In fungi belonging to the phylum Basidiomycota, sexual compatibility is usually determined by two genetically unlinked MAT loci, one of which encodes one or more pheromone receptors (P/R) and pheromone precursors, and the other comprehends at least one pair of divergently transcribed genes encoding homeodomain (HD) transcription factors. Most species are heterothallic, meaning that sexual repro...
The crystal structure of manganese peroxidase from Phanerochaete chrysosporium at 2.06-A resolution.
The crystal structure of manganese peroxidase (MnP) from the lignin-degrading basidiomycetous fungus Phanerochaete chrysosporium has been solved using molecular replacement techniques and refined to R = 0.20 at 2.0 A. The overall structure is similar to that of two other fungal peroxidases, lignin peroxidase from P. chrysosporium and Arthromyces ramosus peroxidase. Like the other fungal peroxid...
Although viable fungi have been recovered from a wide variety of icy environments, their metabolic capabilities under frozen conditions are still largely unknown. We investigated basidiomycetous yeasts isolated from an Antarctic ice core and showed that after freezing at a relatively slow rate (0.8 degrees C min(-1)), the cells are excluded into veins of liquid at the triple junctions of ice cr...
In basidiomycetous fungi, the viability of basidiospores is an important component of sexual fitness. However, relatively little is known about the genetic and environmental factors influencing basidiospore germination. In this study, we used human opportunistic yeast pathogens, Cryptococcus neoformans and Cryptococcus deneoformans, as models to investigate the potential effects of selected gen...
Original Article Piedra hair infection is a fungal infection of the hair characterized by the presence of nodules of different hardness on the surface of hair shafts. Two types of Piedras have been found, White Piedra and Black Piedra. White Piedra caused by Basidiomycetous yeast Trichosporon spp. and Black Piedra caused by the ascomycete Piedraia hortae and Trichosporon ovoides. The low spread...
The subphylum Ustilaginomycotina comprises about 1500 species of basidiomycetous plant parasites. They are usually dimorphic, producing a saprobic haploid yeast phase and a parasitic dikaryotic hyphal phase. With only a few exceptions they occur on angiosperms and are found mainly on members of the Poaceae and Cyperaceae. Molecular methods recently have shown that anamorphic species such as mem...
Cryptococcus gattii is a basidiomycetous yeast that can be found in the environment and is one of the agents of cryptococcosis, a life-threatening disease. During its life cycle, cryptococcal cells take hold inside environmental predators such as amoebae. Despite their evolutionary distance, macrophages and amoebae share conserved similar steps of phagocytosis and microbial killing. To evaluate...
Cryptococcus neoformans is a pathogenic basidiomycetous yeast responsible for more than 600,000 deaths each year. It occurs as two serotypes (A and D) representing two varieties (i.e. grubii and neoformans, respectively). Here, we sequenced the genome and performed an RNA-Seq-based analysis of the C. neoformans var. grubii transcriptome structure. We determined the chromosomal locations, analyz...
