PGRL1 overexpression in Phaeodactylum tricornutum inhibits growth and reduces apparent PSII activity [PDF]

The Plant Journal, 2020
SummaryProton gradient regulation 5‐like photosynthetic phenotype 1 (PGRL1)‐dependent cyclic electron transport around photosystem I (PSI) plays important roles in the response to different stresses, including high light. Although the function of PGRL1 in higher plants and green algae has been thoroughly investigated, little information is available on

A Complex Containing PGRL1 and PGR5 Is Involved in the Switch between Linear and Cyclic Electron Flow in Arabidopsis [PDF]

Cell, 2008
During photosynthesis, two photoreaction centers located in the thylakoid membranes of the chloroplast, photosystems I and II (PSI and PSII), use light energy to mobilize electrons to generate ATP and NADPH. Different modes of electron flow exist, of which the linear electron flow is driven by PSI and PSII, generating ATP and NADPH, whereas the cyclic ...

PGR5/PGRL1 and NDH Mediate Far-Red Light-Induced Photoprotection in Response to Chilling Stress in Tomato [PDF]

Frontiers in Plant Science, 2020
Plants experience low ambient temperature and low red to far-red ratios (L-R/FR) of light due to vegetative shading and longer twilight durations in cool seasons. Low temperature induce photoinhibition through inactivation of the photosynthetic apparatus,

Complexities and protein complexes in the antimycin A-sensitive pathway of cyclic electron flow in plants [PDF]

Frontiers in Plant Science, 2013
Antimycin A-sensitive cyclic electron flow (AA-sensitive CEF) was discovered by Arnon and co-workers more than 50 years ago and serves to recycle electrons from ferredoxin (Fd) to plastoquinone (PQ).

Moderate overexpression of PROTON GRADIENT REGULATION 5 improves photosynthetic performance and plant growth under fluctuating low light in Arabidopsis thaliana. [PDF]

Plant J
SUMMARY Cyclic electron transport around photosystem I (PSI) plays an important role in regulating photosynthesis by balancing ATP/NADPH production and maintaining PSI function under fluctuating light. Although PGR5‐dependent photosynthetic regulation has been extensively studied under high or fluctuating light, its physiological significance under ...

Additive Effects of Multiple Photoprotective Mechanisms Drive Efficient Photosynthesis Under Variable Light Conditions. [PDF]

Plant Cell Environ
ABSTRACT To cope with changing external conditions, plants undergo dynamic acclimation processes that adjust their photosynthetic machinery, optimising energy use while minimising damage to photosystems (PS). Key photoprotective mechanisms include non‐photochemical quenching (NPQ), which dissipates excess excitation energy, and alternative electron ...

The Complementary Roles of Chloroplast Cyclic Electron Transport and Mitochondrial Alternative Oxidase to Ensure Photosynthetic Performance

Frontiers in Plant Science, 2021
Chloroplasts use light energy and a linear electron transport (LET) pathway for the coupled generation of NADPH and ATP. It is widely accepted that the production ratio of ATP to NADPH is usually less than required to fulfill the energetic needs of the ...

NTRC Effects on Non-Photochemical Quenching Depends on PGR5

Antioxidants, 2021
Non-photochemical quenching (NPQ) protects plants from the detrimental effects of excess light. NPQ is rapidly induced by the trans-thylakoid proton gradient during photosynthesis, which in turn requires PGR5/PGRL1-dependent cyclic electron flow (CEF ...

Light Quality-Dependent Regulation of Non-Photochemical Quenching in Tomato Plants

Biology, 2021
Photosynthetic pigments of plants capture light as a source of energy for photosynthesis. However, the amount of energy absorbed often exceeds its utilization, thus causing damage to the photosynthetic apparatus.

Impact of Salinity, Elevated Temperature, and Their Interaction with the Photosynthetic Efficiency of Halophyte Crop Chenopodium quinoa Willd

Agriculture, 2023
Chenopodium quinoa is a genetically diverse crop that can adapt to a wide range of environments, including temperatures and salinities. However, only a few studies have assessed the combined effects of two or more environmental factors on C. quinoa. Here,
