Examples of selected mutant strains with altered fluorescence parameters. Cells were diluted to the same cell density (OD750 = 0.2) prior to measurements, and examples of EMS-induced mutant strains exhibiting significant variation from WT are shown in each panel. a F 0/Area; b PSII quantum yield in dark-adapted colonies; c PSII quantum yield in colonies illuminated with 450 µmol photons m−2 s−1; d NPQ induction and recovery (light was switched off after 300 s). WT n = 9
