Abstract
The complete mitochondrial genome of the Epinephelus awoara was presented in this study. The mitochondrial genome is 16 798-bp long and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region. The gene order and composition of Epinephelus awoara mitochondrial genome was similar to that of most other vertebrates. The nucleotide compositions of the light strand in descending order is 27.35% of A, 16.53% of C, 28.44% of T, and 27.69% of G. With the exception of the NADH dehydrogenase subunit 6 (ND6) and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. The phylogenetic analysis by maximum-likelihood (ML) method shows that the Epinephelus awoara was closer to Epinephelus fasciatomaculosus in the phylogenetic relationship.
