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 ...

Cyanobacteria began contributing oxygen to Earth's mostly noxious atmosphere more than 2 billion years ago. The photosystem II protein complex now shared by various lineages of cyanobacteria, algae ...

Oxygenic photosynthesis relies on two large multisubunit assemblies, photosystem II (PSII) and photosystem I (PSI), embedded within the thylakoid membrane. Each photosystem comprises a reaction centre ...

More than two billion years ago, cyanobacteria began producing oxygen in Earth’s primarily toxic atmosphere. Since then, the photosystem II protein complex—now shared by land plants, algae, and ...

Researchers from Okayama University have discovered rapid structural changes in the oxygen-evolving center of Photosystem II (PSII) upon light excitation, revealing insights into the mechanism of ...

The D2 polypeptide of the photosystem II (PSII) complex in the green alga Chlamydomonas reinhardtii is thought to be reversibly phosphorylated. By analogy to higher plants, the phosphorylation site is ...

In the recent decade, scientists have paid more attention to studying light harvest for producing novel bionic materials or integrating naturally biological components into synthetic systems.

Researchers have, with the help of cryogenic electron microscopy, succeeded in producing a high-resolution image of photosystem II - the central complex of photosynthesis - of the model plant ...

Many proteins of the photosynthesis complexes are encoded by the genome of the chloroplast and synthesized by bacterium-like ribosomes within this organelle. To determine where proteins are ...

Researchers at Washington University in St. Louis have traced the paths of three water channels in an ancient photosynthetic organism to provide the first comprehensive, experimental study of how that ...
