Abstract:
The entire mitogenome of Tylototriton kweichowensis is 16 727 bp in length. It consists of 13 protein-coding genes (PCGS), 2 ribosomal RNA genes (rRNA), 22 transfer RNA genes (tRNA), and 1 control region (CR). Except for ND6 subunit and 8 tRNA genes are distributed on the L-strand, all the other PCGs and tRNA genes are located on the H-strand. "ATG" and "GTG" are the start codons of the PCGs, "TAA", "AGA", "TA-" and "T--" are the stop codons. Most of the tRNA genes can be folded into typical clover-leaf secondary structure. The genome of T. kweichowensis has two repeat sequences in the cob-noncoding region. Mitogenomic phylogenetic analysis (NJ tree) robustly resolved the genus-level relationship among the three genera Tylototriton, Echinotriton, and Pleurodeles, and which is congruent with the previous molecular phylogeny results.
