Complete mitochondrial genome of cocktail wrasse Pteragogus flagellifer

Abstract

We determined the complete mitochondrial (mt) sequence of the Cocktail wrasse, Pteragogus flagellifer. The mt genome is 16,807 bp long and consists of 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and two noncoding regions. All its mt protein-coding genes begin with an ATG start codon except for CO1, which begins with GTG. The order of the mt genes is largely identical to that of typical vertebrates, although the position of the TMF-regulated nuclear protein (trnP) is unique among known Labridae gene arrangements. The phylogenetic tree of Labridae showed that P. flagellifer is relatively close to Pseudolabrus.
