| fussnote | Nigericin stimulates PS II turnover in thylakoids at low but not at high light intensity in a low-frequency regime (6 Hz) at pH 8. When the external pH is decreased, stimulation by the uncoupler is also observed at high light intensity. Neither phosphorylation of LHCII nor unstacking of the thylakoids changes the effect of nigericin at pH 8. The observations are interpreted to indicate that ΔpH regulates PS II activity at two levels: (a) the transfer of excitation energy to the reaction centre: (b) PS II turnover. |
