ABSTRACT As in other crops, yield is an important trait to be selected for edible mushrooms, but its inheritance poorly understood. Therefore, we have investigated the complex genetic architecture of yield-related traits Agaricus bisporus through mapping quantitative loci (QTL), using second-generation hybrid progeny derived from a cross between wild strain and commercial cultivar. Yield, average weight per mushroom, number fruiting bodies m 2 , earliness, cap color were evaluated two...

Trichoderma spp., soil filamentous fungi, are antagonists that can cause great losses in mushroom production. We have investigated the influence of T. longibrachiatum on production lignocellulolytic enzymes by Pleurotus ostreatus during its vegetative growth a straw-based cultivation substrate either had been sterilized, pasteurized or not heat treated. The variations activities and electrophoretic patterns single dual cultures were used as tool for perturbation assessment. various...

Abstract BACKGROUND: Agaricus bisporus is the premier cultivated edible mushroom but usually considered to be of lesser value nutritionally and medicinally compared with other mushrooms. The objective this study was investigate radical‐scavenging properties methanolic extracts free radical‐processing enzyme activities water from A. fruit bodies. Analyses were performed on total bodies three strains separated stipe, cap gills one strain, all experimentally under same conditions. RESULTS: EC...

The almond mushroom Agaricus subrufescens (formerly blazei or brasiliensis) is cultivated at commercial level in Brazil and some Asian countries on local substrates casing mixtures. Despite its tropical origin, A. might be a seasonal option for growers western countries, where wild strains have been isolated. For this purpose, cultivation conditions were developed starting from the substrate mixture commonly used production of button bisporus France.The compost, based wheat straw horse...

Dry bubble, caused by Lecanicillium fungicola, is one of the most detrimental diseases affecting button mushroom cultivation. In a previous study, we demonstrated that breeding for resistance to this pathogen quite challenging due its quantitative inheritance. A second-generation hybrid progeny derived from an intervarietal cross between wild strain and commercial cultivar was characterized L. fungicola under artificial inoculation in three independent experiments. Analysis trait loci (QTL)...

Antagonisms between Trichoderma spp. and white-rot fungi are of interest for lignocellulose degradation mushroom cultivation. Production emergent hyphae, formation pigmented barrages production laccases were followed compared during confrontations mycelia two T. harzianum isolates with seven wood-rotting leaf litter-rotting basidiomycetes. No specific defense pattern associated each group basidiomycete was identified but the number species forming zones higher in wood decayers. induced...

Trichoderma harzianum biotype Th2, responsible for green mold disease, appeared in the North of France by end 1997. Cocultures Agaricus bisporus with four French Th2 isolates and three less aggressive species were performed conventional compost to further our understanding how establishes competes button mushroom. Spore germination was little affected A. mycelium while that other strongly inhibited. flourished uninoculated or inoculated bisporus, but mushroom is required intensive...

Abstract BACKGROUND Fumonisin B 1 ( FB ) is a mycotoxin produced by several Fusarium species and very common contaminant of maize‐based food feed throughout the world. The selection use ‐degrading microorganisms appears as promising alternative to cope with problem toxicity towards humans livestock. High moisture maize grain silage, which based on natural fermentation, could be an interesting reservoir such microorganisms. RESULTS Using in vitro simulated silage model naturally contaminated...

Trichoderma spp. is the cause of green mold, a disorder that affects cultivated mushrooms. The aims study were to establish whether improvement mushroom resistance aggressivum could be obtained by inducing reaction mechanisms before contact with pathogen and this ability was species or strain dependent. Twenty nine isolates Agaricus bisporus, 29 Lentinula edodes 18 Pleurotus studied. effect T. harzianum metabolites on mycelial growth these evaluated YMEA (yeast, malt extract agar),...
