Mitochondrial evolution across lineages of the vampire barnacle Notochthamalus scabrosus

Abstract

Eight whole mitochondrial genomes from the barnacle Notochthamalus scabrosus, with one from the northern lineage and seven from the divergent southern lineage, are presented. The annotated and aligned data were analyzed for signals of non-neutral evolution. Overall, these data are consistent with purifying selection operating on the protein-coding regions of the mitochondrion. However, a notable region of nonsynonymous substitution at the 3′ end of the ND2 gene region, along with unusual site frequency spectra in two other gene regions, was identified.
