PsbS‐dependent and ‐independent mechanisms regulate carotenoid‐chlorophyll energy coupling in grana thylakoids Open
In higher plants, PsbS is known to play a key role in the regulation of photosynthetic light harvesting. However, the molecular mechanism and role of electronic carotenoid–chlorophyll (Chl) interactions for the downregulation of excess exc…

A Cytosolic Bypass and G6P Shunt in Plants Lacking Peroxisomal Hydroxypyruvate Reductase Open
The oxygenation of ribulose 1,5-bisphosphate by Rubisco is the first step in photorespiration and reduces the efficiency of photosynthesis in C3 plants. Our recent data indicate that mutants in photorespiration have increased rates of phot…

Photometric screens identified Arabidopsis peroxisome proteins that impact photosynthesis under dynamic light conditions Open
Summary Plant peroxisomes function collaboratively with other subcellular organelles, such as chloroplasts and mitochondria, in several metabolic processes. To comprehensively investigate the impact of peroxisomal function on photosynthesi…

Proteome analysis of peroxisomes from dark‐treated senescent <i>Arabidopsis</i> leaves Open
Peroxisomes compartmentalize a dynamic suite of biochemical reactions and play a central role in plant metabolism, such as the degradation of hydrogen peroxide, metabolism of fatty acids, photorespiration, and the biosynthesis of plant hor…

NPQ<sub>(T)</sub>: a chlorophyll fluorescence parameter for rapid estimation and imaging of non‐photochemical quenching of excitons in photosystem‐II‐associated antenna complexes Open
In photosynthesis, light energy is absorbed by light‐harvesting complexes and used to drive photochemistry. However, a fraction of absorbed light is lost to non‐photochemical quenching (NPQ) that reflects several important photosynthetic p…

Limitations to photosynthesis by proton motive force-induced photosystem II photodamage Open
The thylakoid proton motive force (pmf) generated during photosynthesis is the essential driving force for ATP production; it is also a central regulator of light capture and electron transfer. We investigated the effects of elevated pmf o…
