Characterization and phylogenetic analysis of the complete mitochondrial genome of Prolixicheilus longisulcus (Teleost: Cyprinidae).

In this study, we assembled the complete mitochondrial genome of Prolixicheilus longisulcus based on high-throughput Illumina sequencing. The complete mitochondrial genome of P. longisulcus was 16,598 bp in size. It was made up of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 1 control region. The overall base composition included A(32.38%), T(26.08%), C(26.32%) and G(15.22%). The phylogenetic tree was conducted to provide a relationship within Labeoninae based on the maximum likelihood (ML) method. The ML tree demonstrated this species had the closest relationship with Cophecheilus bamen. These results should help to better understand the phylogenetic evolution of Labeoninae.
