The Complete Mitochondrial Genome of the Fivespot Flounder, <i>Pseudorhombus pentophthalmus</i> (Pleuronectiformes: Paralichthyidae), from Korea and Its Phylogenetic Analysis

Abstract

The mitogenome is an important tool for researching the evolution of metazoan animals. However, until now, only few mitochondrial genes of Pseudorhombus pentophthalmus have been reported. Here, we report the complete mitogenome of P. pentophthalmus, assembled using the Illumina platform. The circular mitogenome of P. pentophthalmus is 16,684 bp in length, has a bias A+T content of 52.78%, encodes 37 genes (13 protein-coding genes, 22 tRNA genes, 2 rRNA genes), and has a control region. The overall nucleotide composition was A: 26.56%, T: 26.22%, G: 17.97%, and C: 29.25%. The phylogenetic tree based on the complete mitogenome P. pentophthalmus was shown to be monophyletic with the other Pseudorhombus species and was shown to be on the same branch as P. dupliciocellatus. This research might be useful for future studies on population genetics and evolution analysis.
