  • phylloplane yeasts from portugal seven novel anamorphic species in the tremellales lineage of the Hymenomycetes basidiomycota producing orange coloured colonies
    Fems Yeast Research, 2005
    Co-Authors: Joao Inacio, Laura Portugal, Isabel Spencermartins, Álvaro Fonseca
    Abstract:

    A survey of epiphytic yeasts on leaves of selected Mediterranean plant species collected at the ‘Arrabida Natural Park’ (Portugal) yielded about 850 isolates, mostly of basidiomycetous affinity. Amongst the basidiomycetes, 35 strains showed the following characteristics: production of orange-coloured colonies, ability to produce starch-like compounds, assimilation of d-glucuronic acid and/or inositol, inability to utilize nitrate, and formation of ballistoconidia by many of the isolates. This group of yeasts was assigned to the Tremellales lineage of the Hymenomycetes and was further characterised using a combination of conventional phenotypic identification tests with molecular methods, namely PCR fingerprinting and rDNA sequencing. Eight additional strains presumptively identified as Bullera armeniaca, B. crocea or Cryptococcus hungaricus were also studied. Twenty-eight strains could be assigned to or were phylogenetically related to recognised species of Dioszegia in the ‘Luteolus clade’, but the 15 remaining strains belonged to other clades within the Tremellales. Ten phylloplane isolates were identified as Dioszegia hungarica, one as D. aurantiaca, another as D. crocea and three others were ascribed to the recently described species D. zsoltii. Seven novel species, viz. Cryptococcus amylolyticus, C. armeniacus, C. cistialbidi, Dioszegia buhagiarii, D. catarinonii, D. fristingensis and D. takashimae, are proposed for the remaining strains that did not correspond to any of the hitherto recognised species.

  • systematics of basidiomycetous yeasts a comparison of large subunit d1 d2 and internal transcribed spacer rdna regions
    Fems Yeast Research, 2002
    Co-Authors: Gloria Scorzetti, Jack W Fell, Álvaro Fonseca, Adele Statzelltallman
    Abstract:

    Basidiomycetous yeasts in the Urediniomycetes and Hymenomycetes were examined by sequence analysis in two ribosomal DNA regions: the D1/D2 variable domains at the 5' end of the large subunit rRNA gene (D1/D2) and the internal transcribed spacers (ITS) 1 and 2. Four major lineages were recognized in each class: Microbotryum, Sporidiobolus, Erythrobasidium and Agaricostilbum in the Urediniomycetes; Tremellales, Trichosporonales, Filobasidiales and Cystofilobasidiales in the Hymenomycetes. Bootstrap support for many of the clades within those lineages is weak; however, phylogenetic analysis provides a focal point for in-depth study of biological relationships. Combined sequence analysis of the D1/D2 and ITS regions is recommended for species identification, while species definition requires classical biological information such as life cycles and phenotypic characterization.

  • biodiversity and systematics of basidiomycetous yeasts as determined by large subunit rdna d1 d2 domain sequence analysis
    International Journal of Systematic and Evolutionary Microbiology, 2000
    Co-Authors: Jack W Fell, Gloria Scorzetti, Teun Boekhout, Álvaro Fonseca, Adele Statzelltallman
    Abstract:

    The molecular systematics of 337 strains of basidiomycetous yeasts and yeast-like fungi, representing 230 species in 18 anamorphic and 24 teleomorphic genera, was determined by sequence analysis of the D1/D2 region of the large-subunit rDNA. The data were compared with published sequences of other basidiomycetous fungi. The results demonstrated that the yeast species and genera are phylogenetically distributed among the Microbotryum, Sporidiobolus, Agaricostilbum and Erythrobasidium clades of the Urediniomycetes; the Tremellales, Trichosporonales ord. nov., Filobasidiales and Cystofilobasidiales clades of the Hymenomycetes; and the Ustilaginales, Microstromatales and Malasseziales clades of the Ustilaginomycetes. Genera such as Bensingtonia, Cryptococcus, Rhodotorula and Sporobolomyces are polyphyletic, i.e. they occur in two or more clades. In contrast, other genera, e.g. Bullera, Cystofilobasidium, Fellomyces, Filobasidiella, Filobasidium, Kondoa, Kurtzmanomyces, Leucosporidium, Rhodosporidium, Sporidiobolus and Udeniomyces, are monophyletic. The majority of the species can be identified using D1/D2 analyses, although the internal transcribed spacer region is required to distinguish closely related species. The intergenic spacer region is recommended for additional differentiation of species and strains.
