Abstract
The complete sequence of mitochondrial DNA of a bottom skate, Bathyraja bergi wassequenced as being circular molecules of 16,780 bp including 2 rRNAs, 22 tRNAs, 13protein coding genes (PCGs) and an AT-rich control region. The organization of thePCGs is the same as that found in other Rajidae species. The nucleotide of L-strand iscomposed of 32.1% A 20.5% C 34.0% T and 13.4% G with a bias toward A+T slightly.Twelve of 13 PCGs are initiated by the ATG codon while COX1 starts with GTG. OnlyND4 harbors the incomplete termination codon, TA. All tRNA genes have a typicalclover-leaf structure of mitochondrial tRNA with the exception of tRNASerAGY which hasa reduced DHU arm.This mitogenome is the first report for a species of the genus Bathyraja and providinga valuable resource of genetic information for understanding the phylogenetic relationshipsand the evolution of the genus Bathyraja as well as the family, Rajidaeon of thePCGs is the same as that found in other Rajidae species.
