Abstract

The complete mitogenome sequence of Dentex hypselosomus was amplified by designing 15 primer pairs. The circle genome was 16,618 bp in size and the overall base composition was 27.04% of A, 26.38% of T, 17.08% of G, and 29.50 of C, with significant anti-G bias. The complete mitogenome of D. hypselosomus encodes 37 canonical mitochondrial genes, two non-coding regions, an L-strand replication region (OL), and a control region (D-loop). The D-loop contained termination sequence domain (TAS), central conserved domains (CSB-F, CSB-E, CSB-D, CSB-C, and CSB-A), and conserved sequence blocks (CSB-1, CSB-2, and CSB-3). Phylogenetic analysis of nine sparid species well supported the phylogenetic position of D. hypselosomus and revealed the phylogenetic relationship of the family Sparidae at the level of mitochondrial genomes.
