The complete F-type mitochondrial genome of threatened Chinese freshwater mussel Solenaia oleivora (Bivalvia: Unionidae: Gonideinae)

Abstract

The freshwater mussel Solenaia oleivora is considered threatened due to anthropogenic habitat modification and pollution. The complete F-type mitochondrial genome (mitogenome) of S. oleivora was first determined (GenBank accession no. KF296320). The length of this mitogenome is 16,392 bp with an AT content of 59.9%. There are 37 typical animal mitochondrial genes and a putative control region. Within the control region, 5 tandem repeats of a 106 bp element were identified. The gene order rearrangement of cox2-rrnS in F-type mitogenome compared to that of other freshwater mussels, is not unique for S. oleivora, but is shared with all other available freshwater mussels in the subfamily Gonideinae. The complete mitogenome can provide a basic data for the further studies on molecular taxonomy, phylogenetic analyses and conservation genetics.
