Fungal physiology is a scientific discipline that concerns the life-supporting functions and processes of fungi that allow fungal organisms to grow and reproduce.
Echinocandins are antifungal drugs that inhibit hyphal growth and induce lysis of hyphal tip compartments in pathogenic Aspergillus species. Here, Calise et al. show that echinocandins induce production of a fungal oxylipin signal, thus triggering hyphal growth changes that reduce hyphal tip lysis and confer echinocandin tolerance.
The authors uncover the molecular mechanisms through which the arginine methyltransferase PRMT5 regulates the biosynthesis of secondary metabolites in the fungus Ganoderma lucidum.
Pipercevic et al resolve how inositol molecules activate the VTC protein complex. The VTC complex stores phosphate in yeast and is controlled by SPX domains. The inositol molecules break an interaction between SPX domains to activate the complex.
This study reports that mycobiota-derived metabolites can feed pathogenic Salmonella enterica subsp. enterica serovar Typhimurium and promote its competitive advantage, thus revealing a role of the fungal community during bacterial infection.
