摘要
The complete mitochondrial genome of Oreolalax jingdongensis occurring from the southwestern mountains of China was determined. The new complete mitochondrial genome is 17,864 bp in length and contain 13 protein-coding genes, 2 rRNA genes, 23 tRNA genes, and a control region. Different from the typical gene order in most of anuran species, structure of the mitochondrial genome of O. jingdongensis has a tandem duplication of two tRNA-Met genes and rearrangements of several tRNA genes. Phylogenetic relationships was reconstructed base on the sequences of 13 protein-coding genes from the complete mitochondrial genome of 18 representative Megophryidae species using Bayesian inferences and Maximum likelihood approaches, and the results supported the monophyly of this family. This study supplied basic genetic data for further genetic research and conservation of the toad group.
