The complete mitochondrial genome of Pseudaesopia japonica (Pleuronectiformes: Soleidae)

Abstract

The Pseudaesopia japonica belongs to family Soleidae in order Pleuronectiformes. In this study, the complete mitochondrial genome of P. japonica was determined and described. The mitogenome is 16 790 bp in length and consists of 13 protein-coding genes, 22 tRNAs, two rRNAs, one control region, and a light strand replication origin. The arrangement of this mitogenome is identical to that of the typical teleost. The overall base composition is 28.5%, 25.7%, 30.3%, and 15.5%, for A, T, C, and G, respectively, with a slight bias on A + T content (54.3%). The maximum likelihood phylogeny tree of 22 flatfishes demonstrated that the species from Zebrias and Aesopia firstly formed a sister group, and then clustered in the same clade with P. japonicas. This study is expected to contributing to the systematic evolution of P. japonicas and further phylogenetic relationship of Soleidae and Pleuronectiformes.
