The complete mitochondrial genome of the spotted steed, Hemibarbus maculatus (Teleostei, Cypriniformes)

Abstract

The complete mitogenome sequence of the spotted steed (Hemibarbus maculatus) was determined using long PCR reactions. The genome is 16,611 bp long and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region. The gene order and composition of H. maculatus was similar to that of most other vertebrates. The base composition of H-strand in descending order is A (29.16%), C (27.41%), T (25.93%), and G (17.50%), with an AT content of 55.09%. The Kimura two-parameter distances between mitogenome sequences of H. maculatus and Hemibarbus labeo, Hemibarbus barbus, Hemibarbus longirostris, Hemibarbus mylodon were 2.09%, 2.35%, 12.77%, and 13.92%, respectively. The phylogenetic relationships among the five Hemibarbus species based on the whole mitogenome sequence data were (((H. barbus, H. labeo), H. maculatus), (H. longirostris, H. mylodon)).
