Other claims from this paper (10)
- Intervention effect Illumination caused photoinhibition at every studied light intensity.
- Association Loss of PSII electron transfer activity correlated with declining fluorescence ratio.
- Association The photoinhibition rate constant was directly proportional to photon flux density.
- Observation The fluorescence ratio did not decrease under low light without lincomycin.
- Observation The fluorescence ratio did not decrease in darkness with lincomycin.
- Observation Quantum yield of photoinhibition remained constant across photon flux densities.
- Mechanism The authors infer one dominant in vivo photoinhibition mechanism across light intensities.
- Mechanism The authors consider the in vivo mechanism probably distinct from the anaerobic acceptor-side mechanism.
- Association Loss of PSII activity correlated strongly with D1 protein loss under low light.
- Observation Inactive PSII centers with D1 awaiting degradation did not accumulate under low light.
