Complete mitochondrial genome and phylogenetic relationship of ornate threadfin bream, Nemipterus hexodon (Perciformes, Nemipteridae)

Abstract

The complete mitochondrial genome of the ornate threadfin bream, Nemipterus hexodon, was first determined by the pairs-walking sequencing in this study. The circular mtDNA molecule was 17,115 bp in size and the overall nucleotide composition of H-stand was A (29.55%), T (27.36%), G (16.08%), and C (27.01%), with a slight bias towards A + T. The complete mitogenome encoded 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 2 non-coding regions (an origin of L-strand replication and a control region). The Bayesian tree supported the phylogenetic position of N. hexodon, which provided useful information for phylogenetic relationship in genus Nemipterus.
