Bayesian inference of the PPO gene family phylogeny. Branch width and numbers at nodes correspond to posterior probabilities. The tree is outgroup rooted with laccases (shown in grey). The P. patens PPOs are shown in red. Coding sequences were obtained from cosmoss.org version V1.6 (see Supplementary Table S1).
