1. Association of genes from different sources of resistance to major cacao diseases
ABSTRACT This study aimed to select genotypes resistant to witches’ broom (WB) and black pod (BP), major cacao diseases in Brazil, as well as incorporate resistance genes to moniliasis supplemented by clones EET75 and UF273, forming populations of second-cycle recurrent selection. Moniliophthora perniciosa (2 × 105 basidiospores/mL) was inoculated on 30-d

3. Psathyrella atlantica (Agaricales: Basidiomycota), a new species from Brazil
ABSTRACT Psathyrella atlantica is described based on material collected in an Atlantic Forest fragment in the state of Pernambuco, Northeast Brazil. It is characterized by slender, whitish and caespitose basidiomata; pileus with orange, small and floccose-squamulose veil remnants; presence of a persistent but fragile-membranous annulus; basidiospores 5-7 ×

4. Genome-wide gene expression patterns in dikaryon of the basidiomycete fungus Pleurotus ostreatus
Abstract Dikarya is a subkingdom of fungi that includes Ascomycota and Basidiomycota. The gene expression patterns of dikaryon are poorly understood. In this study, we bred a dikaryon DK13 × 3 by mating monokaryons MK13 and MK3, which were from the basidiospores of Pleurotus ostreatus TD300. Using RNA-Seq, we obtained the transcriptomes of the three strains

5. Taxonomic studies of Amanita muscaria (L.) Lam (Amanitaceae, Agaricomycetes) and its infraspecific taxa in Brazil
We analyzed specimens identified as Amanita muscaria, some recently collected and others already deposited in herbaria, in Brazil. We concluded that two subspecies of A. muscaria occur in Brazil: A. muscaria var. muscaria; and A.muscaria var. flavivolvata. The first taxon was found in association with Castanea sativa, and the second (one specimen only) was f

6. Presença e características de RNAs mensageiros nos basidiósporos de Pisolithus microcarpus / Presence and characteristics of messanger RNA in the basidiospores of Pisolithus microcarpus
As baixas percentagens de germinação dos basidiósporos do fungo ectomicorrízico Pisolithus microcarpus dificultam a obtenção de estirpes monocarióticas, material para estudos de genética quantitativa da associação micorrízica, inviabilizam a utilização de esporos em experimentos de mutagênese visando à identificação de genes importantes para

7. Basidiosporogênese em Agaricus brasiliensis / Basidiosporogenesis in Agaricus brasiliensis
O cogumelo Agaricus brasiliensis S. Wasser et al. é um fungo nativo do Brasil que apresenta grande perspectiva de utilização e consumo devido às suas propriedades nutricionais e medicinais, entretanto, estudos sobre a biologia básica da espécie são escassos. Este trabalho teve por objetivo estudar o processo de basidiosporogênese e a variação do n�

8. Identificação e caracterização de proteinas expressas no espaço intercelular de folhas de Theobroma cacao na interação com Moniliophthora perniciosa / Identification and characterization of proteins expressed in the intercellular space of leves from Theobroma cacao infected by Moniliophthora perniciosa
The invasion of the plant apoplast is a critical phase of the infection for numerous pathogens, including the fungus M. perniciosa (Mp) that remains in the intercellular space at the parasitic stage until about 60 days. Thus, the understanding of plant defenses induced in the apoplasm and the response mechanisms that the pathogens used for bypassing these de

9. Light microscopy of basidia, basidiospores, and nuclei in spores and hyphae of Filobasidiella neoformans (Cryptococcus neoformans).
Three hypha-forming strains of Cryptococcus neoformans were induced to form basidia and basidiospores. Light microscopy showed that basidia formed at the ends of terminal hyphal cells and were able to produce from a few to many basidiospores. The morphology of the sexual structures indicated that these strains belonged to the recently described perfect state

10. Mating System and Basidiospore Formation in the Lignin-Degrading Basidiomycete Phanerochaete chrysosporium
Prototrophic strains recovered from crosses between auxotrophic strains of the lignin-degrading basidiomycete Phanerochaete chrysosporium were induced to fruit. The progeny of most of these self-crosses were prototrophic, indicating that the nuclei of the original prototroph were wild-type recombinants rather than complementary heterokaryons and that the bin

11. Alternative methods for production and staining of Phanerochaete chrysosporium basidiospores.
Homokaryotic isolates of Phanerochaete chrysosporium are generally obtained by stimulating the production of basidiospores. The most commonly used method requires a special incubator that is maintained at 28 degrees C with continuous illumination. Here we report an alternate method which permits the production of basidiopores with common laboratory incubator

12. Induction of Dimorphism in the Basidiomycete Lenzites saepiaria1
Sugars can serve as the germinant for basidiospores of the wood-rotting fungus Lenzites saepiaria. Hexoses sterilized by autoclaving were better germinants than hexoses that were sterilized by filtration. The degradation products in heated hexose which were responsible for the stimulation of germination were levulinic and formic acid. Another product of hexo
