The Role of Diffusible Signal Factors in Quorum Sensing for Improved Biocontrol Techniques

Abstract

Quorum sensing (QS) is a mechanism by which bacteria communicate with each other to coordinate group behavior. One important aspect of QS is the production and detection of diffusible signal factors (DSFs), which are small molecules that can diffuse across bacterial membranes and trigger various responses. DSFs have been shown to play a crucial role in regulating a wide range of biological processes, including biofilm formation, virulence, and antibiotic resistance. In recent years, researchers have started to explore the potential of DSFs in biocontrol applications, where they can be used to interfere with the communication and coordination of pathogenic bacteria. This review discusses the role of DSFs in QS and how they can be utilized to develop improved biocontrol techniques. We also discuss the various strategies that have been developed to interfere with DSF-mediated QS, such as using DSF analogs or enzymes that degrade DSFs. We highlight some of the promising applications of DSFs in biocontrol, including their use as biocontrol agents as part of plant microbiomes. We argue that DSFs represent a promising avenue for developing novel and effective biocontrol strategies that can help address some of the most pressing challenges in agriculture and healthcare.
