Four paradigms of bacterial-fungal interactions based on different QS systems. (A) P. aeruginosa can inhibit the morphological transition of C. albicansfrom yeast to hyphae. Meanwhile, farnesol, produced by C. albicans, can induce the production of C4-HSL and PQS in P. aeruginosa biofilm mutants. (B) Adual-species biofilm formed by S. mutans and C. albicans exhibits higher cell counts and biomass. (C) In the antagonistic interaction between the soil-bornebacterium B. subtilis and the fungal plant pathogen S. scabies, heritable phenotypic variation in the bacterium is mediated by mutations in the ComQXPA QSsystem. (D) P. putida KT2440 secretes two extracellular adhesive proteins, LapA and LapF, to form a biofilm. The dimorphic fungus O. piceae uses farnesol as a QSMto regulate its morphological transition from yeast to hyphal form.
How do bacteria and fungi communicate? In #mBio, researchers we examine the intricate quorum sensing-based dialog between these 2 types of microbes, focusing on its role in microbial network assembly and ecosystem function. Read the review: asm.social/2QX
