Imaging N-Acyl Homoserine Lactone Quorum Sensing In Vivo
2010In order to study N-acyl homoserine lactone (AHL)-based quorum sensing in vivo, we present a protocol using an Escherichia coli strain equipped with a luxR-based monitor system, which in the presence of exogenous AHL molecules expresses a green fluorescent protein (GFP).

Molecular mechanisms of N‐acyl homoserine lactone signals perception by plants
Cell Biology International, 2021AbstractN‐acyl homoserine lactones (AHLs) belong to the class of bacterial quorum sensing signal molecules involved in distance signal transduction between Gram‐negative bacteria colonizers of the rhizosphere, as well as bacteria and plants. AHLs synchronize the activity of genes from individual cells, allowing the bacterial population to act as a ...

Acyl-Homoserine Lactone Quorum Sensing: From Evolution to Application
Annual Review of Microbiology, 2013Quorum sensing (QS) is a widespread process in bacteria that employs autoinducing chemical signals to coordinate diverse, often cooperative activities such as bioluminescence, biofilm formation, and exoenzyme secretion. Signaling via acyl-homoserine lactones is the paradigm for QS in Proteobacteria and is particularly well understood in the ...

Acyl-Homoserine Lactone Biosynthesis: Structure and Mechanism
2014The first quorum-sensing system to be discovered was the Lux system of Vibrio fischeri, which regulates light production in the light organ of deep sea fish and squid via an acyl-homoserine lactone (AHL) signaling molecule. The LuxI-type AHL synthases catalyze the formation of the AHL from the substrates S-adenosyl-L-methionine (SAM) and acyl-acyl ...

Agrobacterium conjugation and gene regulation by N-acyl-L-homoserine lactones
Nature, 1993Conjugal opines secreted by crown gall tumours induce strains of Agrobacterium tumefaciens that are donors of Ti plasmids to produce a diffusible conjugation factor. This enhances the conjugal transfer efficiency of the Ti plasmid in other strains of A. tumefaciens.

The role of N-acyl homoserine lactones in maintaining the stability of aerobic granules
Bioresource Technology, 2014In this study, porcine kidney acylase, as N-acyl homoserine lactones (AHLs)-degradation enzyme, was employed for the first time to directly investigate the role of AHLs in the structure stability of aerobic granules. Results clearly showed that inactivation of AHLs by AHLs-acylase could weaken the stability of aerobic granule.

Acylated Homoserine Lactone Signaling in Marine Bacterial Systems
2014This chapter reviews the current understanding of acylated homoserine lactone (AHL) signaling in marine bacterial systems outside of the well-described Vibrio fischeriand Vibrio harveyi models. AHL production has far only been documented in proteobacterial groups.

Determination of Acyl Homoserine Lactone and Tetramic Acid Concentrations in Biological Samples
2010Within environmental communities, there is a constant struggle for survival, as nutrients are often limited. In response, bacteria have developed elaborate methods to deal with competitors. One such mechanism is the coordination of behaviors and function via the exchange of small chemical signals in a process known as quorum sensing.

Synthetic Agents for the Derivatization of N-Acyl Homoserine Lactones
2014Quorum sensing is a process of chemical communication in bacteria that enables bacteria to coordinate group function, including unified gene expression. As the quorum sensing mechanism is in part responsible for the virulent activity of many bacteria, inhibiting the communication pathway has the potential to lead to the development of novel antibiotics.
