The complete mitochondrial genome information of Hynobius unisacculus (Amphibia, Caudata, Hynobiidae) and the phylogenetic implication.

ABSTRACT: Hynobius unisacculus is a hynobiid salamander species found only in a limited area at the southernmost part of the Korean Peninsula. Here, we characterized the complete mitochondrial genome of this species that was used to identify the phylogenetic relationship with other Hynobius species. The whole sequence was 16,411?bp and included 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes. The gene arrangement was completely identical to those observed in other Hynobius species. Upon robust phylogenetic tree reconstructed based on 13 protein-coding genes, Hynobius species living on the Korean Peninsula showed close phylogenetic affinity; H. unisacculus and H. quelpaertensis formed a cluster that was the sister to the cluster of H. leechii and H. yangi.
