Recent advances in various 'omics' technologies enable quantitative monitoring of the
abundance of various biological molecules in a high-throughput manner, and thus allow …

Under a shortage of oxygen, bacterial growth can be faced mainly by two ATP-generating
mechanisms:(i) by synthesis of specific high-affinity terminal oxidases that allow bacteria to …

The anoxygenic phototrophic bacterium Rhodobacter sphaeroides uses different energy
sources, depending on environmental conditions including aerobic respiration or, in the …

The processes underlying the evolution of regulatory networks are unclear. To address this
question, we used a comparative genomics approach that takes advantage of the large …

Photosynthesis is a crucial biological process that depends on the interplay of many
components. This work analyzed the gene targets for 4 transcription factors: FnrL, PrrA, CrpK …

Anoxygenic photosynthesis is an important pathway for Rhodobacter sphaeroides to
produce ATP under oxygen-limiting conditions. The expression of its photosynthesis genes …

Transcriptional regulatory networks (TRNs) program cells to dynamically alter their gene
expression in response to changing internal or environmental conditions. In this study, we …

Abstract Background The genus Rhodobacter contains purple nonsulfur bacteria found
mostly in freshwater environments. Representative strains of two Rhodobacter species, R …

The two-component system RhpRS was identified in Pseudomonas syringae as a regulator
of the genes encoding the type III secretion system and type III effector proteins (together …

Purple nonsulfur bacteria adapt their physiology to a wide variety of environmental
conditions often through the control of transcription. One of the main transcription factors …
