Phytoplankton, such as diatoms, experience great variations of photon flux density (PFD) and light spectrum along the marine water column. Diatoms have developed some rapidly-regulated photoprotective mechanisms, such as the xanthophyll cycle activat

Photosynthesis in plants starts with the capture of photons by light-harvesting complexes (LHCs). Structural biology and spectroscopy approaches have led to a map of the architecture and energy transfer pathways between LHC pigments. Still, controver

Rethinking the Influence of Chloroplast Movements on Non-photochemical Quenching and Photoprotection

Autor: Samuel H. Wilson, Alexander V. Ruban

Publikováno v: Plant Physiol

Under blue light, plant chloroplasts relocate to different areas of the cell. The photoreceptor phototropin2 (phot2) mediates the chloroplast movement mechanism under excess blue light alongside the chloroplast unusual positioning1 (chup1) protein. R

Quantifying the long-term interplay between photoprotection and repair mechanisms sustaining photosystem II activity

Autor: Francesco Saccon, Sam Wilson, Felix S. Morey-Burrows, Alexander V. Ruban

Publikováno v: The Biochemical journal. 479(5)

The photosystem II reaction centre (RCII) protein subunit D1 is the main target of light-induced damage in the thylakoid membrane. As such, it is constantly replaced with newly synthesised proteins, in a process dubbed the ‘D1 repair cycle’. The
