Diadinoxanthin (DD) and diatoxanthin (Dt) content of isolated thylakoids before (control) and after illumination with 1.000 μmol m⁻² s⁻¹ for 25 min in the presence of 30 mM ascorbate and 2 mM FeCN (HL). The illumination was performed at room temperature with a Chl concentration of 10 μg mL⁻¹. DD and Dt concentrations are calculated as mM pigment M⁻¹ Chl a. Fig. 6 shows the mean values of three independent thylakoid preparations with the respective standard deviations
