A sensor kinase controls turgor-driven plant infection by the rice blast fungus
The histidine–aspartate kinase Sln1 acts as a molecular sensor of turgor in appressoria of the rice blast fungus Magnaporthe oryzae, enabling penetration of the host leaf cuticle and plant infection.

Candidalysin is a fungal peptide toxin critical for mucosal infection
This study identifies a cytolytic peptide toxin in the opportunistic human fungal pathogen Candida albicans—the peptide is both a crucial virulence factor that permeabilizes the host cell plasma membrane and a key signal that triggers a host danger response pathway.

Fungal pathogen uses sex pheromone receptor for chemotropic sensing of host plant signals
Fungal pathogens reorient hyphal growth towards their plant hosts in response to chemical signals; here, directed growth of the plant pathogen Fusarium oxysporum towards the roots of the tomato plant is shown to be triggered by class III peroxidases secreted by the tomato plant, with the fungal response requiring a sex pheromone receptor.

Antifungal drug resistance evoked via RNAi-dependent epimutations
The human fungal pathogen Mucor circinelloides develops spontaneous resistance to an antifungal drug both through mutation and through a newly identified epigenetic RNA-mediated pathway; RNA interference is spontaneously triggered to silence the fkbA gene, giving rise to drug-resistant epimutants that revert to being drug-sensitive once again when grown in the absence of drug.

Sudden larch death
An aggressive and unpredictable fungal pathogen is devastating larch plantations in Britain. Its remarkably broad host range, and the possibility of further geographical spread, give heightened cause for concern.

| Open AccessComparative genomics reveals mobile pathogenicity chromosomes in Fusarium
Fungi from the genus Fusarium are important pathogens of animals and crop plants. Some have a wide host range, whereas others are more specific in the organisms they infect. Here, clues are provided as to how differences in specificity come about. The genomes of two Fusarium fungi with differing host ranges have been sequenced, and compared with the genome of a third species. Experiments show that transferring two whole chromosomes turns a non-pathogenic Fusarium strain into a pathogenic one.
