Filamentous, heterocyst-forming cyanobacteria are among the simplest multicellular systems in Nature. In the absence of combined nitrogen, the filaments consist of vegetative cells that fix CO2 through oxygenic photosynthesis and micro-oxic...

Caulobacter crescentus is a free-living Alphaproteobacterium that thrives in oligotrophic environments. This review focuses on the regulatory network used by this bacterium to control the levels of cell division proteins, their organization...
Post-transcriptional control of virulence gene expression in Staphylococcus aureus [0.03%]
金黄色葡萄球菌中调控毒力基因表达的转录后机制

Opportunistic pathogens have to be ready to change life-style whenever the occasion arises, and therefore need to keep tight control over the expression of their virulence factors. Doubly so for commensal bacteria, such as Staphylococcus au...
Pseudomonas aeruginosa zinc homeostasis: Key issues for an opportunistic pathogen [0.03%]

Zinc is an essential trace element for almost all living organisms. In the opportunistic bacterial pathogen Pseudomonas aeruginosa, zinc has been shown to play an important role in virulence, in colonization of the host organism and has als...

The decision to initiate DNA replication is a critical step in the cell cycle of all organisms. In nearly all bacteria, replication initiation requires the activity of the conserved replication initiation protein DnaA. Due to its central ro...

Cell-to-cell differences in bacterial gene expression can merely reflect the occurrence of noise. In certain cases, however, heterogeneous gene expression is a programmed event that results in bistable expression. If bistability is heritabl...
