Complete mitochondrial genome of Hoek, 1883 (Balanomorpha: Balanidae) and a novel molecular phylogeny within Cirripedia.

Barnacles are crustaceans that are critical model organisms in intertidal ecology and biofouling research. In this study, we present the first mitochondrial genome of which is a circular molecule of 15,067 bp in length. Consistent with most barnacles, the mitochondrial genome of encodes 37 genes, including 13 PCGs, 22 tRNAs and 2 rRNAs. A novel insight into the phylogenetic analysis based on the nucleotide data of 13 PCGs showed that the clusters with (bootstrap value = 100) of the same genus, then groups with other Balanoidea species, the Chelonibiidae, Austrobalanidae and Tetraclitidae cluster together forming superfamily Coronuloidea. The result can help us to understand the novel classification within Balanomorpha.
