Ascomycetes From North Temperate Lakes in Wisconsin
A comprehensive study of freshwater ascomycetes in seven lakes in northern Wisconsin was carried out. These lakes are part of the Long Term Ecological Research (LTER) project and have been the subject of limnological studies since the early 1900's. Our knowledge of freshwater ascomycetes is fairly …

Distribution Patterns and Taxonomy of Freshwater Ascomycetes Along the Florida Peninsula
… in the distribution patterns of freshwater ascomycetes in Florida. Results from the ordination analysis indicated that community composition is not significantly different between lentic and lotic habitats. One hundred species of freshwater ascomycetes were reported only on woody debris, 18 …

Extracellular Enzyme Production and Wood Degradation by Freshwater Lignicolous Fungi
… selected species of freshwater wood-inhabiting ascomycetes, hyphomycetes and an oomycete: (1) the range of plant components that they are able to hydrolyze; (2) whether they are able to degrade cell walls of woody tissue; (3) the extent to which they degrade specific wood components such as …

A monograph of the freshwater ascomycete family Annulatascaceae: a morphological and molecular study
… teleomorphic (sexually reproducing) freshwater ascomycetes have been referred to or included in the family Annulatascaceae. Placement in this family is based on characters that include perithecial ascomata, unitunicate cylindrical asci with relatively large J- (Melzer’s reagent negative) apical …

Hongos ectomicorrícicos de plantas leñosas en terrenos degradados de Asturias por actividad minera e industrial
… dos especies del género Scleroderma, dos Ascomycetes, pertenecientes al orden Helotiales, y hongos micorrícicos arbusculares. Se confirmo la presencia de cinco géneros de estos últimos hongos al producirse esporas en plantas trampa con rizosfera de árboles en donde se había observado su …

Succession of ectomycorrhizal fungi associated with Engelmann spruce and subalpine fir in Wyoming
… Sporocarps of higher basidiomycetes and ascomycetes were collected and identified, and ectomycorrhizal root tips sampled from each plot. Pure cultures of the basidiomycetes were routinely attempted. Mycorrhizal syntheses were subsequently attempted with both tree species using successful …

Disconnecting a Role for DNA Repair in the Pathogenicity of the Human pathogen Cryptococcus neoformans
… was also extended to two other fungal lineages, ascomycetes and zygomycetes. The second DNA repair gene, RAD23, codes for a dual function protein acting in nucleotide excision repair and as an ubiquitin receptor. Those two functions were uncoupled by creating mutant alleles and testing the …

High pressure liquid chromatography of nucleotides and nucleic acid bases from fungi
… nanogram level in four representative species of ascomycetes (P. citrinum, A. niger, F. moniliforme, and C. herbarum). Nucleotides were extracted from the mycelial mat in high yield with 10% (weight/volume) trichloroacetic acid, and then preseparated from interfering polysaccharides, …

Tor Signaling in the Fungal Kingdom
… functions for the Tor signaling cascades among ascomycetes, little is known about the pathway in basal fungal lineages, in particular among zygomycetes and chytrids. Moreover, given that the Tor pathway is the target of several small molecule inhibitors including rapamycin, a versatile …

Analysis of the sltA (stzA) gene and its orthologues in Aspergillus nidulansand other filamentous fungi
… identified are restricted to filamentous ascomycetes of the Pezizomycotina subphylum and may therefore represent specific and novel antifungal drug targets. The C-termini of StzA proteins are highly variable in both length and sequence, with no apparent conservations in amino acids or …

Characterisation of Epicoccum spp. secondary metabolism genes through de novo genome and transcriptome sequencing
… of polyketide clusters in Epicoccum and other Ascomycetes. This will lead to improved understanding of how these clusters function and are regulated in fungi and may lead to biotechnological applications and informed bioprospecting screens.

Systematics and Ecology of Truffles (Tuber)
… independently, multiple times in both the Ascomycetes and Basidiomycetes. One instance has given rise to the Tuberaceae, which is composed entirely of obligate ectomycorrhizal species. Attempts to cultivate European truffle species T. melanosporum, T. aestivum, and T. borchii are underway …

A circumscription of the earth tongue fungi class Geoglossomycetes
The earth tongue fungi are a relatively small but captivating group of fungi that have fascinated mycologists for over three hundred years. From the first mention of “Fungus ophioglossoides” in 1667 to the latest molecular genomic studies, earth tongues have often been on the cutting edge of …

APPROACHES OF MODULATION OF THERAPEUTIC TARGETS RELEVANT TO DRUG RESISTANCE
… especially a series of mold metabolites of Ascomycetes, structurally belonging to the class of azaphilones, were found to inhibit the heat shock protein Hsp90. In particular, bulgarialactone B was tested for its binding to Hsp90 using surface plasmon resonance and limited proteolysis assays …

Untersuchung der Fruchtkörperentwicklung bei dem Hyphenpilz Sordaria macrospora
Die funktionelle Analyse von Proteinen der Striatin-Familie aus Säugern gewinnt immer mehr an Bedeutung, da diese vermutlich eine zentrale Rolle in Calcium-abhängigen Signaltransduktionsprozessen einnehmen, welche vielfältige zelluläre Differenzierungsprozesse regulieren. Striatin-Proteine dienen …
