Hermaphroditic freshwater mussel Anodonta cygnea does not have supranumerary open reading frames in the mitogenome

Abstract

The complete mitogenome of Anodonta cygnea is 15,613 bp long. This compact, circular molecule contains the set of 37 genes, typical for invertebrate mitogenomes, in the same order and orientation as in maternally inherited genomes of other bivalves from the same subfamily. There are only two unassigned regions longer than 200 bp (266 bp and 274 bp) and no indication of any supranumerary open reading frames.
