Marine picocyanobacteria of the genera Prochlorococcus and Synechococcus numerically
dominate the picophytoplankton of the world ocean, making a key contribution to global …

Abstract The Crp-Fnr regulators, named after the first two identified members, are DNA-
binding proteins which predominantly function as positive transcription factors, though roles …

Cyanobacteria are equipped with numerous mechanisms that allow them to survive under
conditions of nutrient starvation, some of which are unique to these organisms. This review …

Cyanobacteria are one of the earliest branching groups of organisms on the planet, and
during their evolutionary history were submitted to varying selective pressures. Nowadays …
