Abstract

In this work, the mitochondrial genomes for spotted halibut (Verasper variegatus) and barfin flounder (Verasper moseri) were completely sequenced. The entire mitochondrial genome sequences of the spotted halibut and barfin flounder were 17,273 and 17,588 bp in length, respectively. The organization of the two mitochondrial genomes was similar to those reported from other fish mitochondrial genomes containing 37 genes (2 rRNAs, 22 tRNAs and 13 protein-coding genes) and two non-coding regions (control region (CR) and WANCY region). In the CR, the termination associated sequence (ETAS), six central conserved block (CSB-A,B,C,D,E,F), three conserved sequence blocks (CSB1-3) and a region of 61-bp tandem repeat cluster at the end of CSB-3 were identified by similarity comparison with fishes and other vertebrates. The tandem repeat sequences show polymorphism among the different individuals of the two species. The complete mitochondrial genomes of spotted halibut and barfin flounder should be useful for evolutionary studies of flatfishes and other vertebrate species.
