The complete mitochondrial genome sequence of Cynoglossus roulei (Pleuronectiformes: Cynoglossidae)

Abstract

The complete mitogenome of Cynoglossus roulei is 16,598 bp in length, containing 37 genes, among them, ND6 and eight tRNA genes are encoded by L-strand and other genes by H-strand, which are as same as those of typical mitogenome in fishes. The gene rearrangement related to one tRNA gene and CR were found, forming the gene order of CR-Gln-Ile-Met, which is the same as that of mitogenomes in all identified Cynoglossus speices. Phylogenetic tree based on 12 protein coding genes, tRNA and rRNA shows that C. roulei has a closer phylogenetic relationship to C. semilaevis.
