Abstract
Platypharodon extemus is a monotypic species of Schizothoracine fishes and it was listed as Endangered species in the “China Red Data Book (Pisces)”, Vulnerable (V) by the National Environmental Protection Agency and Endangered Species Scientific Commission. So far, little mitochondrial genome information of this genus has been described. In this study, we obtained the complete mitochondrial DNA genome sequences of this species. The mitogenome was 16,668 bp in length, which consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 2 noncoding regions. The base composition of this mitochondrial genome was 28.6% A, 27.3% T, 18.2% G, 25.9% C, with a high A + T content (55.9%). The complete mitochondrial genome of P. extremus would be of great utility in the phylogenetic analysis of the schizothoracine fishes and also provide meritorious insights into the deeper problems of the phylogenic analysis.
