Fungal genetics is the study of the mechanisms of heritable information in fungi. Yeasts and filamentous fungi are extensively used as model organisms for eukaryotic genetic research, including cell cycle regulation, chromatin structure, genetic recombination and gene regulation.
Nematode signals such as ascarosides are sensed by G protein-coupled receptors of a nematode-trapping fungus, resulting in fungal activation of cAMP–PKA signalling and trap development.
A laccase was found to act as a key component of environmental sensing in the fungal plant pathogen Sclerotinia sclerotiorum. This study demonstrates the role that this laccase plays in fungal cell wall architecture and virulence on plant tissue.
Bing et al. report that Candida auris undergoes rapid evolution via de novo genetic mutations and forms multicellular aggregates that exhibit a survival advantage over the single-celled yeast-form phenotype during host infection.
Whole-genome analysis of 876 Aspergillus fumigatus strains including 171 strains from Japan highlights the diversity in the A. fumigatus strains isolated in Japan as well as the complexity in the global distribution of the pathogenic strains.
The authors uncover the molecular mechanisms through which the arginine methyltransferase PRMT5 regulates the biosynthesis of secondary metabolites in the fungus Ganoderma lucidum.
In this Journal Club, Amelia Barber discusses a study revealing intraspecies heterogeneity in a fungal pathogen, prompting us to re-evaluate the notion of ‘reference’ strains.
Identification and analysis of mutator strains in the human fungal pathogen Cryptococcus neoformans show that natural loss of RNA interference triggers massive accumulation of Cnl1 retroelements at subtelomeric regions.
Computational analysis of fungal genomes revealed that some early-branching fungi use selenocysteine, the selenium-containing amino acid, that was thought to be missing from proteins in this lineage.
