Mitochondrial genome of Pachytriton feii (Urodela: Salamandridae)

In this paper, the complete mitochondrial genome of Pachytriton feii is sequenced and reported for the first time. In our result, the complete mitochondrial genome of P. feii is 16 293 bp in length. Similar to the typical mtDNA of vertebrates, it contained 37 genes (13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes) and 1 non-coding region (D-loop). All the genes in P. feii were distributed on the H-strand, except for the ND6 subunit gene and eight tRNA genes which were encoded on the L-strand. The phylogenetic tree was reconstructed using the Bayesian analysis method and contained two major clades. Among Pachytriton (P. feii, Pachytriton labiatus, and Pachytriton brevipes), Paramesotriton laoensis make up the first lineage.
