Abstract
In the present study, the complete mitogenome sequence of Gnathopogon imberbis is determined using PCR amplification and DNA sequencing, which contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a non-coding control region with the total length of 16,598 bp. Except for eight tRNA and ND6 genes, all other mitochondrial genes are encoded on the H-strand. The codon usage followed the typical vertebrate mitochondrial pattern (ATG or GTG for start codon and TAA or TAG for stop codon). The overall nucleotide composition was 30.0% A, 27.0% T, 25.8% C and 17.2% G, with an A + T bias of 57.0%. The complete mitochondrial genome sequence will be useful for phylogenetic analysis and studies of population genetics of G. imberbis.
