Induction of systemic resistance in tomato by N-acyl-L-homoserine lactone-producing rhizosphere bacteria.
N-acyl-L-homoserine lactone (AHL) signal molecules are utilized by Gram-negative bacteria to monitor their population density (quorum sensing) and to regulate gene expression in a density-dependent manner. We show that Serratia liquefaciens MG1 and Pseudomonas putida IsoF colonize tomato roots, produce AHL in the rhizosphere and increase systemic resistance of tomato plants against the fungal l...
متن کاملBiochemical Detection of N-Acyl Homoserine Lactone from Biofilm-Forming Uropathogenic Escherichia coli Isolated from Urinary Tract Infection Samples
Background: N-Acyl homoserine lactone (AHL) is found to be the main component of quorum sensing (QS) in Gram-negative bacteria and plays an important role in biofilm formation. Little information is available regarding the role of AHL in biofilm formation in Escherichia coli (E. coli). The purpose of this investigation was to biochemically detect and characterize AHL activity in biofilm-forming...
متن کاملN-acyl Homoserine Lactone-Producing Pseudomonas putida Strain T2-2 from Human Tongue Surface
Bacterial cell-to-cell communication (quorum sensing) refers to the regulation of bacterial gene expression in response to changes in microbial population density. Quorum sensing bacteria produce, release and respond to chemical signal molecules called autoinducers. Bacteria use two types of autoinducers, namely autoinducer-1 (AI-1) and autoinducer-2 (AI-2) where the former are N-acylhomoserine...
متن کاملAcyl-homoserine lactone degrading marine bacteria: Do they exist?
Acyl-homoserine lactones (acyl-HSL) are small molecules that are used in density dependent regulation in some bacteria. These molecules freely diffuse from the cell into the outside environment. Hence, it may be advantageous for other bacteria to utilize these molecules as a carbon source. The aim of this study is to look for acyl-HSL-utilizing bacteria in the marine environment. One strain, a ...
متن کاملCharacterisation of a Marine Bacterium Vibrio Brasiliensis T33 Producing N-acyl Homoserine Lactone Quorum Sensing Molecules
N-acylhomoserine lactones (AHL) plays roles as signal molecules in quorum sensing (QS) in most Gram-negative bacteria. QS regulates various physiological activities in relation with population density and concentration of signal molecules. With the aim of isolating marine water-borne bacteria that possess QS properties, we report here the preliminary screening of marine bacteria for AHL product...
