RAF1 and Rubisco L-subunits phylogenies of plants, green algae, and β-cyanobacteria. (A) Condensed RAF1 and L-subunit (RBCL) maximum-likelihood trees assembled using RAxML v.8. Full maximum-likelihood trees are shown in Fig. S1 and sequence accessions listed in Table S2. (B) Correlations of pairwise nonsynonymous d_N (leading to amino acid substitutions) and synonymous d_S (selectively neutral) distances for RAF1, L-subunit, and maturase K (matK, an unassociated chloroplast made protein; negative control) across green plants and algae (all significant at P < 0.0001).
