TL glow curves for the wild-type and ΔPsbP leaves. A, The TL band observed in the wild-type leaves. B, The ability of the TL band to decay in the dark in ΔPsbP leaves. The leaves were incubated in the dark at 20°C for the indicated period and then illuminated by a single flash at 0°C. B, The development of TL B-band capability during weak light illumination in dark-adapted ΔPsbP leaves. ΔPsbP leaves were dark adapted for 5 h and then incubated under dim light (0.5 μE m−2 s−1) at 20°C for the indicated period. The sample leaves were excited with a single flash at 0°C after 10 min of incubation in the dark. The TL B-band originates from recombination of the QB−/S2 charge pair in PSII.
