Project

Ultrafast non-photochemical quenching in photosynthesis (GA24-11344S)

The project aims at elucidating the molecular mechanisms of ultrafast non-photochemical quenching in some photosynthetic proteins by means of ultrafast laser, the high-light induced proteins (Hlips). Some Hlips exhibit effi...

Regulation of the non-photochemical quenching and light photosynthetic reactions - the role of ion fluxes in the cell and in the chloroplast (GP206/09/P094)

The non-photochemical quenching (NPQ) is mechanism that protects photosytem II against excessive radiation. This finely tuned mechanism is controlled mostly by acidification of chloroplast lumen. The proton transport is cou...

Photoprotective antenna protein dynamics from live cells to algal proteoliposomes. (GJ17-02363Y)

The mechanisms of photoprotection in algae is still poorly understood in comparison to higher plants. The aim of the present proposal is to apply previous knowledge from higher plants (Belgio et al. Nature Comm. 2014) to new model organisms from alga...
