Brain abscess caused by Schizophyllum commune: an emerging basidiomycete pathogen.
Despite the worldwide distribution and prevalence of Schizophyllum commune, an emerging basidiomycetous pathogen, human infections occur only rarely. We describe the first well-documented pulmonary infection caused by S. commune which disseminated to the brain of a 58-year-old patient undergoing empiric corticosteroid therapy. Magnetic resonance imaging scans revealed ring-enhancing masses. His...
متن کاملIdentification of Indole-3-Acetic Acid in the Basidiomycete Schizophyllum commune.
Indole-3-acetic acid (IAA) was detected in the ether extracts of culture filtrates of indigotin-producing strains of the basidiomycete Schizophyllum commune. Several solvents, known to give distinctly different R(F) values for IAA, and 3 location reagents gave identical results with synthetic IAA and IAA found in the extract. Confirmation was obtained by the Avena straight growth test, split pe...
متن کاملTranscriptome and functional analysis of mating in the basidiomycete Schizophyllum commune.
In this study, we undertook a functional characterization and transcriptome analysis that enabled a comprehensive study of the mating type loci of the mushroom Schizophyllum commune. Induced expression of both the bar2 receptor and the bap2(2) pheromone gene within 6 to 12 h after mates' contact was demonstrated by quantitative real-time PCR. Similar temporal expression patterns were confirmed ...
متن کاملSomatic recombination in Schizophyllum commune.
A CONSIDERABLE effort has been put forth in the past few years to elucidate the mechanisms of internuclear genetic exchange in vegetative mycelia in the fungi (PONTECORVO 1956; RAPER 1959; DAY 1960a). PONTECORVO (1956) described a system whereby, following the formation of a heterokaryon and a diploid nucleus, the phenomenon of crossing-over was a process distinct from that of haploidization. C...
متن کاملDikaryons of the basidiomycete fungus Schizophyllum commune: evolution in long-term culture.
The impact of ploidy on adaptation is a central issue in evolutionary biology. While many eukaryotic organisms exist as diploids, with two sets of gametic genomes residing in the same nucleus, most basidiomycete fungi exist as dikaryons in which the two genomes exist in separate nuclei that are physically paired and that divide in a coordinated manner during hyphal extension. To determine if ha...
