Partially purified virus preparations from sporophores of Agaricus bisporus affected with LaFrance disease had up to a 15-fold-higher RNA-dependent RNA polymerase activity than did comparable preparations from healthy sporophores. Enzyme activity was dependent upon the presence of Mg2+ and the four nucleoside triphosphates and was insensitive to actinomycin D, a-amanitin, and rifampin. The 3H-l...

The position and composition of Macrolepiota within the Agaricaceae and its phylogenetic relationships with other members of the family were investigated, using both molecular (ITS and LSU rDNA sequences) and morphological characters. The molecular data separate the genus into two clades. The first clade comprises M. procera, M. mastoidea, M. clelandii and allies and is a sister group of Leucoa...

BACKGROUND One of the main problems for the preservation of genetics resources of Agaricus subrufescens is to maintain the viability of the strains because the mycelium is very sensitive to cooling and therefore it ages rapidly. AIMS Evaluate the viability of A. subrufescens strains stored as cultures on sorghum grain (spawn) at different temperatures. METHODS Eighteen strains of A. subrufe...

The Agaricales are the largest clade of mushroom-forming fungi, in Colombia, with 544 species approximately 16,000 currently recognized worldwide phylum Basidiomycota. We document seven Agaricaceae for first time from Colombian Caribbean region. Two these newly recorded country: Leucoagaricus lilaceus Singer and roseilividus (Murrill) E. Ludw. Five reported time: Agaricus griseorimosus Pegler, ...

It has been demonstrated that the Agaricus blazei Murill (ABM) mushroom, which primarily consists of polysaccharides, possesses anti-tumor activities. However, the mechanisms by which ABM inhibits human hepatocellular carcinoma growth remain unknown. Our study demonstrates that ABM acts as an enhancer to sensitize doxorubicin (Dox)-mediated apoptotic signaling, and this sensitization can be ach...

Agaricus blazei Murrill (ABM) popularly known as 'Cogumelo do Sol' in Brazil, or 'Himematsutake' in Japan, is a mushroom native to Brazil, and widely cultivated in Japan for its medicinal uses, so it is now considered as one of the most important edible and culinary-medicinal biotechnological species. It was traditionally used to treat many common diseases like atherosclerosis, hepatitis, hyper...

Agaricus bisporus agglutinin (ABA) isolated from edible mushroom has a potent anti-proliferative effect on malignant colon cells with considerable therapeutic potential as an anti-neoplastic agent. Since previous studies on the structural requirement for binding were limited to molecular or submolecular levels of Galbeta1-3GalNAc (T; Thomsen-Friedenreich disaccharide glycotope; where Gal repres...

Agaricus blazei Murrill (ABM), a mushroom native to Brazil, is a basidiomycete brown fungus, which is popularly known as "Cogumelo do Sol" in Brazil or "Himematsutake" in Japan, and there has been a prominent increase in the use of ABM for therapeutic and medicinal purposes. ABM is useful against a variety of diseases like cancer, tumor, chronic hepatitis, diabetes, atherosclerosis, hypercholes...

The antioxidant action of ethanolic extract from Agaricus bisporus which is available in the supermarkets of Bucharest, Romania, was assessed by determining its reducing power and its radical scavenging activity. The determinations were made by analyzing the freeze-dried ethanolic extract. The radical scavenging activity was determined using 2, 2-diphenyl-1-picrylhydrazyl (DPPH), superoxide rad...
