The complete mitochondrial genome of Dermogenys pusilla (Beloniformes: Hemiramphidae) and phylogenetic studies of Beloniformes

Abstract

In this study, the complete mitochondrial genome of Dermogenys pusilla was firstly determined. The complete genome is 16,529 bp in length. It contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, a putative control region, and 1 origin of replication on the light-strand. The gene organization, nucleotide composition, and codon usage are similar to other Hemiramphidae. The overall nucleotide composition was 30.73% A, 28.18% T, 26.48% C, and 14.61% G, respectively. All protein-coding genes started with Met, ND1, ND2, CO1, ATP8, ATP6, CO3, ND3, ND4L, ND5 and ND6 ended by TAA as a stop codon, ND4 ended by AGA as a stop codon, CO2 and Cytb use an incomplete stop codon T. The lengths of 12S ribosomal RNA and 16S ribosomal RNA are 941 bp and 1670 bp, respectively. The length of control region is 862 bp, ranging from 15,668 bp to 16,529 bp. The complete mitochondrial genome sequence provided here would help us understand the evolution of ratite and conservation genetics of D. pusilla in the future.
