Tomato and mini-cucumber tolerance to photoperiodic injury involves photorespiration and the engagement of nighttime cyclic electron flow from dynamic LEDs [PDF]

Frontiers in Plant Science
Controlled environment agriculture (CEA) is critical for achieving year-round food security in many regions of the world. CEA is a resource-intensive endeavor, with lighting consuming a large fraction of the energy.

Electron flow through NDH-1 complexes is the major driver of cyclic electron flow-dependent proton pumping in cyanobacteria [PDF]

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2020
Cyclic electron flow (CEF) around Photosystem I is vital to balancing the photosynthetic energy budget of cyanobacteria and other photosynthetic organisms. The coupling of CEF to proton pumping has long been hypothesized to occur, providing proton motive

Redox Modulation of Cyclic Electron Flow around Photosystem I in C3 Plants

Biochemistry, 2006
We have investigated the occurrence of cyclic electron flow in intact spinach leaves. In particular, we have tested the hypothesis that cyclic flow requires the presence of supercomplexes in the thylakoid membrane or other strong associations between proteins.

Defects in the Expression of Chloroplast Proteins Leads to H₂O₂ Accumulation and Activation of Cyclic Electron Flow around Photosystem I. [PDF]

Front Plant Sci, 2016
We describe a new member of the class of mutants in Arabidopsis exhibiting high rates of cyclic electron flow around photosystem I (CEF), a light-driven process that produces ATP but not NADPH. High cyclic electron flow 2 (hcef2) shows strongly increased

Nitric Oxide Alleviates Low-Light-Induced Photosynthetic Impairment by Improving Photosystem Coordination and Electron Transport in Tomato Seedlings [PDF]

Plants
Low light is a major environmental constraint that limits crop productivity by restricting photosynthetic carbon assimilation and disrupting photosynthetic function. Nitric oxide (NO) is an important signaling molecule involved in plant stress responses;

Limiting steps and the contribution of alternative electron flow pathways in the recovery of the photosynthetic functions after freezing-induced desiccation of Haberlea rhodopensis

Photosynthetica, 2022
Haberlea rhodopensis Friv. is unique with its ability to survive desiccation to an air-dry state during periods of extreme drought and freezing temperatures.

The Effects of Cold Stress on Photosynthesis in Hibiscus Plants. [PDF]

PLoS ONE, 2015
The present work studies the effects of cold on photosynthesis, as well as the involvement in the chilling stress of chlororespiratory enzymes and ferredoxin-mediated cyclic electron flow, in illuminated plants of Hibiscus rosa-sinensis.

Photoprotective roles of ascorbate and cstyleZostera marinacstyle

Photosynthetica, 2021
The oxygen-evolving complex (OEC) of Zostera marina is prone to deactivation under visible light, which results in a formation of the long-lived radical P680+. The mechanism to prevent damage caused by P680+ remains unclear.
