Artificially induced fluctuations in growth light reveal the photoprotective effect of psbS overexpression in rice. An example of NPQ, qP and relative ETR measured within artificially fluctuating light (a, c, e) and static light (b, d, f) for overexpressing (OE) and wild-type (WT) lines. Light fluctuated within the Fytoscope (PSI, Brno, Czech Republic) cabinet between 1500 and 100 µmol m−2 s−1 every 3 min or was kept static at 800 µmol photons m−2 s−1 during the light phase of a 12 h photoperiod. The total daily PPFD was the same for both treatments. To clearly demonstrate the differences between lines and treatments a 2 h portion during mid-day is shown over a 3-day period during the experiment. Three sensors were used each for WT and OE. The Monitoring Pam pulses (applied every 5 min) and the light fluctuations were not synchronised. Values are average ± standard errors of the means from two independent experiments. n = 18 (3 moniPAM heads per plant type)
