Safety valves for photosynthesis

Safety valves for photosynthesis

Recent studies have provided new insights into the ways that plants may dissipate excess photons and electrons, thereby protecting the photosynthetic apparatus against light-induced damage. These ‘safety valves’ include nonphotochemical mechanisms for quenching excited chlorophylls, as well as alter...

Zusammenfassung:Recent studies have provided new insights into the ways that plants may dissipate excess photons and electrons, thereby protecting the photosynthetic apparatus against light-induced damage. These ‘safety valves’ include nonphotochemical mechanisms for quenching excited chlorophylls, as well as alternative electron acceptors such as oxygen.
