PGRL2 Triggers Degradation of PGR5 in the Absence of PGRL1 [PDF]
Nature Communications, 2021 It is currently thought that the thylakoid proteins PGRL1 and PGR5 form a complex to mediate cyclic electron flow (CEF) around photosystem I. Here the authors show that CEF can in fact be mediated by PGR5 alone and that PGRL1 and the homologous PGRL2 ...

The Physiological Functionality of PGR5/PGRL1-Dependent Cyclic Electron Transport in Sustaining Photosynthesis [PDF]
Frontiers in Plant Science, 2021 The cyclic electron transport (CET), after the linear electron transport (LET), is another important electron transport pathway during the light reactions of photosynthesis.

Autophagy Induced Accumulation of Lipids in pgrl1 and pgr5 of Chlamydomonas reinhardtii Under High Light [PDF]
Frontiers in Plant Science, 2022 Chlamydomonas (C.) reinhardtii is a potential microalga for lipid production. Autophagy-triggered lipid metabolism in microalgae has not being studied so far from a mutant of proton gradient regulation 1 like (PGRL1) and proton gradient regulation 5 ...

Inactivation of photosynthetic cyclic electron transports upregulates photorespiration for compensation of efficient photosynthesis in Arabidopsis [PDF]
Frontiers in Plant Science, 2023 Plants have multiple mechanisms to maintain efficient photosynthesis. Photosynthetic cyclic electron transports around photosystem I (CET), which includes the PGR5/PGRL1 and NDH pathways, and photorespiration play a crucial role in photosynthetic ...

Nature Communications, 2019 In Arabidopsis, PGR5 and PGRL1 heterodimers enable cyclic electron flow to safeguard photosystem I during high light intensity. Here, the authors provide evidence that cyanobacteria, while lacking an obvious PGRL1 homologue, use an analogous PGRL1-like ...
