Concerted evolution of duplicated control regions within an ostracod mitochondrial genome.
The luminescent marine ostracod Vargula hilgendorfii comprises distinct populations around the Japanese islands. Its mitochondrial DNA is unusual, with duplicated control regions (CRs; CR#1 and CR#2). We determined the sequences of ostracod CRs in 7 different populations. The sequences of CR#1 and CR#2 within any population were extremely similar, above 99.7%; moreover, their derived evolutionary tree indicates that the pairs of CRs have evolved in concert within each mitochondrial genome. These results suggest that an exact replication mechanism controls the concerted evolution of CRs.
