Figure 3

Phylogenetic relationship of PUB-ARM proteins of Arabidopsis, rice, poplar and moss. (A) Simplified Bayesian phylogenetic tree depicting the relationship among class I–IV PUB-ARM proteins, as defined by Zeng et al. (2008). The bar represents 0.5 PAM distance. The tree derived from the analysis of the 2683 amino acid alignment; the full tree in Supporting Figure S2. (B) Subtree of (A) depicting the relationship among class IV proteins, which include SAUL1-type proteins. Arabidopsis SAUL1 (AtPUB44) is highlighted in gray; the numbers at the nodes are Bayesian posterior probabilities.
