Characterization of the complete mitochondrial genome of Pacific abalone Haliotis discus hannai.

The complete mitochondrial genome of Pacific abalone Haliotis discus hannai, an economically valuable shellfish in China, was sequenced and analyzed. The mitogenome was 16,716 bp in length and contained 13 protein-coding genes (PCGs), 22 tRNA genes, 2 rRNA genes, and a putative control region. The gene arrangement and orientation were identical with other Haliotis species. Phylogenetic tree was constructed based on 13 PCGs of 7 Haliotidae species to assess their phylogenetic relationship, the tree revealed that H. discus hannai was more closely to H. rufescens and H. iris.
