Mitochondrial lineages of Pinus ponderosa s.l. in the USA and related species in Mexico and Central America.

Pinus subsection Ponderosae includes approximately 17 tree species distributed from southwestern Canada to Nicaragua. Our research builds on a previous study that used a variable-length intron in the nad1 mitochondrial gene to identify patterns among ponderosa pine populations. Ten haplotypes were detected for United States populations of Pinus ponderosa s.l. Here we evaluate whether some populations treated as P. ponderosa in the United States are actually more closely related to pine species in Mexico and Central America than they are to each other. We obtained and analyzed mitochondrial sequences for additional samples of interest from United States populations of P. ponderosa as well as P. arizonica, P. cooperi, P. devoniana, P. douglasiana, P. durangensis, P. engelmannii, P. hartwegii, P. maximinoi, P. montezumae, P. pseudostrobus, and P. yecorensis. The sequence alignments were analyzed to infer relationships among the mitochondrial haplotypes and determine which populations in the United States were most closely related to those in Mexico.
