Abstract

The complete mitochondrial genome of the clam Corbicula japonica is 17,432 bp in length. The sequence consists of 13 protein-coding, 2 ribosomal RNAs, and 22 transfer RNA genes (GenBank accession no. MZ895053). The proportion of base-pairs in C. japonica are A + T (70.5%) and G + C (29.5%). Phylogenetic analysis reveal C. japonica to be sister species to C. fluminea within the monophyletic genus Corbicula, with high support. This study is helpful to the classification of the brackish water clam C. japonica, which is difficult to identify during early development owing to variation of shell morphology.

Keywords: Corbicula; Mitochondrial genome.
