Abstract
In the present study, the complete mitochondrial genome of the masked spinefoot Siganus puellus (Perciformes, Siganidae) is determined. The entire sequence is 16,504 bp in length, including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 1 control region. Gene organization and gene order are similar to those found in other rabbitfishes. Apart from ND6 and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. Overall base compositions of mitogenome are 28.6% of A, 29.5% of C, 25.6% of T and 16.3% of G. The overall mean genetic distances of 13 protein-coding genes among three Siganus species with known complete mitogenome ranges from 0.076 (COXII) to 0.154 (ATP6), higher than the divergence (0.107) of control region, which implies that ATP6 gene may be more appropriate for population genetic structure analyses of Siganus species.
