The genetic linkage map of the medicinal mushroom Agaricus subrufescens reveals highly conserved macrosynteny with the congeneric species Agaricus bisporus
G3, 2016Co-Authors: Marie Foulongne-oriol, Cathy Spataro, Magalie Moinard, Philippe Callac, Manuela Rocha De Brito, Eustáquio Souza Dias, Delphine Cabannes, Aurélien Clement, Jean-michel SavoieAbstract:Comparative linkage mapping can rapidly facilitate the transfer of genetic information from model species to orphan species. This macrosynteny analysis approach has been extensively used in plant species, but few example are available in fungi, and even fewer in mushroom crop species. Among the latter, the Agaricus genus comprises the most cultivable or potentially cultivable species. Agaricus bisporus, the button mushroom, is the model for edible and cultivable mushrooms. We have developed the first genetic linkage map for the basidiomycete A. subrufescens, an emerging mushroom crop known for its therapeutic properties and potential medicinal applications. The map includes 202 markers distributed over 16 linkage groups (LG), and covers a total length of 1701 cM, with an average marker spacing of 8.2 cM. Using 96 homologous loci, we also demonstrated the high level of macrosynteny with the genome of A. bisporus. The 13 main LG of A. subrufescens were syntenic to the 13 A. bisporus chromosomes. A disrupted synteny was observed for the three remaining A. subrufescens LG. Electronic mapping of a collection of A. subrufescens expressed sequence tags on A. bisporus genome showed that the homologous loci were evenly spread, with the exception of a few local hot or cold spots of homology. Our results were discussed in the light of Agaricus species evolution process. The map provides a framework for future genetic or genomic studies of the medicinal mushroom A. subrufescens.

Potential of European wild strains of Agaricus subrufescens for productivity and quality on wheat straw based compost
World Journal of Microbiology and Biotechnology, 2013Co-Authors: Régulo Carlos Llarena-hernández, Nathalie Ferrer, Marie Foulongne-oriol, Michèle Largeteau, Anne Marie Farnet Da Silva, Catherine Regnault-roger, Jean-michel SavoieAbstract:The Brazilian almond mushroom is currently cultivated for its medicinal properties but cultivars are suspected all to have a common origin. The objective of this work was to assess the potential of wild isolates of Agaricus subrufescens Peck (Agaricus blazei, Agaricus brasiliensis) as a source of new traits to improve the mushroom yield and quality for developing new cultures under European growing conditions. The wild European strains analysed showed a good ability to be commercially cultivated on wheat straw and horse manure based compost: shorter time to fruiting, higher yield, similar antioxidant activities when compared to cultivars. They have a valuable potential of genetic and phenotypic diversity and proved to be interfertile with the original culture of the Brazilian almond mushroom. Intercontinental hybrids could be obtained and combine properties from both Brazilian and European germplasm for increasing the choice of strains cultivated by the mushroom growers.

Capacity for colonization and degradation of horse manure and wheat-straw-based compost by different strains of Agaricus subrufescens during the first two weeks of cultivation.
Bioresource technology, 2012Co-Authors: Anne Marie Farnet, Jean-michel Savoie, Frédérique Peter-valence, Florence Ruaudel, Leila Qasemian, Elisée FerréAbstract:Abstract The potential of Agaricus subrufescens strains to colonize and transform horse manure and wheat-straw-based mushroom compost under the physico-chemical conditions typically used for Agaricus bisporus was assessed. Lignocellulolytic activities, H 2 O 2 production and substrate transformation (assessed via CP/MAS NMR of 13 C) for certain A. subrufescens strains were similar or even greater than those obtained for an A. bisporus strain used as control. Moreover, the functional diversity of the microbial communities of the substrate was not altered by the growth of A. subrufescens after 2 weeks. These findings obtained with mesocosms simulating the incubation phase of the mushroom production process hold promise for the improvement of cultivation of this tropical Agaricus species on European standard mushroom compost.

Chemical characterization of the biomass of an edible medicinal mushroom, Agaricus subrufescens, via solid-state 13C NMR.
Journal of agricultural and food chemistry, 2011Co-Authors: Frédérique Peter-valence, Jean-michel Savoie, Carlos Llarena-hernandez, Michèle Largeteau, Florence Ruaudel, Fabio Ziarelli, Elisée Ferré, Anne Marie FarnetAbstract:The biomass of 18 strains of Agaricus subrufescens and of 13 strains of Agaricus bisporus was chemically analyzed using solid-state (13)C NMR. The study focused on polysaccharides because they can play a major role as antitumor molecules. The study also examined whether biomass chemical properties varied between the vegetative mycelium and the fruiting bodies of A. subrufescens, and these data were compared with the mycelium of A. bisporus. Qualitative differences between vegetative mycelia and fruiting bodies were observed, whereas quantitative differences were measured between the two species with a higher percentage of polysaccharides in the biomass of A. subrufescens. This Agaricus species is thus an interesting potential source of polysaccharides with medicinal properties, both from vegetative mycelium obtained in liquid cultures and from fruiting bodies produced on composts.

overview of four Agaricus subrufescens strains used in the last 15 years in brazil and other countries and current potential materials for the future
Mycological Progress, 2021Co-Authors: Diego Cunha Zied, Eustaquio Souza Dias, Wagner Goncalves Vieira, Douglas M M Soares, Cassius V Stevani, Matheus Rodrigo Iossi, Arturo PardogimenezAbstract:The mushroom Agaricus subrufescens has been synonymous with Agaricus blazei and Agaricus brasiliensis during the last decades, and there has been much discussion with regard to the origin, distribution, and nomenclature of this mushroom. Therefore, we conducted a genetic and morphological characterization of the mycelium and mushroom of four commercial strains currently cultivated in Brazil (ABL CS7, ABL 18/01, ABL 98/11, and ABL 16/01) together with an assessment of their agronomic behavior and compared these results with those published in works using other strains during the last 15 years. All the A. subrufescens strains characterized here are phylogenetically related to the Americas/Europe specimens, bearing an internal transcribed spacer region of type A (ABL 16/01) or both types A and B (ABL 18/01, ABL 98/11, and ABL CS7). We did not find any correlation between the morphological characteristics of the mycelial colonies and the agronomic behavior of the strains. Strains ABL 98/11 and ABL 16/01 produced the best yields and morphological characteristics for the mushrooms, indicating their high weight, which enhances the commercialization of the mushroom and justifies their longstanding commercial use over the last 15 years.

adaptabilidad de cepas brasilenas de Agaricus subrufescens peck a la fructificacion sobre diferentes capas de cobertura en cultivo comercial
Revista Iberoamericana De Micologia, 2014Co-Authors: Arturo Pardogimenez, Vinicius Reis De Figueiredo, Jose Emilio Pardo Gonzalez, Diego Cunha ZiedAbstract:Resumen Antecedentes Agaricus subrufescens Peck es un hongo cuyo cultivo ha despertado gran interes en todo el mundo en los ultimos anos, adquiriendo gran popularidad. Sus propiedades medicinales y culinarias hacen prever una rapida expansion del cultivo en todo el mundo. Objetivos El trabajo plantea como objetivo la evaluacion del efecto sobre los principales parametros de produccion de 3 cepas de Agaricus subrufescens que se han hecho fructificar sobre 5 capas de cobertura diferentes. Metodos Se ha llevado a cabo un ciclo de cultivo de Agaricus subrufescens en condiciones controladas en el que se han evaluado los principales parametros de produccion. Resultados Los mejores resultados han sido proporcionados por la cepa ABL 99/30. Las coberturas basadas en turba presentan mejor comportamiento que las basadas en suelo mineral. El mayor rendimiento (6,75 kg/m −2 , eficiencia biologica 27,57 kg/dt) ha sido proporcionado por la combinacion ABL 99/30-Euroveen. Conclusiones Nuestros resultados evidencian que la combinacion de la cepa ABL 99/30 utilizando una capa de cobertura basada en turba (Euroveen) ofrece un alto potencial para ser utilizada a escala comercial por el sector productor de hongos. La disponibilidad de alternativas a las especies de hongos comestibles cultivadas habitualmente puede suponer un mejor aprovechamiento de recursos y una mayor rentabilidad economica de la actividad.
