    Crh proteins catalyze crosslinking of chitin and glucan polymers in fungal cell walls. Here, Bi et al. show that a Crh protein from the phytopathogenic fungus Botrytis cinerea acts as a cytoplasmic effector and elicitor of plant defense, and plants expressing this gene exhibit reduced sensitivity to the pathogen.

    Mycelial fusion can favour fungal strains that exploit each other, but the mechanism is not well understood. Here, Grum-Grzhimaylo et al. show that different cheater lineages share similar deficiencies in initiating fusion that nevertheless enable them to preferentially obtain the benefits of fusion initiated by wild-type mycelia.

    The kinetochore is a multi-complex structure that helps attach chromosomes to spindle microtubules, ensuring accurate chromosome segregation during cell division. Kinetochores are thought to be evolutionarily conserved, but which components are conserved is unclear. Here, the authors report that some members of the fungal phylum of Basidomycota lack many conventional kinetochore linker proteins. Instead, they possess a human Ki67-like protein that bridges the outer part of the kinetochore to centromere DNA, which may compensate for the loss of a conventional linker.

    The fungal pathogen Candida auris is resistant to multiple drugs including the common antifungal fluconazole. Here, Iyer et al. identify a compound that potentiates fluconazole activity against C. auris in vitro and in vivo by inhibiting a major efflux pump and thus increasing intracellular fluconazole accumulation.

    The fungus Neurospora crassa is a model organism for the study of various biological processes, but it is not known to be infected by any viruses. Here, Honda et al. identify RNA viruses that infect N. crassa and examine viral replication and RNAi-mediated antiviral responses, thus establishing this fungus as a model for the study of host-virus interactions.

    The pathogen Batrachochytrium dendrobatidis (BD) associated with widespread amphibian declines is present in Europe but has not consistently caused disease-induced declines in that region. Here, the authors suggest that an endemic strain of BD with low virulence may protect the hosts upon co-infection with more virulent strains.

    Fusarium graminearum is a major fungal pathogen of cereals. Here the authors show that F. graminearum secretes an effector, Osp24, that induces degradation of the wheat TaSnRK1α kinase to promote disease while an orphan wheat protein, TaFROG1, can compete with Osp24 for binding to TaSnRK1α and protect it from degradation

    Biosynthesis of glycosylphosphatidylinositol (GPI) is essential for the integrity of the fungal cell wall. Here, the authors show that the natural product jawsamycin inhibits GPI biosynthesis by targeting a subunit of the fungal UDP-glycosyltransferase, and displays pronounced activity against pathogenic fungi of the order Mucorales.

    Some plants produce toxic isothiocyanates that protect them against pathogens. Here, Chen et al. show that the plant pathogenic fungus Sclerotinia sclerotiorum converts isothiocyanates into non-toxic compounds via glutathione conjugation and, more effectively, via hydrolysis to amines using an isothiocyanate hydrolase.

    The ecological niche of host-associated microbes is defined by both abiotic and biotic dimensions. Here the authors analyse published data on fungal and oomycete pathogens of plants, demonstrating that specialization can evolve independently on abiotic and biotic axes and that interactions with host plants reduce thermal niche breadth.

    Multicellularity is one of the major transitions in evolution. Here, authors use a model to show that compared to unicellular bacteria, multicellular fungi can more rapidly colonise immobile, nutrient poor resources because exoenzymes provide greater or longer lasting benefits to mycelial organisms.

    The immunomodulatory role of commensal gut fungi and interactions with bacteria remain unclear. Here, using germ-free mice colonized with defined species of bacteria and fungi, the authors find that fungal colonization induces changes in bacterial microbiome ecology while having an independent effect on innate and adaptive immunity in mice.

    Extracellular vesicles can carry immunoregulatory cytokines such as TGF-β. Here the authors use CD11b-deficient mice and macrophages to show that such vesicles carrying TGF-β are produced in response to Candida albicans infections and can limit the proinflammatory response partly via a positive feedback on TGF-β production by endothelial cells.

    The fungal plant pathogen Zymoseptoria tritici is a major threat to wheat yield. Here Seybold et al. show that Z. tritici can suppress immune responses not only in infected tissue but also on other leaves, a phenomenon termed “systemic induced susceptibility” that is correlated with systemic changes in metabolite accumulation.

    New fungicides are needed due to emerging resistance shown by crop pathogens. Here, the authors show that a mono-alkyl lipophilic cation protects plants from fungal pathogens by inhibiting fungal mitochondrial respiration, inducing production of reactive oxygen species, triggering fungal apoptosis, and activating innate plant defense.

    Genome dynamics allow cells to repair DNA double-strand breaks (DSBs), which are highly toxic DNA lesions. Here the authors reveal that in S. cerevisiae, Rad52 DNA repair proteins assemble in liquid droplets that work with dynamic nuclear microtubules to relocalize lesions to the nuclear periphery for repair.
