Genetic relatedness among Filobasidiella species

  title={Genetic relatedness among Filobasidiella species},
  author={S. Sivakumaran and Paul D. Bridge and Peter J. Roberts},
The three accepted species of Filobasidiella, F. neoformans, F. depauperata, and F. lutea, are compared morphologically and by molecular analysis. Sequences of the internally transcribed spacer (ITS) and the small subunit (SSU) gene of the ribosomal RNA (rRNA) gene cluster were obtained, and analysed by Neighbor-joining and Maximum parsimony methods. The three species of Filobsidiella are shown to form a single monophyletic clade, rooted by Tremella mesenterica. F. lutea was recovered as a… 

Morphological and Genomic Characterization of Filobasidiella depauperata: A Homothallic Sibling Species of the Pathogenic Cryptococcus Species Complex

It is proposed that chromosomal rearrangements appear to be a major force driving speciation and sexual divergence in these closely related pathogenic and saprobic species.

Systematics of the Genus Cryptococcus and Its Type Species C. neoformans

This revision implies that if one uses a modern phylogenetic genus concept, only those anamorphic species that belong to the Filobasidiella clade should be classified as Cryptococcus species, e.g., C. neoformans, C. gattii, and C. amylolentus.

Towards an integrated phylogenetic classification of the Tremellomycetes

Cryptococcus depauperatus, a close relative of the human-pathogen C. neoformans, associated with coffee leaf rust (Hemileia vastatrix) in Cameroon.

Morphological and molecular evidence was generated supporting the identification of the fungus on rust pustules as C. depauperatus, the first record of C.depauperatu from Africa and of its association with coffee leaf rust.

Phylogeny and Phenotypic Characterization of Pathogenic Cryptococcus Species and Closely Related Saprobic Taxa in the Tremellales

This study establishes a foundation for future comparative genomic approaches that will provide insight into the structure, function, and evolution of the mating type locus, the transitions in modes of sexual reproduction, and the emergence of human pathogenic species from related or ancestral saprobic species.

Genetic and Genomic Analyses Reveal Boundaries between Species Closely Related to Cryptococcus Pathogens

This work reexamined the species boundaries of four available isolates within the C. amylolentus complex and revealed three genetically isolated species, a nonpathogenic fungal lineage closely related to the human-pathogenic Cryptococcus neoformans/Cryptococcus gattii complex.

Filobasidiella lutea: parasitism of Hypochnicium vellereum

The purpose of this paper is to confirm the connection between F lutea and its host, document variability in some morphological features, and extend the geographic range.

A new species of Filobasidiella, the sexual state of Cryptococcus neoformans B and C serotypes.

Is Penicillium monophyletic? An evaluation of phylogeny in the family Trichocomaceae from 18S, 5.8S and ITS ribosomal DNA sequence data.

Using ribosomal DNA sequences from 17 fungi, the monophylly of Penicillium and the phylogeny in the ascomycete family Trichocomaceae (= Eurotiaceae) is evaluated and the 5.8S and 5.7S motifs are determined.

Filobasidiella arachnophila sp. nov.

A new species of Filobasidiella Kwon-Chung was isolated from a dead spider and appears to be nonpathogenic and differs from previously described species in being homothallic and in lacking a yeast-like phase of growth.

Phylogeny of Discomycetes and early radiations of the apothecial Ascomycotina inferred from SSU rDNA sequence data.

A phylogenetic hypothesis recognizes Pezizales as basal and supports Nannfeldt's hypothesis (1932) of a primitive apothecial ascomata with subsequent evolution of perithecial and cleistothecial forms and a most parsimonious tree (MPT) is determined.

Phylogenetic relationships ofCryptococcus neoformans and some related basidiomycetous yeasts determined from partial large subunit rRNA sequences

The genusCryptococcus was found to be heterogeneous on the basis of partial rRNA sequences. The human-pathogenic speciesC. neoformans, comprising 4 serotypes and havingFilobasidiella neoformans andF.

A new genus, filobasidiella, the perfect state of Cryptococcus neoformans.

Differences in the manner of basidiospores formation in species of Filobasidium is not repetitious, whereas the new basidiomycete forms basidiaospores in basipetal chains by repetitious budding to warrant description of a new genus.

Phylogenetic relationships in Ganoderma inferred from the internal transcribed spacers and 25S ribosomal DNA sequences

Phylogenetic analysis of the combined data sets of the divergent domain D2 of the 25S ribosomal RNA gene and of the internal transcribed spacers indicated that sub- genus Elfvingia was monophyletic, whereas sections Characoderma and Phaeonema were not.

Diversity of the ribosomal internal transcribed spacers within and among isolates of Glomus mosseae and related mycorrhizal fungi

SUMMARY The internal transcribed spacer (ITS) region of the nuclear ribosomal RNA was amplified, cloned and sequenced from spores of five isolates of the arbuscular mycorrhizal fungus Glomus mosseae
