چکیده

We describe a modified Agrobacterium-mediated method for the efficient transformation of Agaricus bisporus. Salient features of this procedure include cocultivation of Agrobacterium and fruiting body gill tissue and use of a vector with a homologous promoter. This method offers new prospects for the genetic manipulation of this commercially important mushroom species.

Agrobacterium tumefaciens mediated transformation of Agaricus bisporus

Agrobacterium tumefaciens is known to transfer parts of its tumor-inducing plasmid to filamentous fungi including Agaricus bisporus. We have used this transformation system to transform germinating basidiospores of A. bisporus. Analysis of hygromycin B-resistant clones showed that the T-DNA integrated at random sites and in multiple copies into the host genome. Furthermore we have been able to ...

Establishing molecular tools for genetic manipulation of the pleuromutilin-producing fungus Clitopilus passeckerianus.

We describe efficient polyethylene glycol (PEG)-mediated and Agrobacterium-mediated transformation systems for a pharmaceutically important basidiomycete fungus, Clitopilus passeckerianus, which produces pleuromutilin, a diterpene antibiotic. Three dominant selectable marker systems based on hygromycin, phleomycin, and carboxin selection were used to study the feasibility of PEG-mediated transf...

Characterization of serine proteinase expression in Agaricus bisporus and Coprinopsis cinerea by using green fluorescent protein and the A. bisporus SPR1 promoter.

The Agaricus bisporus serine proteinase 1 (SPR1) appears to be significant in both mycelial nutrition and senescence of the fruiting body. We report on the construction of an SPR promoter::green fluorescent protein (GFP) fusion cassette, pGreen_hph1_SPR_GFP, for the investigation of temporal and developmental expression of SPR1 in homobasidiomycetes and to determine how expression is linked to ...

An abundant hydrophobin (ABH1) forms hydrophobic rodlet layers in Agaricus bisporus fruiting bodies.

The SDS-insoluble protein fraction of Agaricus bisporus fruiting bodies was solubilized with trifluoroacetic acid. On SDS-PAGE this fraction was found to contain one abundant protein with an apparent M(r) of 16 kDa. The N-terminal amino acid sequence of this protein was determined and RT-PCR used to isolate a cDNA clone which upon sequencing identified the protein as a typical class I hydrophob...

Search for Proteins in the Liquid Extract of Edible Mushroom, Agaricus bisporus, and Studying their Antibacterial Effects

The edible mushrooms (basidomycetes) have high nutritional value, promote the immune system, and as a source of natural antimicrobial substances have been used to cure bacterial infections since ancient times.Various kinds of proteins with several biological activities are produced by mushrooms. In this research, in order to evaluate antibacterial activity of edible mushrooms, we isolated prote...
