The complete mitochondrial genome of Diadema setosum (Aulodonta: diadematidae)

The complete mitochondrial genome of Diadema setosum was sequenced by using long-PCR and primer walking methods. The complete mitochondrial genome is a 15,708 bp circular molecule, which contains 22 tRNAs, 2 rRNAs, and 13 protein-coding genes as well as a non-coding control region as in other urchin. The genome was composed of 27.5% A, 30.7% T, 24.3% C, and 17.5% G. The control region is 133 bp. Twelve of the 13 mitochondrial protein-coding genes use ATG as their start codon while the ATP8 gene starts with GTG. Six of the 13 mitochondrial protein-coding genes use TAA as their complete stop codon while seven of them use TAG as their complete stop codon.
