- •
EBR enhances the photosystem II photochemistry and electron-transport rate in pea thylakoid membranes.
- •
EBR changes the kinetics of oxygen evolution and decreases the ratio of functionally active PSII伪 to PSII尾 centers.
- •
EBR induces alterations in the thermodynamic parameters of photosynthetic membranes.
- •
EBR causes reorganization of the main pigment–protein complexes and partial unstacking of thylakoid membranes.
