The complete mitogenome and phylogeny analysis of Pseudohemiculter hainanensis (Boulenger, 1900) (Cyprinidae: Cultrinae)

Abstract

The Pseudohemiculter hainanensis (Boulenger, 1900) is a small Cyprinidae fish that has a wide distribution in China. In this study, we characterized the complete mitochondrial genome of P. hainanensis by the Illumina NovaSeq sequencing platform in Guangxi, China. The assembled mitogenome is 16,647 base pairs (bp) and consists of 13 protein-coding genes (PCGs), 22 transfer RNAs, two ribosomal RNAs, and a control region (D-loop). Nucleotide composition of the complete mitogenome is 29.69% (A), 24.82% (T), 27.97% (C), and 17.52% (G), with an A + T bias of 54.51%. The maximum-likelihood tree based on 13 PCGs showed that Pseudohemiculter hainanensis formed an independent lineage and P. hainanensis was closer to T. houdemeri.
