title: Gene rearrangements in the mitochondrial genome of Cynoglossus bilineatus (Pleuronectiformes: Cynoglossidae).
abstract: Cynoglossus bilineatus (Cynoglossidae, Soleoidei) is characterized by both eyes on the left side of the body and with a rounded snout and a short rostral hook. Here we first report the mitogenome of this tongue sole, which is 16,454 bp in length, and gene rearrangements have been observed. Particularly, the tRNA-Gln gene encoded by the light strand (L-strand) has translocated to the heavy strand (H-strand), along with the tRNA-Ile gene shuffling. In addition, the putative control region has translocated downstream to a position between the ND1 and tRNA-Gln genes, leaving a 26-bp intergenic spacer in its original position. However, the arrangement of the rest genes is identical to that of the typical teleost. This result could contribute to a better understanding the molecular mechanisms of gene rearrangement in fish mitogenome as well as phylogenetic study of Cynoglossidae and Pleuronectiformes.
