Figure 5.
Increase in the efficiency of damage per flash as a function of the charge recombination extent. Calculated loss of PSII activity/flash (open symbols) and degradation of D1 protein (solid symbols) as a function of the extent of charge recombination during the dark interval expressed as t½ units (Fig. 2) using the data of Fig. 4. Thylakoids were exposed to light flashes in the absence (A) or presence (B) of DCMU, respectively.
