Heat and water deficit stresses tend to impede and restrict the efficiency of photosynthesis, chlorophyll fluorescence and maximum photochemical quantum yield in plants based on their characteristic ...

Recognition of photodamaged D1 reaction center protein through Trp oxidation enables FtsH enzymatic degradation. Researchers from Okayama University, Japan, report the details of the photosystem-II ...

To assess the physiological significance of polyphenols as antioxidants in planta, we compared the kinetics of polyphenols oxidation with the inhibition of the photosynthetic apparatus in sunflower ...

Photosystem II (PSII) is a multisubunit complex, which uses light energy to split water into oxygen, protons, and electrons. The light-harvesting complex of PSII (LHCII) functions in the capture of ...

Photosynthesis plays a crucial role in shaping and sustaining life on Earth, yet many aspects of the process remain a mystery. One such mystery is how Photosystem II, a protein complex in plants, ...

Most plants split water molecules to generate energy, and now we have a clearer picture of exactly how they do it. Researches have found missing steps in photosynthesis by stimulating plant proteins ...
