The complete mitochondrial genome of Grammistes sexlineatus (Perciformes, Serranidae)

Abstract The complete mitochondrial genome of Grammistes sexlineatus was first determined and studied in the present study. The mitochondrial genome was 16,502 nucleotides that contained 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes and one putative control region. The overall base composition of G. sexlineatus was T 23.74%, C 31.05%, A 28.79%, and G 16.42%, with a slight A + T bias of 52.53%. The gene order and composition of G. sexlineatus mitogenome was similar to the most vertebrate. Meanwhile, a termination-associated sequence (TAS) and the conserved sequence blocks (CSB-2 and CSB-3) were determined in G. sexlineatus control region. The mitochondrial genome would play key role in phylogenetics analysis of the Serranidae.
