Mitochondrial lineages of Pinus subsection Ponderosae to resolve the relationship of species named in the United States and Mexico.

Pinus subsection Ponderosae (Pinus, subgenus Pinus, section Trifoliae) includes about seventeen tree species distributed from Canada to Nicaragua. This research extended a previous study that used haplotypes based on a variable length intron in the mitochondrial gene nad1 to identify patterns within Pinus ponderosa. In the U.S.A., P. ponderosa is distributed over a vast geographic range and is thought to comprise at least two divergent lineages. We compared published mitochondrial haplotypes from across the range of P. ponderosa in the U.S.A. to haplotypes that we identified in related species of Pinus in Mexico and Central America. Alignments were performed on nucleotide sequences and relative relationships were determined among the newly identified haplotypes. These mitochondrial lineages, which move only through seed dispersal, provide information for detecting centers of diversification and glacial refugia for the Ponderosae that can be compared to phylogeographic patterns that are observed in pine’s pollen-dispersed plastid lineages.
