The complete mitochondrial genome and phylogenetic analysis of Sinocyclocheilus angularis (Cypriniformes: Cyprinidae).

ABSTRACT: This is the first study to determine the complete mitochondrial genome of Sinocyclocheilus angularis, which is an endemic cavefish native to the Karst region of the Yunnan-Guizhou Plateau. The complete mitochondrial genome size of S. angularis was 16,586 bp, and it consisted of a control region, 13 protein-coding genes, 22 transfer RNA genes, and 2 ribosomal RNA genes. The base composition of the mitogenome was 25.14% A, 32.45% T, 27.10% G, and 15.31% C, with an overall GC content of 42.42%. Phylogenetic analysis revealed that all Sinocyclocheilus were clustered into one strong clade and S. angularis was very closely related to S. bicornutus. It will provide an essential genetic tool for the further evolutionary studies and conservation of genus Sinocyclocheilus.
