The complete mitochondrial genome of Saxidomus purpuratus (Veneroida: Veneridae).

In this study, the complete mitochondrial genome of Saxidomus purpuratus is determined, which is the first complete mitochondrial genome in the genus Saxidomus. The genome was of 19 637 bp in length, including 2 rRNAs, 22 tRNAs and 12 protein-coding genes with the order of ND3 and ND5 reversed. Maximum likelihood tree based on nucleotide sequences of 12 mitochondrial PCGs was constructed, in which S. purpuratus was clustered with 3 Meretrix species. The results are expected to provide useful data for species identification and further studies of the genus Saxidomus.
