Tandemly repeated sequences in the mitochondrial DNA control region and phylogeography of the Pike-Perches Stizostedion.
Mol Phylogenet Evol. 1998 Dec; 10(3):310-22.MP

Abstract

DNA sequences from the mitochondrial DNA control region are used to test the phylogeographic relationships among the pike-perches, Stizostedion (Teleostei: Percidae) and to examine patterns of variation. Sequences reveal two types of variability: single nucleotide polymorphisms and 6 to 14 copies of 10- to 11-base-pair tandemly repeated sequences. Numbers of copies of the tandem repeats are found to evolve too rapidly to detect phylogenetic signal at any taxonomic level, even among populations. Sequence similarities of the tandem repeats among Stizostedion and other percids suggest concerted evolutionary processes. Predicted folding of the tandem repeats and their proximity to termination-associated sequences indicate that secondary structure mediates slipped-strand mispairing among the d-loop, heavy, and light strands. Neighbor-joining and maximum parsimony analyses of sequences indicate that the genus is divided into clades on the continents of North America and Eurasia. Calibrating genetic distances with divergence times supports the hypothesis that Stizostedion dispersed from Eurasia to North America across a North Pacific Beringial land bridge approximately 4 million years before present, near the beginning of the Pliocene Epoch. The North American S. vitreum and S. canadense appear separated by about 2.75 million years, and the Eurasian S. lucioperca and S. volgensis are diverged by about 1.8 million years, suggesting that speciation occurred during the late Pliocene Epoch.
