Abstract:
The mitochondrial genome (mitogenome) can provide important information for understanding phylogenetic analysis and molecular evolution. Herein, we amplified the complete mitogenome sequence of Pelteobagrus fulvidraco. The mitogenome was 16,526 bp in length and included 13 protein-coding genes (PCGs), 22 transfer RNA genes, two ribosomal RNA genes and a non-coding control region (D-loop). Both the organization and location of genes in the mitogenome were consistent with those from Siluriformes fishes previously published in GenBank. The phylogenetic relationships based on Bayesian inference (BI) and Maximum likelihood (ML) methods showed that P. fulvidraco has close relationships with Pelteobagrus eupogon and Tachysurus intermedius, suggesting that P. fulvidraco belongs to Tachysurus. This study provides evidence that Tachysurus, Pseudobagrus and Leiocassis do not form monophyly, but that these three genera form a monophyletic group. Our results provide reference for further phylogenetic research of the Bagridae species.
