Abstract
The complete sequence of mitochondrial DNA of a Kwangtung skate, Dipturus kwangtungensis was determined as being a circular molecules of 16, 912 bp including 2 rRNA, 22 tRNA, 13 protein coding genes (PCGs), and a control region. The arrangment of the PCGs is the same as that found in other Rajidae species. The nucleotide of L-strand which encodes most of the proteins is composed of 30.2% A, 27.4% C, 28.2% T, and 14.2% G with a bias toward A+T slightly. Twelve of 13 PCGs are initiated by the ATG codon while COX1 starts with GTG. Only ND4 harbors the incomplete termination codon, TA. All tRNA genes have a typical clover-leaf structure of mitochondrial tRNA with the exception of tRNASerAGY which has a reduced DHU arm. This mitogenome is the first report for a species of the genus Dipturus which will become an important source of information on the phylogenetic relationship and the evolution of the genus Dipturus within the family, Rajidae.ent of the PCGs is the same as that found in other Rajidae species.
