Complete F mitochondrial genomes of two freshwater mussels from the Lake Biwa system in Japan: Beringiana fukuharai and Sinanodonta tumens

We determined the complete mitochondrial sequences of female-transmitted (F) mitogenomes of six unionid specimens from the Lake Biwa system, Japan. Their gene contents and orders agreed with those of the typical F mitogenome of freshwater mussels. Molecular phylogenetic analysis using fifteen previously identified partial COI and 12 (six previously identified and six newly determined) whole mitogenome sequences revealed that five of the six mitogenomes (LC592401, LC592402, LC592403, LC592408, and LC592410) were those of Beringiana fukuharai, while the remaining one (LC592406) was Sinanodonta tumens.

Automated summary

The complete mitochondrial sequences of female-transmitted mitogenomes of six unionid specimens from the Lake Biwa system in Japan were determined. Analysis showed that five of the specimens belonged to Beringiana fukuharai, while one belonged to Sinanodonta tumens. The gene contents and orders of these mitogenomes were in agreement with those of typical freshwater mussel mitogenomes.
