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

Abstract

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.

The first complete mitochondrial genomes of sawtail surgeonfishes (Acanthuridae: Prionurus)

“… 2007 ; Devadhasan et al. 2016a , 2016b ; Huang et al. 2017 ), with the exception of the genus Prionurus .…”

“…The family comprises six genera and 85 recognized species (Fricke et al 2019), most of which are herbivores that provide important ecosystem functions to reefs and an important link between primary producers and higher trophic levels (Randall 2001;Marshell and Mumby 2015). Mitochondrial genomes for most surgeonfish genera have been sequenced (Yamanoue et al 2007;Devadhasan et al 2016aDevadhasan et al , 2016bHuang et al 2017), with the exception of the genus Prionurus. Here, we report whole mitochondrial genomes for P. biafraensis (Blache and Rossignol 1961) Ludt et al (2019).…”
