Noncoding chloroplast DNA variation in Mexican pines

Abstract

Universal primers were used for PCR amplification of three noncoding regions of chloroplast DNA in order to study restriction site variation in 12 Mexican pine species. Two length mutations were identified that are of diagnostic value for two subgenera or sections of the genus. Phylogenetic analysis of the restriction site and length variation showed patterns of variation largely consistent with previous arrangements of these pines, except for the position of Pinus nelsonii, indicating that Pinus section Parraya Mayr, as circumscribed by Little and Critchfield (1969) and later authors, is not a monophyletic group.
