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

Abstract

Cynoglossidae (tongue soles) mitogenomes have been found to be translocated in their control region and a tRNA gene inversed, but no gene rearrangement in Soleidae, the closest family to Cynoglossidae, has been detected. In order to explore whether or not mitogenomes of tongue soles bear other gene-rearrangement types, we determined another tongue sole mitogenome of Cynoglossus sinicus. The total length of this mitogenome is 16,478 bp, and the tRNA-Gln gene is translocated from the light strand (L-strand) to the heavy strand (H-strand), accompanied by shuffling of tRNA-Gln, Ile and Met genes with a 143 bp intergenic spacer between tRNA-Gln and Ile. The control region (CR) might translocate to the position between the ND1 and the tRNA-Gln genes. The order of the rest genes is identical to that of the typical fish.
