Regulation of photosynthetic electron transport in the thylakoid membrane of chloroplasts is fundamental for the maximum photosynthetic yield and plant growth. The light reactions in photosynthesis ...

Photosystem I (PSI) enables photo-electron transfer and regulates photosynthesis in the bioenergetic membranes of cyanobacteria and chloroplasts. Being a multi-subunit complex, its macromolecular ...

Annemarie Perez Boerema from Alexey Amunts lab has reconstructed the atomic models of new forms of Photosystem I in collaboration with scientists from Israel and China. The studies, published in two ...

A team of researchers led by Penn State scientists has identified the location of changes in the photosynthetic apparatus of some cyanobacteria—formerly known as "blue-green algae"—that allow the ...

We are aiming to explore electron transfer and binding mechanisms between the soluble electron transfer proteins plastocyanin or cytochrome c6 and photosystem I (PSI) (Finazzi et al., 2005; Sommer et ...

A new study provides the first insights into how thylakoid membranes—the internal compartments where oxygen-producing photosynthesis takes place—emerged during evolution. By comparing the genomes of ...

Photosystem I in plants shows a hitherto unknown face / Molecular examination with maximum precision Photosynthesis is the most important basis of life on Earth. In it, plants and single-cell algae ...

Scientists have decoded the atomic structure of Photosystem I from a 3-billion-year-old cyanobacteria lineage, offering a unique look at early oxygen-producing photosynthesis. The ancient nanodevice, ...

Cyclic electron transport around photosystem I (PSI) was discovered more than a half-century ago and two pathways have been identified in angiosperms. Recently, substantial progress has been made in ...
