    <p>Some are common targets of research on asthma (<i>Alternaria alternata</i>), while many are not (<i>Laccaria laccata</i>, <i>Epicoccum nigrum</i>). A drawing of a very small “dust” seed (<i>Orchis masculata</i>) is provided for comparison. A = ascospore, B = basidiospore, M = mitospore. Figure adapted from <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1003371#ppat.1003371-Ingold1" target="_blank">[30]</a>.</p

    Experimental demonstration of the loss of cellulolytic saprotrophic capabilities by ectomycorrhizal <i>Amanita</i> species.

    <p>Fourteen species, including saprotrophic and ectomycorrhizal <i>Amanita</i> and two saprotrophic <i>Volvariella</i> species, were grown on sterile grass litter to test for the use of litter as a sole carbon source. Enzyme activities of endoglucanase (E), cellobiohydrolase (C) and beta-glucosidase (ß) were also measured. The same species were grown on media with a protein (casein hydrolysate) as sole nitrogen source. Colony diameter as well as clearing of milk agar was measured to indicate growth on protein and protease activity, respectively. Values of cellulolytic and proteolytic growth and activity are expressed as relative to the maximum value (from 0 to 1) for each parameter across the species. The difference in growth between ectomycorrhizal and saprotrophic species on litter is highly significant, according to phylogenetically independent contrasts (F<sub>1,11</sub> = 7.84, <i>p</i> = 0.017). Contrasts for all other data were not significant.</p

    Mating Types of Strains

    No full text
    This file contains the mating type information for all the Neurospora crassa strains used to test the SPREAD algorithm. The column labelled "FGSC" lists the Fungal Genetics Stock Center strain IDs and the column labelled "mat" lists the mating type. "AA" = mating type "A", "a" = mating type "a"
