“…Sjamsuridzal et al (1997) assumed that this strain might have been misidentified as Taphrina based on morphological, chemotaxonomic or physiological and biochemical characteristics, in addition to the sequence analysis. Since 'Taphrina' maculans CBS 427.69 is not available for distribution from the CBS, this strain has not been compared with CBS 973 T in our laboratory, but it is assumed that CBS 973 T , 'Taphrina' maculans CBS 427.69 and 'Taphrina' californica CBS 374.39 (Sjamsuridzal et al, 1997) are closely related strains.…”

Fifteen strains of the Cryptococcus laurentii complex were reclassified based on sequence analyses of 18S rDNA, the D1/D2 region of the 26S rDNA and the internal transcribed spacer regions, as well as physiological and biochemical properties. The strains were divided into phylogenetic groups I and II. The type strain of C. laurentii (CBS 139 T =ATCC 18803 T =JCM 9066 T =MUCL 30398 T =NRRL Y-2536 T ) was in phylogenetic group I. Phylogenetic group II, which was phylogenetically distant from phylogenetic group I, clustered with Cryptococcus dimennae and Bullera globispora. In phylogenetic group I, the type strain of Torula aurea (CBS 318 T =ATCC 32063 T =IFO 0372 T =NRRL Y-1582 T ) appeared to be a separate species from C. laurentii, and the designation Cryptococcus aureus comb. nov. is proposed for Torula aurea.

“…Gjaerum, 1964;Bacigálová, 1997). More recently, molecular methods (namely sequencing of the 18S rRNA gene) have been used to unveil phylogenetic relationships among Taphrina species and other members of the archiascomycetes, but this study involved only a limited number of species represented by single strains (Sjamsuridzal et al, 1997).

“…However, there has been some confusion in the literature dealing with Taphrina due to the inadvertent study of strains of ascomycetous or basidiomycetous yeasts misidentified as Taphrina species (e.g. Heath et al, 1982;Sjamsuridzal et al, 1997;Moore, 1998).…”

“…However, the validity of separating species on related hosts has been debated by several authors (Mix, 1949;Gjaerum, 1964). Molecular methods are a valuable tool for this purpose, but few studies have focused on members of the genus Taphrina (Sjamsuridzal et al, 1997;Prillinger et al, 2000). Here, we report on the re-evaluation of species differentiation within the genus based on the comparative analysis of selected genetic characteristics of strains obtained from culture collections that represent about one-third of the currently recognized species, and argue for the use of molecular methods to identify the actual Taphrina species causing infections.…”

Molecular systematics of the dimorphic ascomycete genus Taphrina

The ascomycete genus Taphrina Fries comprises nearly 100 species recognized by their mycelial states when parasitic on different vascular plants. Whereas the filamentous state is strictly phytoparasitic, the yeast state is saprobic and can be cultured on artificial media. Taphrina species are differentiated mainly on the basis of host range and geographical distribution, type and site of infection and morphology of the sexual stage in infected tissue. However, there has been little progress in the systematics of the genus in recent years, mainly because of the scarcity of molecular studies and available cultures. The main aim of the present study was the reappraisal of species boundaries in Taphrina based on the genetic characterization of cultures (yeast states) that represent about one-third of the currently recognized species. The molecular methods used were (i) PCR fingerprinting using single primers for microsatellite regions and (ii) determination of nucleotide sequences of two approx. 600 bp nuclear rDNA regions, the 59 end of the 26S rRNA gene (D1/D2 domains) and the internal transcribed spacer region (which includes the 5.8S rRNA gene). Sequencing results confirmed the monophyly of the genus (with the probable exclusion of Taphrina vestergrenii) and the combined analysis of the two methods corroborated, in most cases, separation of species defined on the basis of conventional criteria. However, genetic heterogeneity was found within some species and conspecificity was suggested for strains that have been deemed to represent distinct species. Sequences from the ITS region displayed a higher degree of divergence than those of the D1/D2 region between closely related species, but were relatively conserved within species (>99 % identity) and were thus more useful for the effective differentiation of Taphrina species. The results further allowed other topics to be addressed such as the correlation between the molecular phylogenetic clustering of certain species and the respective host plant family and the significance of molecular methods in the accurate diagnosis of the different diseases caused by Taphrina species.
