Abstract
The complete mitochondrial genome of the Synanceia verrucosa has been sequenced. The mitochondrial genome is 16,506 bp in length, containing 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and one control region. The gene order and the composition of S. verrucosa mitochondrial genome were similar to that of most other vertebrates. The overall nucleotides base composition of the heavy strand is A (31.01%), G (15.06%), C (25.60%), and T (28.34%). 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 tRNA-Ser2 gene lacked DHC arm and could not fold into a typical clover-leaf secondary structure. Seen from the phylogenetic tree, a stonefish (S. verrucosa), two lionfishes, and eight rockfishes from the same order (Scorpaeniformes) clustered into one branch.
