Evolutionary relationships of RPA1 proteins. (A) RPA1A group, (B) RPA1B group, (C) RPA1C group. The evolutionary history was inferred using the Maximum-Likelihood method performed with MEGA5.2 software package. Amino acid sequences were aligned using ClustalW and used to produce phylogenetic trees using the Jones-Taylor-Thornton (JTT) amino acid substitution model. Numbers next to the branches are bootstrap values (1000 replicates). Branches that show less than 70% bootstrap support were collapsed. Some RPA1 sequences denoted by asterisk (^*) [sorghum RPA1C-3, P. patens RPA1B, and V. cateri RPA1B] contain DBD-F deletion. Yeast RPA1 was used as an outgroup to root the tree. Except for bootstrapping and choice of model, all other parameters were left at default settings.
