Fisher MC, Henk DA, 2012, Sex, drugs and recombination: the wild life of Aspergillus, Vol: 21, Pages: 1305-1306, ISSN: 1365-294X
Throughout the eukaryotes, sexual reproduction is an almost universal phenomenon. However, within the Kingdom Fungi, this relationship is not so clear-cut. Fungi exhibit a spectrum of reproductive modes and life-cycles; amongst the better known species, sexual reproduction is often facultative, can be rare, and in over half of the known Ascomycota (the moulds) is unknown (Taylor et al. 1999). However, over the last decade, it has become apparent that many of these asexual mitosporic taxa undergo cryptic recombination via unobserved mechanisms and that wholly asexual fungi are, in fact, a rarity (Taylor et al. 1999, 2001; Heitman 2010). This revolution in our understanding of fungal sexuality has come about in two ways: Firstly, sexual reproduction leaves an imprint on fungal genomes by maintaining genes required for mating and by generating patterns of mutation and recombination restricted to meiotic processes. Secondly, scientists have become better at catching fungi in flagrante delicto. The genus Aspergillus is one such fungus where a combination of population genetics, genomics and taxonomy has been able to intuit the existence of sex, then to catch the fungus in the act and formally describe their sexual stages. So, why are sexy moulds exciting? One species in particular, Aspergillus flavus, is notorious for its ability to produce a diverse array of secondary metabolites, of which the polyketide aflatoxins (AF) are carcinogenic and others (such as cyclopiazonic acid) are toxigenic. Because of the predilection of A. flavus to grow on crops, such as peanuts, corn and cotton, biocontrol is widely used to mitigate infection by pre-applying nonaflatoxigenic (AF-) strains to competitively exclude the wild-type AF+ strains. However, the eventual fate in nature of these biocontrol strains is not known. In this issue of Molecular Ecology, Olarte et al. (2012) make an important contribution by using laboratory crosses of A. flavus to show that not only is AF highly herit

Henk DA, Fisher MC, 2012, The gut fungus Basidiobolus ranarum has a large genome and different copy numbers of putatively functionally redundant elongation factor genes, Vol: 7, ISSN: 1932-6203
Fungal genomes range in size from 2.3 Mb for the microsporidian Encephalitozoon intestinalis up to 8000 Mb for Entomophaga aulicae, with a mean genome size of 37 Mb. Basidiobolus, a common inhabitant of vertebrate guts, is distantly related to all other fungi, and is unique in possessing both EF-1alpha and EFL genes. Using DNA sequencing and a quantitative PCR approach, we estimated a haploid genome size for Basidiobolus at 350 Mb. However, based on allelic variation, the nuclear genome is at least diploid, leading us to believe that the final genome size is at least 700 Mb. We also found that EFL was in three times the copy number of its putatively functionally overlapping paralog EF-1alpha. This suggests that gene or genome duplication may be an important feature of B. ranarum evolution, and also suggests that B. ranarum may have mechanisms in place that favor the preservation of functionally overlapping genes.
Fisher MC, Farrer RA, 2011, Outbreaks and the emergence of novel fungal infections: Lessons from the panzootic of amphibian chytridiomycosis, Journal of Invasive Fungal Infections, Vol: 5, Pages: 73-81, ISSN: 1753-3783
Chytridiomycosis is a cutaneous infection of amphibians caused by the chytridiomycete fungal pathogen Batrachochytrium dendrobatidis (Bd). Despite being in a phylum not known for pathogenicity in vertebrates, Bd is now recognized as a primary driver of amphibian declines. Data show that this novel pathogen emerged in the 20th century to colonize amphibians worldwide. Such rapid emergence of a previously unrecognized pathogen illustrates many aspects of emerging fungal infections that threaten human health, namely long-distance human-mediated dispersal, multihost reservoirs, and altered virulence. In order to combat Bd, new tools have been developed to track its global spread and to analyze in parallel whole-genome diversity. This article details how such tools have applications to tracking and managing human fungal infections.

This article highlights some of the more notable persistent fungal diseases of our times. It draws attention to the emergence of new fungal pathotypes infecting food staple crops, due largely to modern agricultural practices, and to nascent fungal diseases decimating frog populations worldwide and killing hibernating bats in Northern USA. We invoke use of the basic disease triangle concept to highlight the "missing" data, with regards to pathogen and host biology and to the various environmental parameters which may dictate disease spread. Given these data "voids" we comment on the implementation of policy. We conclude with a series of recommendations for improved disease surveillance and reporting, the need for greater public awareness of these issues and a call for greater funding for fungal research. In so doing, we have exploited Magnaporthe oryzae and Batrachochytrium dendrobatidis as exemplar emerging infectious fungi. Our aim is to highlight the impact of emerging and emergent fungi on food security and, more broadly, ecosystem health. © 2011 British Mycological Society.
