The complete mitochondrial genome of Hexagrammos agrammus (Scorpaeniformes: Hexagrammidae) by next-generation sequencing

Abstract

The complete mitochondrial genome of the Hexagrammos agrammus is presented in this study. The mitochondrial genome is 16,512 bp long and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region. The gene order and composition were similar to those of most other vertebrates. The nucleotide compositions of the heavy strand are 17.27% of G, 26.10% of T, 26.85% of A, and 29.78% of C. With the exception of the NADH dehydrogenase subunit 6 (ND6) and 8 tRNA genes, all other mitochondrial genes are encoded on the heavy strand. The phylogenetic analysis by neighbour-joining (NJ) method showed that H. agrammus has the closer relationship with Hexagrammos otakii and Hexagrammos lagocephalus in the phylogenetic relationship.
