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.
