Complete mitochondrial genome of marine Petrale sole Eopsetta jordani (Pleuronectiformes: Pleuronectidae) flatfish

Abstract

Petrale sole Eopsetta jordani (Pleuronectiformes: Pleuronectidae) is a species of flounder, found in the northeastern Pacific Ocean and the Bering Sea of the United States and Canada. The complete mitochondrial DNA (mtDNA) of E. jordani has 16,483 bp with an overall A + T content of 61% and consists of 2 ribosomal RNA (rRNA) genes, 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, and a non-coding control region. It has incomplete stop codon genes in ND2, COII, ATPase6, COIII, ND3, and ND4. Phylogenetic analysis indicated that E. jordani is not monophyletic with cogeneric Eopsetta grigorjewi and is separated from other species in the same family by a large distance. Present study results provide useful data for further research on genetic diversity and evolution of the Eopsetta and the Pleuronectidae.
