A cell-cell signaling sensor is required for virulence and insect transmission of Xylella fastidiosa
Cell-cell signaling in Xylella fastidiosa, a xylem-colonizing plant pathogenic bacterium, mediated by a fatty acid Diffusible Signaling Factor (DSF), is required to colonize insect vectors and to s...
A Single Regulator Mediates Strategic Switching between Attachment/Spread and Growth/Virulence in the Plant Pathogen Ralstonia solanacearum
The PhcA virulence regulator in the vascular wilt pathogen Ralstonia solanacearum responds to cell density via quorum sensing. To understand the timing of traits that enable R. solanacearum to esta...
Causes and consequences of plant-associated biofilms
The rhizosphere is the critical interface between plant roots and soil where beneficial and harmful interactions between plants and microorganisms occur. Although microorganisms have historically b...
Decoding the genetic and functional diversity of the DSF quorum-sensing system in Stenotrophomonas maltophilia
Stenotrophomonas maltophilia uses the Diffusible Signal Factor (DSF) quorum sensing (QS) system to mediate intra- and inter-specific signaling and regulate virulence-related processes. The componen...
Diffusible signal factor-dependent quorum sensing in pathogenic bacteria and its exploitation for disease control
Cell-to-cell signals of the diffusible signal factor (DSF) family are cis-2-unsaturated fatty acids of differing chain length and branching pattern. DSF signalling has been described in diverse bac...
Insects as alternative hosts for phytopathogenic bacteria
Phytopathogens have evolved specialized pathogenicity determinants that enable them to colonize their specific plant hosts and cause disease, but their intimate associations with plants also predis...
Methylobacterium-Induced Endophyte Community Changes Correspond with Protection of Plants against Pathogen Attack
Plant inoculation with endophytic bacteria that normally live inside the plant without harming the host is a highly promising approach for biological disease control. The mechanism of resistance in...
Methylobacterium-plant interaction genes regulated by plant exudate and quorum sensing molecules
Bacteria from the genus Methylobacterium interact symbiotically (endophytically and epiphytically) with different plant species. These interactions can promote plant growth or induce systemic resis...
Quorum sensing and virulence regulation in Xanthomonas campestris
It is now clear that cell-cell communication, often referred to as quorum sensing (QS), is the norm in the prokaryotic kingdom and this community-wide genetic regulatory mechanism has been adopted ...
Quorum-sensing regulation governs bacterial adhesion, biofilm development, and host colonization in Pantoea stewartii subspecies stewartii
The phytopathogenic bacterium Pantoea stewartii subsp. stewartii synthesizes stewartan exo/capsular polysaccharide (EPS) in a cell density-dependent manner governed by the Esal/EsaR quorum-sensing ...
Reversible non-genetic phenotypic heterogeneity in bacterial quorum sensing
Bacteria co-ordinate their social behaviour in a density-dependent manner by production of diffusible signal molecules by a process known as quorum sensing (QS). It is generally assumed that in hom...
The DSF Family of Cell-Cell Signals: An Expanding Class of Bacterial Virulence Regulators
Many pathogenic bacteria use cell-cell signaling systems involving the synthesis and perception of diffusible signal molecules to control virulence as a response to cell density or confinement to n...
