Abstract

Mitochondrial genome sequences were first determined and analyzed for a Korean endemic freshwater mussel Nodularia breviconcha (synonym Nodularia douglasiae sinuolatus; Unionidae, Unionida, Bivalvia). The complete mitochondrial genome was 15,741 bp in length, including 13 protein-coding genes (PCGs), 22 tRNA genes, and 2 rRNA genes. The overall GC content of mitochondrial genome for N. breviconcha was 34.3%. Phylogenetic analysis of 18 species within the family Unionidae suggested that Nodularia douglasiae is the most closely related to N. breviconcha. Our study will provide baseline, but important information for future research on ecological and genetic/genomic characteristics of this species.
