The complete mitochondrial genome of Eleotris oxycephala (Perciformes: Eleotridae)

Abstract

In the present study, we obtained the complete mitochondrial genome sequence of Eleotris oxycephala, which was 16 527 bp in length. This genome consisted of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and a putative control region. Of the 37 genes, 28 were encoded by heavy strand, while nine were encoded by light strand. The overall base composition of this mitogenome was 28.21% for A, 16.81% for G, 24.75% for T, 30.23% for C, respectively, with a slight higher A + T content (52.96%). The phylogenetic analysis based on 13 concatenated protein-coding genes suggested that E. oxycephala as a sister species to Eleotris acanthopoma was clustered in family Eleotridae. This complete mitochondrial genome sequence of E. oxycephala should be helpful for the studies on population genetic structure, molecular evolution and phylogeny of E. oxycephala and related species.
