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 ...

In higher plants and green algae, photosystem II (PSII) usually combines with light harvesting complex II (LHCII) to form the PSII-LHCII supercomplex. Under low-light conditions, the PSII-LHCII ...

One longstanding puzzle concerning photosystem II, a core component of photosynthesis, is that only one of the two symmetric branches in its reaction centre is active in electron transfer. To ...

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 ...

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 ...

This is a preview. Log in through your library . Abstract The heart of oxygenic photosynthesis is photosystem II (PSII), a multisubunit protein complex that uses solar energy to drive the splitting of ...

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 ...

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 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 ...
