SlPGR5/SlPGRL1 pathway-dependent cyclic electron transport regulates photoprotection and chloroplast quality in tomato plants

Horticultural Plant Journal
The essential photoprotective role of proton gradient regulation 5 (PGR5)-dependent cyclic electron flow (CEF) has been reported in Arabidopsis, rice, and algae. However, its functional assessment has not been performed in tomato yet.

Flavodiiron Protein Activity Outcompetes Cyclic Electron Transport When Expressed in Angiosperm Nicotiana tabacum

Physiologia Plantarum, Volume 177, Issue 4, July/August 2025.
ABSTRACT In conditions of excess illumination, alternative electron transport pathways in the thylakoid membranes protect the photosynthetic apparatus against damage from eventual over‐reduction. Two main pathways downstream of photosystem I (PSI) enable alternative electron flow, mitigating PSI acceptor‐side limitation, while contributing to ATP ...

Flavodiiron proteins in Physcomitrium patens: navigating the edge between photoprotection and efficiency

The Plant Journal, Volume 121, Issue 4, February 2025.
Significance Statement Flavodiiron proteins are active in the photoprotection of photosynthetic organisms exposed to light fluctuations. This study identifies some potential drawbacks of FLV overexpression, opening hypotheses for their evolutionary loss in angiosperms.

Unique structural attributes of the PSI‐NDH supercomplex in Physcomitrium patens

The Plant Journal, Volume 120, Issue 5, Page 2226-2237, December 2024.
SUMMARY Cyclic electron transport around photosystem I (PSI) is essential for the protection of the photosynthetic apparatus in plants under diverse light conditions. This process is primarily mediated by Proton Gradient Regulation 5 protein/Proton Gradient Regulation 5‐like photosynthetic phenotype 1 protein (PGR5/PGRL1) and NADH dehydrogenase‐like ...

Role of cyclic and pseudo-cyclic electron transport in response to dynamic light changes in Physcomitrella patens

, 2019
Photosynthetic organisms support cell metabolism by harvesting sunlight and driving the electron transport chain at the level of thylakoid membranes.

Transcriptome dynamics in developing leaves from C3 and C4 Flaveria species

The Plant Journal, Volume 120, Issue 4, Page 1438-1456, November 2024.
SUMMARY C4 species have evolved more than 60 times independently from C3 ancestors. This multiple and parallel evolution of the complex C4 trait suggests common underlying evolutionary mechanisms, which could be identified by comparative analysis of closely related C3 and C4 species.

Chloroplast NADH dehydrogenase‐like complex‐mediated cyclic electron flow is the main electron transport route in C4 bundle sheath cells

New Phytologist, Volume 243, Issue 6, Page 2187-2200, September 2024.
Summary The superior productivity of C4 plants is achieved via a metabolic C4 cycle which acts as a CO2 pump across mesophyll and bundle sheath (BS) cells and requires an additional input of energy in the form of ATP. The importance of chloroplast NADH dehydrogenase‐like complex (NDH) operating cyclic electron flow (CEF) around Photosystem I (PSI) for ...

Strong heterologous electron sink outcompetes alternative electron transport pathways in photosynthesis

The Plant Journal, Volume 119, Issue 5, Page 2500-2513, September 2024.
SUMMARY Improvement of photosynthesis requires a thorough understanding of electron partitioning under both natural and strong electron sink conditions. We applied a wide array of state‐of‐the‐art biophysical and biochemical techniques to thoroughly investigate the fate of photosynthetic electrons in the engineered cyanobacterium Synechocystis sp.

The operation of PEPCK increases light harvesting plasticity in C4 NAD–ME and NADP–ME photosynthetic subtypes: A theoretical study

Plant, Cell &Environment, Volume 47, Issue 6, Page 2288-2309, June 2024.
Abstract The repeated emergence of NADP–malic enzyme (ME), NAD–ME and phosphoenolpyruvate carboxykinase (PEPCK) subtypes of C4 photosynthesis are iconic examples of convergent evolution, which suggests that these biochemistries do not randomly assemble, but are instead specific adaptations resulting from unknown evolutionary drivers.
