The complete mitochondrial genome sequence of Jinshaia abbreviata (Cypriniformes, Balitoridae)

Abstract

Jinshaia abbreviata, belonging to the family Balitoridae in Cypriniformes, is endemic to the Upper Yangtze River with most population distributed in the Jinsha River. In this study, the complete mitochondrial genome of J. abbreviata was sequenced with its structure analyzed. The mitochondrial genome of J. abbreviata is similar to those of the typical vertebrates, 16,567 bp in length, including 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and one non-coding control region (D-loop). The D-loop of J. abbreviata was characterized by one termination-associated sequence with two pair of motifs and six conserved sequence blocks (CSB-F, CSB-E, CSB-D, and CSB I-III). The mitogenome sequence of J. abbreviata could contribute to estimate the phylogenetic relationship of the Balitoridae. And further investigations with more Jinshaia species and individuals included need to be performed to better understand the speciation process and evolutionary history of the genus Jinshaia.
