Expression data from Burkholderia cepacia IST408 bceE and bceF mutants

(Submitter supplied) The bacterial tyrosine (BY) kinase family comprises the major group of bacterial enzymes endowed with tyrosine kinase activity. We have previously shown that the BceF protein from Burkholderia cepacia IST408 belongs to this BY kinase family and is involved in the biosynthesis of the exopolysaccharide cepacian. However, little is known about the extent of regulation in the cell by this kinase protein. more...

Expression data from Burkholderia multivorans mucoid and nonmucoid isolates

(Submitter supplied) Burkholderia multivorans comprises opportunistic bacteria infecting hosts such as cystic fibrosis (CF) patients. Bcc long-term infection of CF patient airways has been associated with emergence of phenotypic variation including the mucoid-to-nonmucoid colony morphotype. Here we studied three Burkholderia multivorans clonal isolates (mucoid D2095 (BM11L), and nonmucoid D2214G and D2214P) and a laboratory nonmucoid variant (BM11L-nmv1) obtained under prolonged stationary phase. more...

Overexpression of a histone-like nucleoid structuring protein in Burkholderia multivorans affects several traits dependent on the cell envelope

(Submitter supplied) Burkholderia cepacia complex bacteria comprise opportunistic pathogens causing chronic respiratory infections in cystic fibrosis (CF) patients. These microorganisms produce exopolysaccharides which are considered virulence determinants. Here, we report the isolation of an evolved nonmucoid variant (17616nmv) after the ancestor, Burkholderia multivorans ATCC 17616, was subjected to prolonged stationary phase. more...

Hybridization of Burkholderia multivorans D2095 and D2214 genomic DNA

(Submitter supplied) Burkholderia cepacia complex (Bcc) comprises opportunistic bacteria infecting hosts such as cystic fibrosis (CF) patients. Bcc long-term infection of CF patient airways has been associated with emergence of phenotypic variation. Here we studied two Burkholderia multivorans clonal isolates (D2095 and D2214) displaying different morphotypes from a chronically infected CF patient in order to evaluate traits development during lung infection. more...

BolA is a transcriptional switch that turns off motility and turns on biofilm development

(Submitter supplied) Bacteria are extremely versatile organisms which rapidly adapt to changing environments. When Escherichia coli cells switch from planktonic growth to biofilm, flagellum formation is turned off, and the production of fimbriae and extracellular polysaccharides is switched on. Here we show that BolA protein is a new bacterial transcription factor which modulates the switch from planktonic to sessile lifestyle. more...

Expression data from Burkholderia multivorans ATCC 17616 wild-type and Bmul_2557 (ldhR) gene deletion mutant

(Submitter supplied) Within this work we identified and characterized gene Bmul_2557 (ldhR) of B. multivorans ATCC 17616, a bacterial species associated with chronic respiratory infections in cystic fibrosis patients. LdhR belongs to the LysR-type family of transcriptional regulators and its deletion from the B. multivorans genome affected considerably the formation of planktonic cellular aggregates and surface-attached biofilms.

Gene expression analysis of rel knockout and dcpA knockout strains of Mycobacterium smegmatis MC2 155

(Submitter supplied) The experiment was carried out to study the effect of loss of (p)ppGpp or cyclic di-GMP on the gene expression pattern of Mycobacterium smegmatis MC2 155 strains. The cells were cultured in MB7H9 broth containing 0.2% glycerol and 0.05% Tween 80. The transcriptome analysis was performed using GeneSpring GX12 software. Fold changes were calculated with respect to the median expression of wild type replicates. more...

High intracellular c-di-GMP levels antagonize quorum sensing and virulence gene expression in Burkholderia cenocepacia H111

(Submitter supplied) In this study, we have analysed the transcriptional profile of B. cenocepacia H111 upon artificially altering the global cellular c-di-GMP levels. A total of 111 genes was found to be differentially expressed, of which 96 genes were down-regulated when c-di-GMP concentrations were increased. The BDSF, AHL and c-di-GMP regulons overlap for the regulation of 24 genes. Intriguingly, at a high intracellular c-di-GMP level expression of the AHL synthase cepI was found to be more than 10-fold down-regulated. more...

Francisella Expression Microarray Analysis

(Submitter supplied) Francisella tularensis is a Gram-negative bacterium that is highly virulent in humans, causing the disease tularemia. F. novicida is closely related to F. tularensis and exhibits high virulence in mice, but is avirulent in healthy humans. A F. novicida-specific gene cluster (FTN0451-FTN0456) encodes two proteins with diguanylate cyclase (DGC) and phosphodiesterase (PDE) domains that modulate synthesis and degradation of cyclic di-GMP (cdGMP). more...
