Abstract
The complete mitogenome sequence of Pseudohynobius jinfo, which is endemic to China, is sequenced in the present study. The genome was 16,393 bp in length, including 13 typical vertebrate protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 1 non-coding control region. Except for ND6 and eight tRNA genes, all other mitochondrial genes were encoded on the heavy strand. The gene order and composition of P. jinfo was similar to that of the most Hynobiidae. Seven genes (ND1, ND2, COII, COIII, ND3, ND4 and Cytb) had an incomplete stop codon. Base composition of the genome was A (33.6%), T (31.8%), C (20.6%) and G (14.1%) with an A + T-rich feature (65.4%) as that of other vertebrate mitochondrial genomes. There was a long non-coding region (126 bp) between tRNA-Thr and tRNA-Pro genes.
