The complete mitochondrial genome of Hemiramphus far (Beloniformes; Hemiramphidae) and phylogenetic studies of Beloniformes

Abstract

The complete mitochondrial genome of this species was first determined in this study, which is 16,544 bp in length, the overall base composition includes C(27.0%), A(30.7%), T(27.1%) and G(15.2%). Moreover, the 13 protein-coding genes (PCGs) encode 3801 amino acids in total, 12 of which use the initiation codon ATG except COI uses GTG, most of them have TAA or TAG as the stop codon, whereas four protein-coding genes (COII, COIII, ND4 and Cytb) ended with the incomplete stop codon represented as a single T. The phylogenetic tree based on the neighbour-joining method was constructed to provide relationship within Beloniformes, the result supported that H. far was clustered with Hyporhamphus dussumieri.
