Abstract
In this study, the total mitochondrial genome of a freshwater pearl mussel Margaritiana dahurica Middendorff (Eulamellibranchia: Margaritanidae) was first determined. The genome is 16,112 bp in length. It consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 HORF. The overall nucleotide composition of the H-strand of M. dahurica Middendorff mitochondrial genome is A: 37.85%, G: 13.22%, T: 23.74% and C: 25.19%, respectively, with an A + T rich feature (61.59%). These results provide useful information to further study of the molecular systematics, species identification and conservation genetics of M. dahurica Middendorff.
