Characterization of the complete mitochondrial genome of Pseudocrossocheilus liuchengensis (Cypriniformes: Cyprinidae)

Abstract

Pseudocrossocheilus liuchengensis is a Labeoninae fish species endemic to China. In this study, the complete mitochondrial genome of P. liuchengensis was firstly determined and described. It was 16,600 bp in length and composed by 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a control region. The overall nucleotide composition was 32.0% of A, 15.5% of G, 25.8% of T, and 26.7% of C, with the AT-rich feature (57.8%). Phylogenetic analysis validated the taxonomic status of P. liuchengensis, exhibiting the closest relationship with P. bamaensis.
