Reniforma Strues, A New Yeast from Wastewater

Systematics of basidiomycetous yeasts: a comparison of large subunit D1/D2 and internal transcribed spacer rDNA regions

“…(Fig. The vegetative cells of Reniforma are unique among the yeasts; they are kidney-shaped with an elaborate skirt that circles the edge of the cell [66]. One reason is an incomplete sampling of taxa, namely the dimorphic plant parasites of the Microbotryales, sensu Bauer et al [63] for which ITS sequences are not available.…”

“…Yeast species in the Microbotryum lineage include representatives of the anamorphic genera Rhodotorula, Sporobolomyces, Reniforma and Bensingtonia. The vegetative cells of Reniforma are unique among the yeasts; they are kidney-shaped with an elaborate skirt that circles the edge of the cell [66]. R. strues appears on a long branch with Heterogastridium pycnidiodeum (teleomorph name, anamorphic name = Hyalopycnis blepharistoma), a relationship that may be arti¢cial due to long branch attraction.…”

4. F reshwater Basidiomycota

“…Yeasts, single-celled and free-floating, occur in freshwater habitats, attached to substrates or within a host (Jones and Slooff 1966;Pore and Sorenson 1990; Kurtzman and Fell 2006;Yamaguchi et al 2009;Fell et al 2011). Yeasts are poorly documented in most reviews of freshwater fungi (Goh and Hyde 1996;Shearer et al 2007;Wurzbacker et al 2010;Wurzbacker et al 2011).…”

“…Yeasts are poorly documented in most reviews of freshwater fungi (Goh and Hyde 1996;Shearer et al 2007;Wurzbacker et al 2010;Wurzbacker et al 2011). Basidiomycetous yeasts have been reported from freshwater lakes and streams, brackish water, sewagecontaminated water, glacier meltwater, and wastewater (Cooke 1976;Pore and Sorenson 1990;de García et al 2010;, and are often the dominant taxonomic group of yeasts in aquatic ecosystems (de Garcia et al 2007;Brandăo et al 2010).…”

“…Reniforma strues is an asexual species isolated from biofilms in a wastewater treatment plant (Pore and Sorenson 1990); it has a unique morphology with reniform yeast cells. The most comprehensive phylogenetic trees place R. strues in an isolated position in the Pucciniomycotina, but an apparent association with species of Cryptomycocolacomycetes and Classiculomycetes might be due to long-branch attraction (Aime et al 2006 …”
