While studying the genus Amanita in Brazil, a specimen identified by J. Rick as spissa var. laeta was found. Its morphological analysis suggested that this material certainly corresponded to one used protologue of name. For reason, it is designated here neotype.

Despite conservation of the signal recognition particle (SRP) from bacteria to man, computational approaches have failed to identify SRP components from genomes of many lower eukaryotes, raising the possibility that they have been lost or altered in those lineages. We report purification and analysis of SRP in the human pathogen Cryptococcus neoformans, providing the first description of SRP in...

DNA methylation plays a crucial role in the regulation of gene expression in eukaryotes. Mushrooms belonging to the phylum Basidiomycota are highly valued for both nutritional and pharmaceutical uses. A growing number of studies have demonstrated the significance of DNA methylation in the development of plants and animals. However, our understanding of DNA methylation in mushrooms is limited. I...

The complete gene sequence and secondary structure of the mitochondrial LSU rRNA from the cultivated Basidiomycota Agrocybe aegerita was derived by chromosome walking. The A.aegerita LSU rRNA gene (13 526 nt) represents, to date, the longest described, due to the highest number of introns (eight) and the occurrence of six long nucleotidic extensions. Seven introns belong to group I, while the i...
