<p>Shown are amino acid residue numbers in <i>C.reinhardtii</i> PDS, species in which the missense mutation was isolated, numbering of the original substitutions in homologous PDS proteins and phenotype of the substitutions. Synechococcus PCC7942 and Synechocystis PCC 6803 are listed. Colour coding of amino acids is the same as in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0099894#pone-0099894-g007" target="_blank">Figure 7</a>.</p
