THE WATER-WATER CYCLE IN CHLOROPLASTS: Scavenging of Active Oxygens and Dissipation of Excess Photons
TL;DR: Whenever the water-water cycle operates properly for scavenging of active oxygens in chloroplasts, it also effectively dissipates excess excitation energy under environmental stress.

PGR5 Is Involved in Cyclic Electron Flow around Photosystem I and Is Essential for Photoprotection in Arabidopsis
TL;DR: It is proposed that the PGR5 pathway contributes to the generation of a Delta(pH) that induces thermal dissipation when Calvin cycle activity is reduced, thus preventing photosystem I photoinhibition.

The role of trace metals in photosynthetic electron transport in O2-evolving organisms
TL;DR: The roles of the transition metals in redox catalysts can in broad terms be related to their redox chemistry and to their availability to organisms at the time when the pathways evolved.

TL;DR: It is proposed that the PGRL1-PGR5 complex facilitates CEF in eukaryotes, a transmembrane protein present in thylakoids of Arabidopsis thaliana that shows perturbation of CEF, similar to PGR5-deficient plants.

An improved method, using saturating light pulses, for the determination of photosystem I quantum yield via P700 + -absorbance changes at 830 nm
TL;DR: In this paper, an improved method is introduced for the determination of the quantum yield of photosystem I. The new method employs saturating light pulses with steep rise characteristics to distinguish, in a given physiological state, centers with an open acceptor side from centers with a reduced acceptor.
