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 ...
Rapid photoprotection in sea-ice diatoms from the East Antarctic pack ice
Rapid photoprotection sea-ice diatoms the East Antarctic pack ice
2014/4/17
Photoinhibition and D1 protein re-synthesis were investigated in bottom-dwelling sea-ice microalgal communities from the East Antarctic pack ice during early spring. Bottom-dwelling sea-ice microalgal...
Photoprotection mechanisms against ultraviolet radiation in Heterocapsa sp. (Dinophyceae) are influenced by nitrogen availability: Mycosporine-like amino acids vs. xanthophyll cycle
Heterocapsa sp Photoprotection mechanisms
2014/4/16
The photoprotective and acclimation capacity against ultraviolet radiation (UVR) was assessed for the
dinoflagellate Heterocapsa sp. We examined the effect of UVR and N availability on photosynthetic...
Photoprotection capacity differs among diatoms: Possible consequences on the spatial distribution of diatoms related to fluctuations in the underwater light climate
Photoprotection capacity among diatoms spatial distribution diatoms related to fluctuations underwater light climate
2014/4/22
In this study, we show a fundamental difference between diatom species from different marine habitats in their ability to cope with changes in irradiance. Estuarine species show a higher and more flex...
Increased sensitivity to ultraviolet radiation in nitrogen-limited dinoflagellates: Photoprotection and repair
Increased sensitivity ultraviolet radiation nitrogen-limited dinoflagellates Photoprotection and repair
2014/5/26
Nitrogen (N) limitation significantly increased the sensitivity of photosynthesis to inhibition by ultraviolet radiation (UV) in two estuarine dinoflagellates, Akashiwo sanguinea (= Gymnodinium sangui...
