Characterization and phylogenetic analysis of the complete mitochondrial genome of (Hanley 1843) (Bivalvia: Mytiloida: Mytilidae).

We sequenced and assembled the complete mitochondrial genome (mitogenome) sequence of the American brackish water mussel . The mitogenome, reaching 16,302 bp in length, includes 13 protein-coding genes, 2 ribosomal RNA genes, and 23 transfer RNA genes. The overall nucleotide composition of mitogenome was 25.17% A, 41.86% T, 11.83% C, and 21.13% G. The most common start and stop codons were GTG and TAA, respectively. The phylogenetic analysis based on mitogenomes showed that the families Mytilidae, Ostreidae, and Veneridae are a monophyletic group. The phylogenetic position of is sister to and . In this study, mitogenomic sequence data will provide a better understanding for future studies of population genetics, biogeography, and pest surveillance of .
