Update on Photosynthetic Redox Control Novel Regulators in Photosynthetic Redox Control of Plant Metabolism and Gene Expression
Reduction-oxidation (redox) reactions are an essential part of cell metabolism and represent a major fraction of all catabolic and anabolic reactions. Their dominant characteristic is that they generate and consume compounds with in part highly negative redox potential. Redox reactions occur at many sites in the cell, e.g. in membranes such as thylakoids, plastid envelope, and plasma membrane a...
متن کاملRedox-state dynamics of ubiquinone-10 imply cooperative regulation of photosynthetic membrane expression in Rhodospirillum rubrum.
It is now well established that, for photosynthetic bacteria, the aerobic-to-microaerophilic transition activates the membrane-bound sensor kinase RegB, which subsequently phosphorylates the transcriptional activator RegA, thereby inducing elevated levels of intracellular photosynthetic membranes. The mechanism of RegB activation--in particular, the role of ubiquinone-10--is controversial at pr...
متن کاملPhotosynthetic electron transport regulates the expression of cytosolic ascorbate peroxidase genes in Arabidopsis during excess light stress.
Exposure of Arabidopsis plants that were maintained under low light (200 mumol of photons m-2 sec-1) to excess light (2000 mumol of photons m-2 sec-1) for 1 hr caused reversible photoinhibition of photosynthesis. Measurements of photosynthetic parameters and the use of electron transport inhibitors indicated that a novel signal transduction pathway was initiated at plastoquinone and regulated, ...
متن کاملSTN7 Operates in Retrograde Signaling through Controlling Redox Balance in the Electron Transfer Chain
Phosphorylation of the major photosynthetic light harvesting antenna proteins by STN7 kinase balances excitation between PSII and PSI. Phosphorylation of such abundant proteins is unique, differing distinctively from conventional tasks of protein kinases in phosphorylation of low abundance proteins in signaling cascades. Excitation balance between PSII and PSI is critical for redox homeostasis ...
