Inhibiting fungal multidrug resistance by disrupting an activator–Mediator interaction
A small molecule, inhibitor of a protein–protein interaction between the transcription factor Pdr1 and the Med15 subunit of Mediator in the fungal pathogen Candida glabrata, is identified and characterized here; the compound iKIX1 inhibits Pdr1-mediated gene activation and resensitizes drug-resistant C. glabrata to azole antifungals in vitro and in animal models of disseminated and urinary tract infection.

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.

Amphibians acquire resistance to live and dead fungus overcoming fungal immunosuppression
The fungal pathogen Batrachochytrium dendrobatidis has been implicated in the decline of a large number of amphibian species; here it is shown that frogs can learn to avoid the pathogen, acquire resistance to it and be immunized against it using dead pathogen, findings that potentially offer a way in which resistant populations could be reintroduced into areas that have seen catastrophic declines.

Convergent evolution of a fused sexual cycle promotes the haploid lifestyle
In the predominantly diploid yeast Saccharomyces cerevisiae, regulatory control of mating is separate from meiosis; here the related hemiascomycete yeast Candida lusitaniae is shown to have coordinated regulatory control of mating and meiosis, favouring the formation of haploids.

The ‘obligate diploid’ Candida albicans forms mating-competent haploids
Candida albicans is a prominent human fungal pathogen that until now was thought to be an obligate diploid; here it is shown that C. albicans can form viable haploids, that these haploids are able to mate to form heterozygous diploids, and that haploids and their auto-diploids are significantly less fit in vitro and in vivo than heterozygous progenitors or diploids formed by haploid mating pairs.

Fungal lipochitooligosaccharide symbiotic signals in arbuscular mycorrhiza
Nitrogen-fixing rhizobia use lipochitooligosaccharide (LCO) signal molecules to initiate a symbiotic relationship with plant roots. Although it has been suggested that mycorrhizal fungi also secrete chemical signals for this process, the identity of these molecules was unknown. It is now shown that like rhizobia, mycorrhizal fungi produce LCOs and that these molecules are important for the establishment of the symbiotic relationship between plant root and fungus.

Genome-wide measurement of RNA secondary structure in yeast
Experimental determination of the secondary structure of RNA molecules has usually been carried out on a case-by-case basis. Now, however, a deep-sequencing approach has been used to profile the secondary structure of 3,000 distinct messenger RNA transcripts from Saccharomyces cerevisiae. The results provide interesting hints about the role of secondary structure in protein translation, and set the stage for the examination of how such structures can change in response to environmental conditions.
