Proteome analysis of Pectobacterium atrosepticum cells and inhibition effect of exogeneous treatment with lactonase.

ABSTRACT: The proteome of Pectobacterium atrosepticum cells was established by shotgun proteomics and compared to the proteome of the same bacterium treated with exogeneous lactonase to characterize the molecular modifications induced by the treatment with a quorum sensing inhibitor.

Quorum Quenching Lactonase Alters Virulence of Pectobacterium atrosepticum and Reduces Maceration in Potatoes.

Pectobacterium atrosepticum is a soft rot phytopathogenic bacterium mainly infecting potatoes. The virulence of P. atrosepticum is controlled by quorum sensing (QS), a communication mechanism which enables bacteria to coordinate their behavior in a population density-dependent manner. Inhibiting QS has gained interest as a sustainable alternative to conventional treatments to control pathogens in agriculture. Here, we investigate the potential of a robust lactonase to inhibit P. ...[more]

Proteome analysis of Bacillus cereus ATCC 14579 and its tspO mutant at late exponential and stationary phases

Project description:The proteomes of Bacillus cereus ATCC 14579 and its tspO mutant were established by label-free shotgun proteomics for cells harvested at late exponential and stationary phases. The comparative analysis indicated the molecular modifications induced by the phase transition and by the mutation of the gene encoding the transmembrane translocator protein TSPO which is a quorum sensing inhibitor.

Effect of Rosmarinic acid in Pseudomonas aeruginosa PAO1 at expression level

Project description:We report a next-generation sequencing of total RNA from Pseudomonas aeruginosa PAO1 grown in presence of rosmarinic acid (RA) 100mM. Data analysis in comparison with cells grown in absence of RA revealed that the plant compound RA induces a broad transcriptional response in this bacterium, quite similar to the quorum sensing response.

A transcriptome analysis of the Vibrio fischeri LuxR-LuxI regulon

Project description:Acyl-homoserine lactone (acyl-HSL) quorum sensing was first discovered in Vibrio fischeri where it serves as a key control element of the seven-gene luminescence (lux) operon. Since this initial discovery, other bacteria have been shown to control hundreds of genes by acyl-HSL quorum sensing. Until recently, it has been difficult to examine the global nature of quorum sensing in V. fischeri. However, the complete genome sequence of V. fischeri is now available and this has enabled us to use transcriptomics to identify quorum-sensing regulated genes and to study the quorum-controlled regulon of this bacterium. In this study, we used DNA microarray technology to identify over two-dozen V. fischeri genes regulated by the quorum sensing signal N-3-oxohexanoyl-L-homoserine lactone (3OC6-HSL).

A New Class of Homoserine Lactone Quorum Sensing Signals

Project description:Quorum sensing is a term used to describe cell-to-cell communication that allows cell density-dependent gene expression. Many Gram-negative bacteria use acyl-homoserine lactone (acyl-HSL) synthases to generate fatty acyl-HSL quorum sensing signals, which function with signal receptors to control expression of specific genes. The fatty acyl group is derived from fatty acid biosynthesis and provides signal specificity, but the variety of signals is limited. We have discovered that the photosynthetic bacterium Rhodopseudomonas palustris uses an acyl-HSL synthase to produce p-coumaroyl-HSL by using environmental p-coumaric acid rather than fatty acids from cellular pools. The bacterium has a signal receptor with homology to fatty acyl-HSL receptors that responds to p-coumaroyl-HSL to regulate global gene expression. We also found that p-coumaroyl-HSL is made by other bacteria including Bradyrhizobium BTAi1 and Silicibacter pomeroyi DSS-3. This discovery extends the range of possibilities for acyl-HSL quorum sensing and raises fundamental questions about quorum sensing within the context of environmental signaling. Keywords: Comparison of transcriptome profiles Transcriptome profiles between Rhodopseudomonas palustris cells grown in the in the presence or absence of pC-HSL were compared.
