Other claims from this paper (4)
- Observation In most natural light conditions LHCII serves as an antenna of both Photosystem I and Photosystem II.
- Mechanism LHCII acting as antenna of both photosystems is required to achieve excitation balance between Photosystem I and Photosystem II.
- Association The amount of LHCII bound to both photosystems decreases as growth light intensity increases, and vice versa.
- Mechanism Regulating the expression of LHCII genes allows acclimation to different light intensities.
