Biomass production and photon conversion efficiency of WT, npq4 and npq4 lhcsr1 mutants.
Panel (a) biomass produced as grams of dry weight per liter of WT (black) npq4 mutant (red) and npq4 lhsr1 (blue) mutant at the different light regimes (Light A–E). Panel (b): photon conversion efficiency (PCE) calculated as the ratio between the dry weight and the average photon flux density [(g L-1)/(µmol photons m-2?s-1)]. Statistical significant differences were obtained between WT, npq4 and npq4 lhcsr1 according to two-tailed non parametric Kruskal-Wallis test multiple comparison (n?=?5, a?=?0.05 for all condition, p values of 0.0064 and 0.0253 for Light A and B respectively). Wilcoxon-Mann-Whitney test was applied for two samples comparison obtaining statistically significant differences for npq4 compared to WT in all growth conditions (n?=?5, a?=?0.05, p?=?0.009; 0.0216; 0.009; 0.009; 0.009 for Light A–E respectively) but not for npq4 lhcsr1.
