mycelial growth and substrate acidification of ectomycorrhizal fungi in response to different minerals.a colorimetric method was developed to permit semi-quantitative measurement of substrate acidification by different ectomycorrhizal and one saprotrophic fungus growing on media containing one of five different minerals. overall, substrate acidification differed between fungal species and the degree of variation in acidification in response to different minerals was highly species-dependent. mycena galopus and cortinarius glaucopus produced the least biomass of all tested species and produced the ...200419712344
enzyme production by mycena galopus mycelium in artificial media and in picea sitchensis f1 horizon needle litter.mycena galopus is among the most important leaf litter decomposers in uk coniferous and angiosperm woodlands, having the potential to utilise all the major constituents of plant litter. even so, the enzyme or combination of enzymes produced by m. galopus responsible for lignin depolymerisation was previously unknown. a range of media from liquid and semi-solid cultures to more natural substrata was tested to determine whether laccase was produced by an isolate of m. galopus, m9053. malt extract ...200314531622
the molecular basis for the natural resistance of the cytochrome bc1 complex from strobilurin-producing basidiomycetes to center qp inhibitors.mitochondria from the strobilurin a producing basidiomycetes strobilurus tenacellus and mycena galopoda exhibit natural resistance to (e)-beta-methoxyacrylate inhibitors of the ubiquinol oxidation center(center qp) of the cytochrome bc1 complex. isolated cytochrome bc1 complex from s. tenacellus was found to be highly similar to that of saccharomyces cerevisiae with respect to subunit composition, as well as spectral characteristics and midpoint potentials of the heme centers. to understand the ...19968631367
cytochrome b gene structure and consequences for resistance to qo inhibitor fungicides in plant pathogens.the cytochrome b (cyt b) gene structure was characterized for different agronomically important plant pathogens, such as puccinia recondita f sp tritici (erikss) co johnston, p graminis f sp tritici erikss and hennings, p striiformis f sp tritici erikss, p coronata f sp avenae p syd & syd, p hordei gh otth, p recondita f sp secalis roberge, p sorghi schwein, p horiana henn, uromyces appendiculatus (pers) unger, phakopsora pachyrhizi syd & p syd, hemileia vastatrix berk & broome, alternaria solan ...200616688790
characterization of laboratory mutants of venturia inaequalis resistant to the strobilurin-related fungicide kresoxim-methyl.several agricultural fungicides related to the antifungal strobilurins act as inhibitors of respiration by binding to mitochondrial cytochrome b. two types of laboratory mutants resisting higher doses of the strobilurin-related inhibitor kresoxim-methyl were characterized for venturia inaequalis, the causal agent of apple scab. selection of mutagenized conidia by kresoxim-methyl yielded mutants altered in the expression of alternative respiration during the stage of conidia germination. cytochro ...200011057448
