- Intervention effect Aluminium above 3 mM strongly inhibited oxygen evolution in spinach PSII.
- Intervention effect Aluminium affected advancement of manganese cluster S states.
- Mechanism Aluminium released extrinsic polypeptides and disorganized the oxygen evolving manganese cluster.
- Intervention effect Maximum PSII quantum yield declined significantly after aluminium exposure.
- Intervention effect Aluminium damped chlorophyll fluorescence induction.
- Mechanism Energy transfer from antenna to reaction centres was impaired following LHCII alteration.
- Intervention effect F0 increased under aluminium exposure.
- Mechanism Aluminium interaction altered PSII protein secondary structure.
- Intervention effect Alpha helix content declined in aluminium PSII complexes.
- Intervention effect Beta sheet and random coil structures increased in aluminium PSII complexes.
- Intervention effect Aluminium inhibited the PSII electron transport chain.
