- Observation Photosynthetic parameters remained largely unchanged under growth or light-saturating conditions.
- Observation At light saturation, non-photochemical quenching increased reversibly in darkness.
- Observation At light saturation, antheraxanthin and zeaxanthin increased fivefold.
- Observation Functional PSII centers, DCMU-binding sites and D1 protein pool size showed no consistent concentration change.
- Observation D1 protein synthesis was rapid.
- Intervention effect Excess irradiance reduced O2 evolution quantum yield and PSII efficiency.
- Intervention effect Excess irradiance was associated with a 15- to 20-fold increase in antheraxanthin and zeaxanthin.
- Intervention effect Excess irradiance sustained an increase in nonphotochemical quenching.
- Intervention effect Functional PSII center concentration decreased under excess irradiance.
- Observation D1 protein concentration declined after functional PSII centers decreased.
- Observation DCMU-binding sites did not decrease alongside D1 protein.
- Intervention effect D1 protein synthesis rates remained unchanged at excess irradiance.
