Population Evidence of Cryptic Species and Geographical Structure in the Cosmopolitan Ectomycorrhizal Fungus, Tricholoma scalpturatum
TLDR
This result provides evidence for limited gene flow and/or founding effects, and indicates that T. scalpturatum does not constitute a random mating population, and the hypothesis of endemism cannot be excluded for this cosmopolitan wind-dispersed fungus. Expand
High sexual reproduction and limited contemporary dispersal in the ectomycorrhizal fungus Tricholoma scalpturatum: new insights from population genetics and spatial autocorrelation analysis
TLDR
These results clearly demonstrate high sexual reproduction and spatial structuring of genets at very small geographical scales in this wind‐dispersed ectomycorrhizal fungal species, a pattern consistent with restricted contemporary dispersal of spores. Expand
Presymbiotic growth and sporal morphology are affected in the arbuscular mycorrhizal fungus Gigaspora margarita cured of its endobacteria
TLDR
How a protocol based on repeated passages through single‐spore inocula caused dilution of the initial bacterial population eventually leading to cured spores is reported, which is the first manipulated and stable isolate of an arbuscular mycorrhizal fungus. Expand
Characterisation and expression analysis of a nitrate transporter and nitrite reductase genes, two members of a gene cluster for nitrate assimilation from the symbiotic basidiomycete Hebeloma
TLDR
These two genes are divergently transcribed and linked to a previously cloned nitrate reductase gene, thus demonstrating that nitrate assimilation gene clusters occur in homobasidiomycetes, and distinguish fungal high-affinity transporters from their plant homologues. Expand
Isolation, free-living capacities, and genome structure of "Candidatus Glomeribacter gigasporarum," the endocellular bacterium of the mycorrhizal fungus Gigaspora margarita.
TLDR
The data suggest that "Ca. Glomeribacter gigasporarum" is an ancient obligate endocellular bacterium of the AM fungus G. margarita, and its genome is the smallest genome known for a beta-proteobacterium. Expand
Transcription of a nitrate reductase gene isolated from the symbiotic basidiomycete fungus Hebeloma cylindrosporum does not require induction by nitrate
TLDR
High levels of transcription are observed in the presence of either very low nitrogen concentrations or high concentrations of nitrate or organic N sources such as urea, glycine or serine, which indicates that in H. cylindrosporum, in contrast to all nitrophilous organisms studied so far, an exogenous supply of nitrates is not required to induce transcription of a nitrate reductase gene.

Phylogenetic species delimitation in ectomycorrhizal fungi and implications for barcoding: the case of the Tricholoma scalpturatum complex (Basidiomycota)
TLDR
A library of taxonomically verified voucher specimens, an a posteriori correlation between phenotype and genotype, and DNA barcoding of ectomycorrhizal fungi are contributed to. Expand
What determines Alnus-associated ectomycorrhizal community diversity and specificity? A comparison of host and habitat effects at a regional scale.
TLDR
It is confirmed that Alnus ECM communities are low in diversity, highly conserved at a regional scale, and partly shared between congeneric host species and subgenus, and a large part of alpha and beta diversity variations remained unexplained. Expand
Population dynamics of the ectomycorrhizal fungal species Tricholoma populinum and Tricholoma scalpturatum associated with black poplar under differing environmental conditions.
TLDR
The genetic analyses revealed differences in local population dynamics between the two species, with Tricholoma scalpturatum tended to capture new space through sexual spores whereas T. populinum did this by clonal growth, suggesting trade-offs in allocation of resources at the genet level. Expand
Specific, non-nutritional association between an ascomycete fungus and Allomerus plant-ants
TLDR
Results suggest that an interaction involving Allomerus plant-ants that build galleried structures on their myrmecophytic hosts in order to ambush prey might represent an as-yet undescribed type of specific association between ants and fungus in which the ants cultivate fungal mycelia to strengthen their hunting galleries.
