Abstract

In this study, we first sequenced the mitochondrial genome (mitogenome) of Schizothorax argentatus. The circular mitogenome of S. argentatus is 16,587 bp long, containing 13 protein-coding genes, 22 tRNA genes, two ribosomal RNA genes, and a control region (D-loop region). The base composition is AT biased (63.11%). A phylogenetic tree confirms monophyly at the genus level within Cyprinidae and supports S. argentatus as sister to Schizothorax pseudoaksaiensis.

Keywords: Mitochondrial genome; Schizothorax argentatus; phylogenetic tree; phylogeny.
