Drought Has a Greater Negative Effect on the Growth of the C₃ Chenopodium quinoa Crop Halophyte than Elevated CO₂ and/or High Temperature

Plants
Plant growth and productivity are predicted to be affected by rising CO2 concentrations, drought and temperature stress. The C3 crop model in a changing climate is Chenopodium quinoa Willd—a protein-rich pseudohalphyte (Amaranthaceae ...

Mitochondrial AOX Supports Redox Balance of Photosynthetic Electron Transport, Primary Metabolite Balance, and Growth in Arabidopsis thaliana under High Light

, 2019
When leaves receive excess light energy, excess reductants accumulate in chloroplasts. It is suggested that some of the reductants are oxidized by the mitochondrial respiratory chain.

Role of cyclic electron transport around photosystem I in regulating proton motive force

, 2015
In addition to ∆pH formed across the thylakoid membrane, membrane potential contributes to proton motive force (pmf) in chloroplasts. However, the regulation of photosynthetic electron transport is mediated solely by ∆pH.

Photochemical characteristics of Chlamydomonas mutant hpm91 lacking proton gradient regulation 5 (PGR5) during sustained H-2 photoproduction under sulfur deprivation

, 2019
Renewable H-2 photoproduction by Chlamydomonas reinhardtii offers a desirable bio-system for solar fuels. However, its large-scale application is hindered mainly due to lack of ideal strains.

PGR5 is needed for redox-dependent regulation of ATP synthase both in chloroplasts and in cyanobacteria

ABSTRACT The regulation of proton motive force ( pmf ) via ATP synthase activity is a critical mechanism by which photosynthetic organisms maintain redox homeostasis and activate photoprotective responses under fluctuating light conditions. Here, we used time-resolved electrochromic

Photosynthesis in fluctuating light

, 2023
Light is the essential energy source for plants to drive photosynthesis. In nature, light availability is highly variable and often fluctuates on very short time scales.

The role of the protein PGR5 in photoprotection and photosynthetic productivity in rice (Oryza sativa L.) [PDF]

, 2013
In plants, the need to efficiently respond to constant environmental fluctuations has led to the evolution of photoprotective mechanisms to regulate photosynthetic light reactions. One of such mechanism is cyclic electron transport (CET) which generates a pH gradient inducing the nonphotochemical quenching (NPQ) of excess excitation energy, synthesis ...

Identification of a Novel Mutation Exacerbated the PSI Photoinhibition in pgr5/pgrl1 Mutants; Caution for Overestimation of the Phenotypes in Arabidopsis pgr5-1 Mutant

Identification of a Novel Mutation Exacerbated the PSI Photoinhibition in pgr5/pgrl1 Mutants; Caution for Overestimation of the Phenotypes in Arabidopsis pgr5-1 Mutant
PSI photoinhibition is usually avoided through P700 oxidation. Without this protective mechanism, excess light represents a potentially lethal threat to plants. PGR5 is suggested to be a major component of cyclic electron transport around PSI and is important for P700 oxidation in angiosperms.
