“…Quorum sensing (QS) is a process that links gene expression to the cell density of microbial populations (Albuquerque and Casadevall, 2012;Borea et al, 2018). During growth and reproduction, microbial populations secrete and release some specific signaling molecules due to the increase in cell density, and the concentration of their secreted signaling molecules can reach a threshold when the cell density reaches a certain level, and the signaling molecules then strongly induce synchronized gene expression by binding to their homologous receptor proteins, thus initiating or shutting down specific population biological behaviors (Turan et al, 2017;Franco et al, 2021;Tian et al, 2021). QS occurs widely in many different bacteria, as well as some fungi and yeast (Jagtap et al, 2020).…”

“…The production of QSMs in S. cerevisiae depends on environmental factors, including cell density (Avbelj et al, 2015(Avbelj et al, , 2016, nitrogen content (Chen and Fink, 2006), ethanol (Avbelj et al, 2015), and aerobic/anaerobic growth conditions (Avbelj et al, 2016;Jagtap et al, 2020;Franco et al, 2021). These factors contribute to the production of QSMs, which trigger phenotypic changes to promote morphological adaptations to new environmental conditions.…”

Quorum sensing (QS) is one of the most well-studied cell-to-cell communication mechanisms in microorganisms. This intercellular communication process in Saccharomyces cerevisiae began to attract more and more attention for researchers since 2006, and phenylethanol, tryptophol, and tyrosol have been proven to be the main quorum sensing molecules (QSMs) of S. cerevisiae. In this paper, the research history and hotspots of QS in S. cerevisiae are reviewed, in particular, the QS system of S. cerevisiae is introduced from the aspects of regulation mechanism of QSMs synthesis, influencing factors of QSMs production, and response mechanism of QSMs. Finally, the employment of QS in adaptation to stress, fermentation products increasing, and food preservation in S. cerevisiae was reviewed. This review will be useful for investigating the microbial interactions of S. cerevisiae, will be helpful for the fermentation process in which yeast participates, and will provide an important reference for future research on S. cerevisiae QS.

Weapons against Themselves: Identification and Use of Quorum Sensing Volatile Molecules to Control Plant Pathogenic Fungi Growth

et al. 2022

Quorum sensing (QS) is often defined as a mechanism of microbial communication that can regulate microbial behaviors in accordance with population density. Much is known about QS mechanisms in bacteria, but fungal QS research is still in its infancy. In this study, the molecules constituting the volatolomes of the plant pathogenic fungi Fusarium culmorum and Cochliobolus sativus have been identified during culture conditions involving low and high spore concentrations, with the high concentration imitating overpopulation conditions (for QS stimulation). We determined that volatolomes emitted by these species in conditions of overpopulation have a negative impact on their mycelial growth, with some of the emitted molecules possibly acting as QSM. Candidate VOCs related to QS have then been identified by testing the effect of individual volatile organic compounds (VOCs) on mycelial growth of their emitting species. The antifungal effect observed for the volatolome of F. culmorum in the overpopulation condition could be attributed to ethyl acetate, 2-methylpropan-1-ol, 3-methylbutyl ethanoate, 3-methylbutan-1-ol, and pentan-1-ol, while it could be attributed to longifolene, 3-methylbutan-1-ol, 2-methylpropan-1-ol, and ethyl acetate for C. sativus in the overpopulation condition. This work could pave the way to a sustainable alternative to chemical fungicides.
