Effect of dark adaptation interval on the fast chlorophyll a fluorescence OJIP transients. OJIP transients were recorded on leaves of wild-type (A) and mutant plants (B), following the indicated dark adaptation intervals. Insets show the curve difference (ΔF_JP) of double normalized data at J (2 ms) and P, between 15 min dark adapted wildtype and 1, 2, and 5 min dark adapted wildtype (A) or clce-2 (B). (C) OJIP transients were recorded on wild-type leaves pre-incubated with 150 mM KCl in the light followed by the indicated dark adaptation intervals. Inset shows the curve difference (ΔF_JP) of double normalized data at J and P between 15-min dark-adapted KCl-treated wildtype and 1, 2, 3, and 5-min dark-adapted KCl-treated wildtype. The plotted transients are means ± SEM (n = 5 plants).
