FIGURE 2. A. Bayesian tree of tribe Petunieae based on concatenated plastid intergenic spacers (trnS-trnG and trnL-trnF) and internal transcribed spacers of nuclear ribosomal DNA (ITS). Posterior probabilities values are shown above branches. Petunia highland clade: P. mantiqueirensis, P. bonjardinensis, P. reitzii, P. scheideana, P. saxicola, P. guarapuavensis, P. altiplana, and P. interior. Petunia lowland clade: P. integrigolia subsp. integrifolia, P. integrifolia subsp. depauperata, P. riograndensis, P. littoralis, P. bajeensis, P. inflata, P. axillaris subsp. axillaris, P. axillaris subsp. parodii, P. axillaris subsp. subandina, P. secreta, and P. occidentalis. Circles on nodes represent the most likely ancestral areas obtained with S-DIVA analyses. B. Ancestral area reconstructions for selected nodes (in rows) based on Bayesian binary Markov chain Monte Carlo (BBM). Pie graphs show probabilities of alternative ancestral range, low probability ancestral areas were merged and indicated in black (* Others). Each column shows the results for the different root distribution assumption.
