Quorum sensing (QS) allows bacteria to assess their local population density and/or physical confinement via the secretion and detection of small, diffusible signal molecules. This review describes how phytopathogenic bacteria have incorporated QS mechanisms into complex regulatory cascades that control genes for pathogenicity and colonization of host surfaces. Traits regulated by QS include the production of extracellular polysaccharides, degradative enzymes, antibiotics, siderophores, and… Expand
Quorum sensing and quorum quenching in soil ecosystems
TLDR
Several aspects of the quorum sensing phenomena, including sensitivity to both biotic and abiotic degradation, and the development of environmentally friendly procedures targeting QS regulation to reduce or suppress the aggressiveness of plant pathogens are reviewed. Expand
Quorum sensing, virulence and secondary metabolite production in plant soft-rotting bacteria
TLDR
The models for AHL-based regulation of carbapenem antibiotic production in Erwinia and the importance of quorum sensing in the production and secretion of virulence determinants by ErwinIA are reviewed and its interplay with other regulatory systems are discussed. Expand
Quorum Sensing Regulation in Phytopathogenic Bacteria
TLDR
The different quorum sensing systems present in phytopathogenic bacteria, such as those using the signal molecules named N-acyl-homoserine lactone (AHL), diffusible signal factor (DSF), and the unknown signal molecule of the virulence factor modulating (VFM) system are described. Expand
Quorum Sensing and Its Role in Agrobacterium Mediated Gene Transfer
Quorum sensing (QS) is a bacterial communication mechanism where individual cells produce and respond to small chemical signals. Literature reports activities such as conjugal transfer of the TiExpand
Shoot the messages not the messengers
TLDR
Experimental results strongly support the involvement of inter-bacterial communication in the rhizosphere by regulating quorum sensing (QS) by quorum-quenching (QQ) techniques and are of crucial importance for putting into practice sustainable disease-protection strategies for biocontrol technologies.

Plant-Microbial Interactions Involving Quorum Sensing Regulation
Quorum Sensing (QS) is a mechanism of bacterial intercellular communication that depends on their population density. QS activates the expression of hundreds of bacterial genes, many of which play anExpand

TLDR
Q-controlled beneficial traits in various plant-growth-promoting rhizobacterias (PGPRs) are reviewed, including production of antibiotics and lytic enzymes, phytosphere competence, the ability to promote plant growth, and induction of plant resistance to pathogens. Expand
Quorum Sensing in Plant Growth-Promoting Rhizobacteria and Its Impact on Plant-Microbe Interaction
TLDR
This chapter addressed the recent trends on the significance of quorum sensing and signal molecules in microbe-microbe and micro be-plant interactions in the rhizosphere with special reference to plant growth-promoting rhizobacteria and plant health. Expand
Quorum sensing as a target for developing control strategies for the plant pathogen Pectobacterium
TLDR
Approaches that have been developed to quench the quorum-sensing-dependent pathogenicity in Pectobacterium range from signal degradation by physicochemical constraints to the identification of signal-s sensing inhibitors and from the Identification of enzymes degrading acyl-homoserine lactones to the construction of transgenic plants tolerant to PectOBacterium.
