Mitochondrial Genomes of Six <i>Discogobio</i> Species (Teleostei, Cyprinidae) and Their Phylogenetic Analysis.

ABSTRACT: Discogobio is an important small freshwater economic fish in Southwestern China. In this study, we determined the complete mitochondrial genome (mitogenome) sequences of six Discogobio species by conventional overlapping PCR and Sanger sequencing. The mitogenomes were 16,591-16,605 bp in length and contained 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a noncoding region, which was consistent with previously studied Labeoninae mitogenomes. The phylogenetic analysis revealed that the subfamily Labeoninae was divided into four major clades. Notably, Discogobio was observed to be a non-monophyletic group and mixed with Discocheilus. The divergence time of Discogobio and Discocheilus can be placed during the time of the
