Showing papers in "Fungal Biology in 2002"

TL;DR: In this paper, the authors investigated the role of the endophyte and its biologically active metabolites in its association with its host and found that a higher proportion of the fungal endophytes, in contrast to the soil isolates, inhibited at least one of the test organisms for antialgal and herbicidal activities.

TL;DR: There are potential applications for siderophores in medicine, reprocessing of nuclear fuel, remediation of metal-contaminated sites and the treatment of industrial waste, including enhancing pathogenicity, acting as intracellular iron storage compounds and suppressing growth of other microorganisms.

TL;DR: The results confirm the recent concept for sects Longibrachiatum and Trichoderma, indicate that the sects Hypocreanum and Pachybasium cannot be distinguished phylogenetically, and provide a first phylogenetic basis for dissection of the latter two sections.

TL;DR: A number of PCR-based methodologies have been developed for the identification of mycotoxin biosynthetic genes in different fungal genera, together with assays developed using other genes or random amplification of polymorphic DNA (RAPD) methodologies for the Identification of specific toxigenic fungi.

TL;DR: Host genotype did not effect the basic pattern of hyphal growth of Epichloe/Neotyphodium endophytes, but it strongly influenced the concentration and distribution of hyphae throughout leaves, providing support for synchronised plant and endophyte growth.

TL;DR: Each species-group contains several taxa and these taxa need to be formally described before species specific metabolite profiles can be established, according to morphological and chemical examination.

TL;DR: In several studies of oak decline in Europe, one semi-papillate Phytophthora psychrophila sp.

TL;DR: The spatial restriction of EM fungal basidiomes indicated that discrete groves of EM trees harbour an important component of regional macromycete diversity.

TL;DR: A PCR-assay based on the specific primers developed seems to be a good alternative for the deep-freeze-blotter method and plating on ARSA, especially when time is an important issue.

TL;DR: Analysis of isolates collected in Chile from grapes, tomato, kiwifruit and blueberry revealed the existence of genetic differentiation in the authors' sample between isolates from the different host plants, and PCR-RFLP markers showed that isolates sampled from grapes and tomato were genetically differentiated.

TL;DR: It is reported that wound inoculations of toxigenic endophytes of seedlings from a breeding population of white spruce were successful across a range of genotypes, and this represents the first positive evidence that the kind of mutualism between toxigenes and grasses affecting insect herbivory also may occur inwhite spruce.

TL;DR: Mapping of characters such as spore print colour, taste, and presence of acid resistant incrustations, which have been used to define infrageneric taxa in Russula, onto the phylogeny identified interesting patterns consistent with hypotheses regarding plesiomorphic and apomorphic characters.

TL;DR: The data indicate that, while the abundance of extraradical ECM fungal propagules in the upper soil profile may be reduced by prescribed burning, the effect is site-specific.

TL;DR: Results from this study demonstrate that selected salts can be used to control potato dry rot and aluminium chloride in curative application and sodium metabisulfite, sodium carbonate and sodium bicarbonate in preventive application significantly reduced the development of dry rot in potato tuber.

TL;DR: The phylogenetic position of members of the entirely asexually reproducing lichen-forming genera Lepraria and Leproloma was investigated using sequence data from the ITS1-5.8S-ITS2 and small subunit (SSU) nuclear ribosomal DNA and results indicate that most species currently referred to Leprechauns form a single monophyletic group.

TL;DR: Although the addition of KC1 to Sabouraud dextrose agar (SDAM) significantly reduced germination of the conidia of three isolates in vitro and lowered germination and appressorial development on the cuticles of Myzus persicae and Meligethes aeneus, conidia grown on SDAM and minimal medium (MM) were more aggressive than conidia derived from SDA or yeast extract agar.

TL;DR: It is concluded that the Mickevich-Farris test is more appropriate for estimating congruence and combinability between different sources of molecular data than the more widely used ILD and Templeton tests, at least when the different data sets have their respective resolution power at different depths in the phylogeny.

TL;DR: It is demonstrated that water stability of artificial soil aggregates prepared with fungal mycelia pretreated with L(-)fucose lectins were significantly reduced, indicating that fungal-derived material containing fucosyl residues plays a role in soil adhesion.

TL;DR: Hydrophobicity, appresorium formation and protease production as factors involved in early parasitism of nematode eggs are shown.

TL;DR: Differences in morphology, ITS, IGS, mtSSU and β-tubulin sequences and UP-PCR hybridization were compared between morphologically identified F. avenaceum and F. tricinctum species complex species and may be helpful in future revision in the taxonomy of these species.

TL;DR: The results obtained in the present study showed that the major pathogens associated with core rot disease of Top Red apples in South Africa belong to the A. tenuissima species-group.

TL;DR: The relationship between teleomorphs of Cordyceps spp.

TL;DR: The lichens Usnea florida and U. subfloridana have since long been recognised as distinct species, but they show many similarities in morphology, but have different reproductive strategies.

TL;DR: The level of molecular variability in the arbuscular mycorrhizal fungus (AMF) Glomus intraradices was assessed, and no evidence for genetic exchange was found on the interspecific or intergeneric level.

TL;DR: Based on the above mentioned criteria, it is confirmed that the isolates of Verticillium from B. napus in Sweden and Germany should be classified as V. longisporum.

TL;DR: These data, combined with the existence of morphological differences and somatic incompatibility between HydR1 and non-HydR1 strains, suggest that these two groups comprise distinct genetic entities.

TL;DR: Spores from R. truncatus failed to show any signs of metabolic activity and largely failed to form ectomycorrhizas on seedlings, adding to the growing body of literature demonstrating that spores of at least some species of hypogeous fungi remain viable after passage through the digestive tract of mycophagous animals.

TL;DR: It was shown that C. rosea can thrive in very different niches, and conidia germination, colonization and conidiogenesis were demonstrated in vivo in all four environments, the first report on transformation of Clonostachys rosea with marker genes.

TL;DR: Transforming ectomycorrhiza-forming basidiomycetes Suillus bovinus, Hebeloma cylindrosporum, and Paxillus involutus based on Agrobacterium tumefaciens -mediated T-DNA transfer found transformants from all three investigated species contained the GPDScP-Shble-GPDScT construct, although the fate of the foreign DNA could not be determined.

TL;DR: The results show that the Japanese isolates belong to a distinct species, Monilia polystroma sp.
