The complete mitochondrial genome of Temnopleurus hardwickii (Camarodonta: Temnopleuridae)

Abstract

The complete mitochondrial genome of Temnopleurus hardwickii was sequenced using long-PCR and primer walking methods. The complete mitochondrial genome is a 15,696 bp circular molecule which contains 22 tRNAs, 2 rRNAs, 13 protein-coding genes as well as a non-coding control region as in other urchin. The genome was composed of 32.9% A, 29.3% T, 21.4% C and 16.4% G, showing a slight AT bias (62.3%). The control region is 156 bp. Twelve of the 13 mitochondrial protein-coding genes use ATG as their start codon while the ATP8 gene starts with GTG. All the 13 mitochondrial protein-coding genes use TAG or TAA as their complete stop codon.
