the OL regions are also predicted. Molecular phylogenetic analysis using Maximum-Likelihood method of A. leucosternon based on the protein-coding gene sequence was also studied.
