Phylogenetic relationships of Santalales and Balanophora spp. inferred from Bayesian analysis (BI) of 18S rDNA, matR, RPB2, PI and AP3 gene sequences. Numbers above the branches are Bayesian posterior probabilities, and values below are maximum likelihood branch support determined by GARLI. Mitochondrial matR trees are based on a 1968 nucleotide alignment, and nuclear gene trees are based on 1739 (18S rDNA), 765 (PI), 864 (AP3), 549 (LFY), 1719 (RPB2) nucleotide alignments, respectively. See Supplementary Data Fig. S1 for RPB2 gene tree showing the obtained RPB2 sequences belonging to the d clade.
