Abstract
Schizothorax eurystomus, Kessler 1872 is a unique economic fish in Xinjiang, China that is rarely seen in the market. Next-generation sequencing (NGS) was used to determine the complete mitochondrial genome of S. eurystomus collected from the Yarkand River in Xinjiang. The results showed that the mitochondrial genome is a circular, 16,488-bp-long nucleotide with the typical vertebrate genome structure of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and a control region. The termination-associated sequence (TAS), central conserved sequence block (CSB), and conserved sequence block were detected in the control region. Phylogenetic analysis placed S. eurystomus in a fully supported clade with S. biddulphi, and that clade was sister to S. yunnanensis. To our knowledge, this is the first study on the complete mitochondrial genome of S. eurystomus from the Yarkand River in Xinjiang, and it provides baseline genetic information for future studies.
