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 ...

Photosystem II is the essential protein complex that drives the initial photochemical conversion of solar energy by catalysing the oxidation of water, an indispensable process in oxygenic ...

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 ...

Sujith Puthiyaveetil (left) and Steven McKenzie look at a plant thylakoid preparation in the lab at Purdue University's Biochemistry Building. WEST LAFAYETTE, Ind. — Cyanobacteria began contributing ...

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 ...

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 ...

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, ...

The conversion of light into chemical energy by plants and photosynthetic microorganisms is one of the most important processes in nature, removing climate-damaging CO2 from the atmosphere. Protein ...

Krause, G. Heinrich, Schmude, Claudia, Garden, Hermann, Koroleva, Olga Y., and Winter, Klaus. 1999. "Effects of Solar Ultraviolet Radiation on the Potential ...

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 ...
