Mitochondrial genome of Parasinilabeo longicorpus provides insights into the phylogeny of Labeoninae

Abstract

Parasinilabeo longicorpus is an endemic species living in the karst regions of South China. In the present study, we firstly performed the complete mitogenome sequence of P. longicorpus (Cyprinidae: Labeoninae). Results showed that the mitogenome was 16,596 bp in length and contained 37 genes (i.e. 13 protein-coding, 22 transfer RNA, and two ribosomal RNA genes) and a single control region. The genetic arrangement and distribution of the mitogenome were consistent with that of other vertebrates. Phylogenetic analysis of the protein-coding genes indicated that Labeoninae species could be divided into three branches. Parasinilabeo longicorpus showed close evolutionary relationship with P. assimilis. This study should help to improve our understanding of the mitogenomes and phylogenetics of Labeoninae, and provide a foundation for further taxonomic, systematic, and genetic studies.
