Phylogenetic tree of phycocyanin α- (A) and β-subunit (B), and 16S rRNA gene (C) of cyanobacterial species. For taxa, denoted with green-filled circles, phycocyanin structure are available in the PDB. The evolutionary history was inferred by using the Maximum Likelihood method and JTT matrix-based model23. The trees with the highest log likelihood are shown. The trees are drawn to scale with branch lengths measured in the number of substitutions per site. Evolutionary analyses were conducted in MEGA X22.
