A bacterial chaperone-usher pathway links interkingdom association to antimicrobial protection of a fungal partner
Antimicrobial compounds (AMCs) influence species-level composition of microbial communities, governing beneficial and pathogenic interactions with plant and mammalian hosts. Phenazine-1-carboxylic acid (PCA) is a bacterially produced, redox-active AMC abundant in the rhizosphere. A recent study discovered the PCA-susceptible fungus Aspergillus calidoustus can grow in PCA-abundant environments by…
