Many Gram-negative bacteria use quorum sensing (QS) signal molecules to monitor their local population density and coordinate collective behaviors. The diffusible factor (DSF) family represents an intriguing type of QS mediate intraspecies interspecies communication. Recently, accumulating evidence demonstrates the role DSF in mediating inter-kingdom communication between DSF-producing plants. However, regulatory mechanism during Xanthomonas-plant interactions remain unclear.Plants were pretreated with different concentration subsequent inoculated pathogen Xanthomonas campestris pv. (Xcc). Pathogenicity, phynotypic analysis, transcriptome combined metabolome genetic analysis gene expression used evaluate priming effects on plant disease resistance.We found that low could prime immunity against Xcc both Brassica oleracea Arabidopsis thaliana. Pretreatment invasion triggered augmented burst ROS by DCFH-DA DAB staining. CAT application attenuate level induced DSF.

Transcriptome showed hormone jasmonic acid (JA) signaling involved DSF-primed resistance Arabidopsis.

Quorum sensing (QS) is a bacterial communication method closely linked with population density and regulates biofilm formation the secretion of virulence factors through release, recognition, prompt response to small molecule signals. At low cell density, each bacterium produces concentration QS signals that diffuse or are actively transported into external environment. The accumulated in environment reach threshold when attains certain enabling effective recognition interaction their receptors. This leads coordinated gene expression various biological activities across population.

Free fatty acids (FFAs) have long been acknowledged for their antimicrobial activity. More recently, long-chain FFAs (>12 carbon atoms) are receiving increased attention potent antivirulence activity against pathogenic bacteria. In the gastrointestinal tract, foodborne pathogens encounter a variety of derived from diet, metabolic activities gut microbiota, or host. This review highlights role as signaling molecules acting to inhibit infectious potential important pathogens, including Salmonella and Listeria monocytogenes. Various interact with sensory proteins transcriptional regulators controlling expression infection-relevant genes. Consequently, may act disarm bacterial virulence factors. Understanding how sense respond enable design new anti-infective approaches.
