A chemosensory system that regulates biofilm formation through modulation of cyclic diguanylate levels.
TLDR
The data suggest that the wsp signal transduction pathway regulates biofilm formation through modulation of cyclic diguanylate levels.
THE β-KETOADIPATE PATHWAY AND THE BIOLOGY OF SELF-IDENTITY
TLDR
Accumulating evidence points to an independent and convergent evolutionary origin for the eukaryotic beta-ketoadipate pathway, which appears to assume a characteristic set of features or identity in different bacteria.
Identification of FleQ from Pseudomonas aeruginosa as a c‐di‐GMP‐responsive transcription factor
TLDR
The results show that FleQ is a new type of c‐di‐GMP binding protein that controls the transcriptional regulation of EPS biosynthesis genes in P. aeruginosa.
Complete genome sequence of the metabolically versatile photosynthetic bacterium Rhodopseudomonas palustris
TLDR
The genome sequence of R. palustris is described, which reveals genes that confer a remarkably large number of options within a given type of metabolism, including three nitrogenases, five benzene ring cleavage pathways and four light harvesting 2 systems.
The Pseudomonas aeruginosa RpoS regulon and its relationship to quorum sensing
TLDR
Transcription profiling results have allowed us to build a model that accommodates previous seemingly conflicting reports about RpoS function in P. aeruginosa and to understand better the regulation of quorum‐controlled genes, which highlights the significance of RPOS as a global factor that controls quorum-sensing gene expression at the onset of stationary phase.
The beta-ketoadipate pathway and the biology of self-identity.
TLDR
Accumulating evidence points to an independent and convergent evolutionary origin for the eukaryotic beta-ketoadipate pathway, which appears to assume a characteristic set of features or identity in different bacteria.
Anaerobic metabolism of aromatic compounds via the benzoyl‐CoA pathway
Aromatic compounds are important growth substrates for microorganisms. They form a large group of diverse compounds including lignin monomers, amino acids, quinones, and flavonoids. Aerobic aromatic
Pseudomonas aeruginosa Rugose Small-Colony Variants Have Adaptations That Likely Promote Persistence in the Cystic Fibrosis Lung
TLDR
A detailed comparison of clonally related wild-type and RSCV strains isolated from both CF sputum and laboratory biofilm cultures shows that RSCVs traits such as increased exopolysaccharide production leading to antibiotic tolerance, altered metabolism, and reduced immunogenicity may contribute to increased persistence in biofilms and in the airways of CF lungs.
Responses of Pseudomonas aeruginosa to low oxygen indicate that growth in the cystic fibrosis lung is by aerobic respiration
TLDR
Data is presented in favour of the alternative hypothesis that microaerobic respiration is the predominant mode of P. aeruginosa growth in the cystic fibrosis lung.
PcaK, a high-affinity permease for the aromatic compounds 4-hydroxybenzoate and protocatechuate from Pseudomonas putida
TLDR
Results show that although aromatic acids in the undissociated (uncharged) form can diffuse across bacterial membranes, high-specificity active transport systems probably also contribute to the ability of bacteria to grow on the micromolar concentrations of these compounds that are typically present in soil.
