Abstract

The complete mitochondrial DNA genome of Sinocyclocheilus xiaotunensis was first reported by next-generation sequencing method. The entire length of mitochondrial genome is 16,588 bp and the nucleotide composition was made up of 32.3% A, 25.0% T, 27.2% C, and 15.5% G, indicating an A + T(57.3%) content is greater than C + G(42.7%). The mitogenome is a circular DNA molecule with a D-loop region and contains 22 transfer RNA (tRNA) genes, two ribosomal RNA(rRNA) genes and 13 protein-coding genes.To provide further info on the conserved sequence block observed in the control region of the mitochondrial genome. This info is critical for future application and determination of taxonomic status of this species.

Keywords: Mitochondrial genome; Sinocyclocheilus xiaotunensis; phylogeny.
