Complete mitochondrial genome of Hydrolagus mitsukurii (Jordan & Snyder, 1904).

Holocephali has foreseeable value to help our understanding of vertebrate genome evolution due to its phylogenetic position. In this study, we reported a complete mitochondrial genome of Hydrolagus mitsukurii, a species of holocephalans. The mitochondrial genome is 20,486 bp in length and comprised 13 PCGs, 2 rRNA, 22 tRNA, and 1 control region (D-loop), as well as a long noncoding insertion between tRNAThr and tRNAPro. A phylogenetic tree based on 13 PCGs showed that Hydrolagus mitsukurii was grouped with the members of the family Chimaeridae. Furthermore, the phylogenetic tree further supported the paraphyletic clades of Hydrolagus and Chimera. [ABSTRACT FROM AUTHOR]
