Population density-dependent expression of luminescence in Vibrio fischeri is controlled by the autoinducer N-3-oxohexanoyl-L-homoserine lactone (autoinducer 1 [AI-1]), which via LuxR activates transcription of the lux operon (luxICDABEG, encoding the putative autoinducer synthase [LuxI] and the luminescence enzymes). We recently

In order to perform single-cell analysis and online studies of N-acyl homoserine lactone (AHL)-mediated communication among bacteria, components of the Vibrio fischeri quorum sensor encoded by luxR-P(luxI) have been fused to modified versions of gfpmut3* genes encoding unstable green fluorescent

Bacterial communities undergo collective behavioural switches upon producing and sensing diffusible signal molecules; a mechanism referred to as Quorum Sensing (QS). Exemplarily, biofilm organic matrices are built concertedly by bacteria in several environments. QS scope in bacterial ecology has been
Role of RpoS in stress resistance, quorum sensing and spoilage potential of Pseudomonas fluorescens.
Xiaoxiang Liu et al.
International journal of food microbiology, 270, 31-38 (2018-02-23)
Microorganism activities are considered the main cause of most food spoilage, leading to great economic losses. Pseudomonas fluorescens is a Gram-negative bacterium that is widely found in food and has high spoilage activity. RpoS is considered an important global regulator
