The complete mitochondrial genomes of two endangered bitterling Acheilognathus tabira tohokuensis and A. tabira erythropterus (Cyprinidae, Acheilognathinae)

Abstract

Acheilognathus tabira (tabira bitterling) comprises of 5 subspecies, all of which are endangered. In this study, the mitochondrial genome (mitogenome) of the 2 subspecies, A. tabira tohokuensis and A. tabira erythropterus, whose mitogenomes have not been reported previously, was determined. The total lengths of A. tabira tohokuensis and A. tabira erythropterus mitogenomes were 16,774 bp and 16,770 bp, respectively, and were noted as slightly AT-rich. Phylogenetic analysis revealed that these 2 subspecies of A. tabira were the most closely related, out of the 5 subspecies. The deciphered mitogenomes would be useful for conservation and evolutionary studies.
