A tomato chloroplast-targeted DnaJ protein, SlDnaJ20 maintains the stability of photosystem I/II under chilling stress

Plant Signaling & Behavior, 2022
DnaJ proteins are key molecular chaperones that act as a part of the stress response to stabilize plant proteins, thereby maintaining protein homeostasis under stressful conditions.

SiO2 nanopriming protects PS I and PSII complexes in wheat under drought stress

Plant Nano Biology, 2022
: Drought is an important abiotic stress that hampers the growth of plants by inhibiting photosynthesis resulting in major crop losses. Silicon is known for its role to alleviate impact of various abiotic stresses in plants. In the present study, drought

Electron flow from PSII to PSI under high light is controlled by PGR5 but not by PSBS

Frontiers in Plant Science, 2015
Absence of the PROTON GRADIENT REGULATION 5 (PGR5) protein from plant chloroplasts prevents the induction of strong trans-thylakoid proton gradient (ΔpH) and consequently also the thermal dissipation of excess energy (NPQ).

Responses of photosystem to long-term light stress in a typically shade-tolerant species Panax notoginseng

Frontiers in Plant Science, 2023
Photosynthetic adaptive strategies vary with the growth irradiance. The potential photosynthetic adaptive strategies of shade-tolerant species Panax notoginseng (Burkill) F. H. Chen to long-term high light and low light remains unclear.

Partially dissecting the steady-state electron fluxes in Photosystem I in wild-type and pgr5 and ndh mutants of Arabidopsis

Frontiers in Plant Science, 2015
Cyclic electron flux (CEF) around Photosystem I (PS I) is difficult to quantify. We obtained the linear electron flux (LEFO2) through both photosystems and the total electron flux through PS I (ETR1) in Arabidopsis in CO2-enriched air. DeltaFlux = ETR1

Overexpression of Rubisco Activase Improves Photosynthesis and Plant Growth in Rice Under Fluctuating Light Under Future High CO2 Conditions

Plant, Cell &Environment, EarlyView.
ABSTRACT Rubisco activase mediates the activation of Rubisco, the key photosynthetic CO2‐fixing enzyme, and plays a crucial role in regulating photosynthesis and plant growth. Rubisco activase restores catalytic competence to Rubisco active sites by promoting the release of inhibitors in an ATP‐dependent manner.

Removal of Photosystem I Subunit PsaE Leads to Photosynthetic Hydrogen Production in a Cyanobacterial PsaF‐HoxYH Fusion Strain

Plant, Cell &Environment, EarlyView.
ABSTRACT Photosynthetic hydrogen (photoH2) production is a promising approach for the utilisation of solar energy. Fusion of a hydrogenase (H2ase) to photosystem I (PSI) provides a direct light‐driven route for photoH2 generation. We established the lateral transmembrane subunit PsaF of PSI as a new fusion partner for the NiFe‐hydrogenase (HoxYH) in ...

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

New Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.
