- Abstract
- Complete small ribosomal subunit RNA sequences were used to infer the relationship between several basidiomycetous yeasts, and to resolve the evolutionary position of the basidiomycetes among the fungi. The sequences were determined for Rhodosporidium toruloides (anamorph Rhodotorula glutinis), Filobasidiella neoformans (anamorph Cryptococcus neoformans), Trichosporon cutaneum, Bullera alba and Sporobolomyces roseus. The sequence of Leucosporidium scottii (anamorph formerly named Candida scottii) srRNA has already been published previously (Hendriks et al., J. Mol. Evol. 32, 167-177 (1991)). Using a tree construction program based on a distance matrix, a phylogenetic tree was constructed for all hitherto known fungal srRNA sequences, oomycetes and slime moulds not included. It showed the ascomycetes and the basidiomycetes to be sister groups, probably evolved from a zygomycete-like ancestor and diverged from each other about 840 Myr ago. Among the basidiomycetes, two clearly distinct groups can be recognized, one formed by the teliospore forming species (Rhodosporidium toruloides and Leucosporidium scottii), and the asexual yeast Sporobolomyces roseus, and the other formed by the non-teliospore forming species Filobasidiella neoformans and the asexual yeasts Bullera alba and Trichosporon cutaneum.
