Abstract

Phylogenetic relationships among 30 species of the genus Pinus were studied using restriction site polymorphism in the large subunit of nuclear rDNA. Of the 58 restriction sites scored, 48 were phylogenetically informative, and the 30 species reduced to ten taxa when species with identical restriction site patterns were combined. These ten taxa corresponded to the currently recognized subsections of the genus, with the sole exception of P. Ieiophylla, which was identical in its pattern of restriction sites to all three species included from subsect. Oocarpae despite its being in a different section of sub. Pinus (Pinea instead of Pinus). A measure of the proportion of phylogenetic information contained within the data set (Homoplasy Excess Ratio, or HER) revealed that the character states were significantly nonrandomly distributed among the ten taxa (HER = 0.71, p < 0.01). Branchandbound searches using either Wagner or Dollo parsimony as the optimization criterion were carried out using PAUP in order to estimate phylogenetic relationships among the ten taxa. Three taxa (Picea pungens, Tsuga canadensis, and Larix decidua) were used independently as outgroups for purposes of rooting the trees. Despite the extreme differences in the assumptions underlying the Wagner and Dollo parsimony, the two gave surprisingly similar estimates of phylogeny, with both analyses supporting the monophyly of the two major subgenera Pinus and Strobus and differing in topology only in the placement of subsect. Ponderosae within subgenus Pinus. The likelihood for the Wagner tree was only slightly higher than that computed for the Dollo tree.
