The Role of Alternative Electron Pathways for Effectiveness of Photosynthetic Performance of Arabidopsis thaliana, Wt and Lut2, under Low Temperature and High Light Intensity

Plants, 2022
A recent investigation has suggested that the enhanced capacity for PSI-dependent cyclic electron flow (CEF) and PSI-dependent energy quenching that is related to chloroplast structural changes may explain the lower susceptibility of lut2 to combined ...

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,

Effects of the Herbicide Imazethapyr on Photosynthesis in PGR5- and NDH-Deficient Arabidopsis thaliana at the Biochemical, Transcriptomic, and Proteomic Levels

Journal of Agricultural and Food Chemistry, 2016
Photosynthesis is a very important metabolic pathway for plant growth and crop yield. This report investigated the effect of the herbicide imazethapyr on photosynthesis in the Arabidopsis thaliana pnsB3 mutant (a defect in the NDH pathway) and pgr5 ...

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 ...

Two proteins co-expressed with photosynthetic regulators affect photosynthetic dynamics linked to changes in thylakoid pigment content and composition. [PDF]

Plant Biol (Stuttg)
Two factors identified by co‐expression analysis of photosynthetic regulators are described, which are involved in thylakoid pigment content and composition and, through their function, shape the dynamics of NPQ. Abstract Rapid fluctuations in light intensity require swift regulatory adjustments of photosynthesis. Although the major plant regulators of

Photoautotrophic and sustained H2 production by the pgr5 mutant of Chlamydomonas reinhardtii in simulated daily light conditions

International Journal of Hydrogen Energy
Green algae, such as Chlamydomonas reinhardtii, can produce H2 efficiently using their hydrogenases, but these enzymes are O2-sensitive and compete with CO2-fixation for electrons.

Cyclic Electron Transport via the NDH Complex Sustains Photosynthesis and Productivity Under Fluctuating and Sub-Optimal Environments. [PDF]

Physiol Plant
ABSTRACT The chloroplast NADH dehydrogenase‐like (NDH) complex mediates cyclic electron transport (CET) around photosystem I (PSI) and contributes to photosynthetic regulation and photoprotection under various environmental stresses. Although NDH function has been extensively characterized under controlled conditions, NDH‐deficient mutants often show ...

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).

A pgr5 suppressor screen uncovers two distinct suppression mechanisms and links cytochrome b6f complex stability to PGR5. [PDF]

Plant Cell
Abstract PROTON GRADIENT REGULATION5 (PGR5) is thought to promote cyclic electron flow, and its deficiency impairs photosynthetic control and increases photosensitivity of photosystem (PS) I, leading to seedling lethality under fluctuating light (FL).

High light-induced changes in whole-cell proteomic profile and its correlation with the organization of thylakoid super-complex in cyclic electron transport mutants of Chlamydomonas reinhardtii

Frontiers in Plant Science, 2023
Light and nutrients are essential components of photosynthesis. Activating the signaling cascades is critical in starting adaptive processes in response to high light.
