ProteomicsProteomic comparison of Arabidopsis thylakoid membranes: wild-type with genotypes hope2 and pgr5
The light reactions of photosynthesis couple electron and proton transfers across the thylakoid membrane, generating NADPH for carbon fixation and a proton motive force (dominated by ΔpH in chloroplasts) to drive ATP production by the ATP synthase complex. Regulation of NADPH and ATP levels to meet ...

Proteomicspgr5 suppressor screen uncovers a distinct mechanism safeguarding the cytochrome b6f complex from damage through PGR5
PROTON GRADIENT5 (PGR5) is thought to promote cyclic electron flow (CEF) and its deficiency causes increased photosensitivity of photosystem I (PSI), leading to lethality under fluctuating light (FL). By screening for suppressor mutations that rescue FL lethality of pgr5 plants, we identified a port...

We focused on Arabidopsis chloroplast ascorbate peroxidases (sAPX and tAPX) and proton gradient regulation 5 (PGR5) and used pgr5 single mutant, sapx tapx double mutant, and sapx tapx pgr5 triple mutant for RNA-seq analysis.

ProteomicsProteomic analysis of different pgr5 mutants and pgrl1ab in Arabidopsis thaliana
PGR5 is a small chloroplast protein that performs cyclic electron flow (CEF) around photosystem I and it is required for the proton gradient generation across the thylakoid membrane. The level of this protein is closely regulated by PGRL1. However, the molecular mechanism of PGR5 is still elusive. I...
