The complete mitochondrial genome sequence of Tylototriton taliangensis (Amphibia: Caudata).

Tylototriton taliangensis was listed as a Near Threatened amphibian in IUCN red list. In this study, we sequenced the complete mitochondrial (mt) genome of this species (GenBank: KP979646) and found it contains 16,265 base pairs, which encode 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNA), 2 ribosomal RNA genes (rRNA) and 1 control region (CR). We also found that almost all PCGs and tRNA genes are located on the H-strand, except for ND6 subunit gene and eight tRNA genes, which were distributed on the L-strand. The PCGs used "ATG" and "GTG" as the start codon, while used four types of stop codons. Almost all tRNA genes were folded into typical cloverleaf secondary structures. The L-strand replication origin (OL) and a non-coding region were also found. The new mitogenomic phylogenetic tree confirms the reciprocally monophyly of the genus Tylototriton, Echinotriton and Pleurodeles with high bootstrap value. The present study will provide information for future studies on the conservation genetics and phylogeny of this species and its relatives.
