TL;DR: The ultrastructural study showed that chitosan caused deep erosion of the cell wall as well as increasing the cell-wall thickness, and this may well upset the balance between biosynthesis turnover of chitin, thereby rendering the cell walls more viscoelastic.

TL;DR: Sclerotia are loosely described as morphologically variable, nutrient-rich, multihyphal structures which can remain dormant or quiescent when their environment is adverse and then, when conditions improve, germinate to reproduce the fungus.

TL;DR: The wide array of developmental mutations described for Neurospora in this review should be a valuable resource for future research into the control of sexual development.

TL;DR: The principles governing translocation in rhizomorphs of ectomycorrhizal and saprotrophic basidiomycetes are similar, and it is suggested that rapid acropetal translocation of carbon occurs along part of the rhizomorphic length by a turgor-driven mass flow of solution in the apoplast of empty ‘vessel’ hyphae.

TL;DR: C. minitans will survive and spread in soil for at least 2 yr and continue to give some control of disease but details of its ecology are still uncertain, and the reasons for the lack of commercial interest in this biological control agent are discussed.

TL;DR: Four other species of Phakopsora and five species of Cerotelium parasitize legumes, each of which has either a Malupa, Milesia or Physopella anamorph are included.

TL;DR: A highly significant correlation was found between two ligninolytic indicators: ethene formation from α-keto-γ-methylthiolbutyric acid and the decolorization of a polymeric dye, Poly R.

TL;DR: The results indicate that VA mycorrhizal fungi respond differently according to the host species and thus such differences could result in selection pressures which favour certain host-fungus combinations.

TL;DR: Genetic variation among isolates of Beauveria spp.

TL;DR: The bioactive constituents of extracts of three strains of balsam fir endophytic fungi, reported to cause reduced growth rate and mortality of spruce budworm larvae, have been isolated and characterized, in the first report of the identification of toxins from fungal endophytes of woody plants.

TL;DR: The studies suggest that adhesion of nematodes to A. oligospora involves a recognition event using a lectin-carbohydrate interaction which might trigger the reorganization of the surface polymer layer and release of enzymes, leading to the firm binding of the nematode.

TL;DR: Results indicate that the magnitude of the disturbance regulates the rate of recovery not only of the vegetation, but also of both the VA and ectomycorrhizal fungi.

TL;DR: The continuous flow culture system currently used for myco-protein production is described, together with details of the ‘evolution’ of the fungus in prolonged culture.

TL;DR: A critical length of mycorrhizal root was found to be associated with the onset of sporulation for both fungi and for each fungus there was not a close relationship between the length of external hyphae and the number of spores produced.

TL;DR: The effects of mutations in the FBF and THN genes indicate that these differentially regulated hydrophobins may play a key role in the emergence of aerial structures while different hydrophOBins may determine specific hyphal-surface properties.

TL;DR: Fusarium species were isolated from grassland soil samples from four areas located along the Tropic of Capricorn between Rockhampton on the east coast and Boulia on the margin of the Simpson Desert in Queensland, Australia by plating root debris on Selective Fusarium Agar, and by the dilution plate technique on peptone PCNB agar.

TL;DR: The Mucorales are the only fungal group where ferritin has been detected so far, suggesting that the substitution of hydroxamate siderophores by complexone siderophile has led to the formation of ferritins as the eucaryotic iron storage proteins.

TL;DR: An ultrastructural study of infection of Arabidopsis thaliana with Plasmodiophora brassicae with the development of secondary plasmodia from myxamoebae is reported.

TL;DR: Although N. tetrasperma is predominantly inbred, the species is nevertheless capable of significant heterothallic behaviour and outcrossing, and the present study shows that the spontaneous proportion of self-sterile propagules from nonmutant strains can be as high as 10% for ascospores and 20% for conidia.

TL;DR: An isolate of Botrytis cinerea produced four polygalacturonases (PGs) in a modified Czapek-Dox liquid medium containing citrus pectin, and exo-PGI and II were shown to be glycoproteins by their affinity to concanavalin A.

TL;DR: The mycoflora of serially washed healthy fine roots of Norway spruce from six climatically and edaphically different sites in Southern Bavaria was examined and mycelium radicis atrovirens α was most frequently isolated and occurred in up to 70% of roots.

TL;DR: The nuclei of two arbuscular mycorrhizal fungi, Gigaspora margarita and Glomus versiforme, were examined cytofluometrically to determine their DNA amount and look for differences in their genome size during some steps of their life cycle.

TL;DR: Canonical Variate Analysis as used to plot the relative positioning of strains in relation to the environmental variables examined found that soil pH, conductivity, temperature and altitude had minor or no effect on distribution.

TL;DR: The anamorph is raised to species rank as Aspergillus thermomutatus, and the teleomorph is described as the new species Neosartorya pseudofischeri.

TL;DR: Current knowledge of the production of organic acids by immobilized filamentous fungi is reviewed, finding immobilized systems show higher productivity than freely suspended cells and fluidized-bed reactors enable long-term operation of highly aerobic fermentations.

TL;DR: Air samples of three indoor alpine environments at different altitudes were taken by means of volumetric sampling and compared with outdoor air at the same altitude for viable fungal spores, showing significant correlation between both the indoor and outdoor environment.

TL;DR: The septal ultrastructure of nine fungal endophytes from mycorrhizas of boreal orchids was examined to corroborate identifications made previously on the basis of cultural and microscopic characteristics.

TL;DR: It is interesting to find that the genes for mating pheromones that are subject to regulation by mating type proteins in ascomycete fungi are encoded directly by matingtype genes in basidiomycetous yeasts.

TL;DR: Glomus sp.

TL;DR: The results are discussed in relation to phosphate accumulation and translocation by the extramatrical mycelium of ectomycorrhizas in soil.
