Cytochrome c oxidase inactivation in <i>Physcomitrium patens</i> reveals that respiration coordinates plant metabolism Open
Photosynthetic organisms use sunlight as an energy source but rely on respiration during the night and in nonphotosynthetic tissues. Respiration also occurs in photosynthetically active cells, where its role is still unclear due to the lac…

Oxygenic photosynthetic responses of cyanobacteria exposed under an M-dwarf starlight simulator: Implications for exoplanet’s habitability Open
Introduction The search for life on distant exoplanets is expected to rely on atmospheric biosignatures detection, such as oxygen of biological origin. However, it is not demonstrated how much oxygenic photosynthesis, which on Earth depend…

Regulation of electron transport is essential for photosystem I stability and plant growth Open
Summary Photosynthetic electron transport is regulated by cyclic and pseudocyclic electron flow (CEF and PCEF) to maintain the balance between light availability and metabolic demands. CEF transfers electrons from photosystem I to the plas…

Regulation of electron transport is essential for photosystem I stability and plant growth Open
Life depends on the ability of photosynthetic organisms to exploit sunlight to fix carbon dioxide into biomass. Photosynthesis is modulated by pathways such as cyclic and pseudocyclic electron flow (CEF and PCEF). CEF transfers electrons f…

Involvement of Potassium Transport Systems in the Response of<i>Synechocystis</i>PCC 6803 Cyanobacteria to External pH Change, High-Intensity Light Stress and Heavy Metal Stress Open
The unicellular photosynthetic cyanobacterium, able to survive in varying environments, is the only prokaryote that directly converts solar energy and CO2 into organic material and is thus relevant for primary production in many ecosystems…
