Summarizing analysis of Chl- a fluorescence yields of dark-adapted wild-type and mutant plants. The analysis is based on similar time course experiments as shown in Figure 7. The individual bars indicate fluorescence emitted from LCHs associated with PSII (dark green bars; Fo, i.e. after application of AL at a PFD of 4000 μmol·m-2·s-1), whereas (light green bars) and (red bars) indicate the relative fluorescence yield emitted from free antennae, which either can (light green bars) or cannot (red bars) be partially quenched by FR illumination (QFR). The yellow bars represent the maximum Fv emitted from PSII reaction centers. The data were normalized for Fm (= 1) and represent the mean ± SE of n = 3 measurements
