The complete mitochondrial genome of Pelodiscus axenaria (Testudines: Trionychidae)

The complete mitochondrial genome sequence of Pelodiscus axenaria was determined by shotgun sequencing. The total length of mitogenome is 16,593 bp, and contains 13 protein-coding genes, 22 tRNA genes, 2 ribosome RNA genes, and 1 control region. Most of the genes of P. axenaria 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 of P. axenaria and 11 other closely related species was reconstructed. The phylogenetic analyses based on these mitogenomes presented here will be useful for further insights on the evolutionary relationships of Trionychidae.
