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

open access: yes
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

Transcriptome analysis reveals the mechanism of mixed oligosaccharides in the response of rice seedlings to abiotic stresses

open access: yesFrontiers in Plant Science
Salinity and alkalinity stresses severely suppress rice seedling growth and substantially reduce rice yield; whereas the application of oligosaccharides as plant growth regulators has been demonstrated to remarkably enhance crop tolerance to abiotic ...

PROTON GRADIENT REGULATION5 Is Essential for Proper Acclimation of Arabidopsis Photosystem I to Naturally and Artificially Fluctuating Light Conditions

open access: yes, 2012
In nature, plants are challenged by constantly changing light conditions. To reveal the molecular mechanisms behind acclimation to sometimes drastic and frequent changes in light intensity, we grew Arabidopsis thaliana under fluctuating light conditions,

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

open access: yes, 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 ...

Brassinosteroids Act as a Positive Regulator of Photoprotection in Response to Chilling Stress

open access: yes, 2019
Photoprotection is an important strategy adopted by plants to avoid photoinhibition under stress conditions. However, the way in which photoprotection is regulated is not fully understood.

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

open access: yesIdentification 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.
