Rethinking the influence of chloroplast movements on non-photochemical quenching and photoprotection
plant cell chloroplast photoprotective mechanism non-photochemical quenching (NPQ)
2024/1/19
Under blue light, plant chloroplasts relocate to different areas of the cell. The photoreceptor phototropin 2 (phot2) mediates the chloroplast movement mechanism under excess blue light alongside the ...
Chloroplast-derived photo-oxidative stress causes changes in H2O2 and EGSH in other subcellular compartments
photo-oxidative stress chloroplast H2O2 EGSH stress acclimation redox dynamics
