Phylogenetic relationships of 35 pines and four outgroups as determined from different data partitions. A) Full alignment without ycf1 and ycf2. B) Exon nucleotide sequences. C) Exon nucleotide sequences without ycf1 and ycf2. Support values are only shown for nodes with bootstrap/posterior probability values less than 100%/1.0, and are shown as ML bootstrap/MP bootstrap/BI posterior probability. Dashes indicate < 50% bootstrap support or < .50 posterior probability. Accessions whose position differs from that in full alignment analysis indicated in bold.
