“…This yeast-type is characteristic for Ustilago species of dicotyledonous plants, which were transferred recently in the genus Microbotryum (16,81). A dominance of mannose, presence of galactose, commonly occurrence of fucose, and the absence of xylose in purified yeast cell walls are indicative for the Microbotryum type.…”

The presence or absence of fucose, galactose, rhamnose, and xylose as well as the ratio of glucose to mannose after hydrolysis of purified yeast cell walls are valuable characters to assign yeasts or yeast states of Ascomycetes and Basidiomycetes phylogenetically. The coupling of pellicular anion-exchange resins (Dionex CarboPac PA-1) with pulsed amperometric detection provides a simple, quick, selective, and sensitive method for the analysis of yeast cell wall carbohydrates. Phragmobasidial smut fungi of monocotyledonous (Ustilago s. str., Sporisorium) and dicotyledonous (Microbotryum, Sphacelotheca) host plants cluster in two different, phylogenetically distinct yeast types, the Microbotryum type and the Ustilago type. In contrast, all smut fungi with simple holobasidia (Entyloma, Melanotaenium) from monocots and dicots investigated so far, exhibit a cell wall carbohydrate spectrum characteristic for the Ustilago type. Ustilentyloma fluitans, although a phragmobasidial smut fungus on grasses, whose smut spores and parasitic symptoms resemble Entyloma species, display the neutral sugar pattern of the Microbotryum type. The close phylogenetic relationship between the Graphiolales, Ustilaginales s. str. (phragmobasidial smuts of monocots), and Exobasidiales was

“…(= Ustilago violacea [Pers.] Fuckel) (Ustilaginaceae) (Deml & Oberwinkler, 1982) is a heterobasidiomycete that is obligatorily parasitic on susceptible members of the Caryophyllaceae, which it sterilizes to complete its life cycle (Baker, 1947). The fungus utilizes the anthers of its host to produce purple‐brownish, diploid teliospores.…”

We investigated genetic diversity in West European populations of the fungal pathogen Microbotryum violaceum in sympatric, parapatric and allopatric populations of the host species Silene latifolia and S. dioica, using four polymorphic microsatellite loci. In allopatric host populations, the fungus was highly differentiated by host species, exhibiting high values of FST and RST, and revealed clear and distinct host races. In sympatric and parapatric populations we found significant population differentiation as well, except for one sympatric population in which the two host species grew truly intermingled. The mean number of alleles per locus for isolates from each of the host species was significantly higher in sympatric/parapatric than in allopatric populations. This suggests that either gene flow between host races in sympatry, or in case of less neutral loci, selection in a more heterogeneous host environment can increase the level of genetic variation in each of the demes. The observed pattern of host‐related genetic differentiation among these geographically spread populations suggest a long‐term divergence between these host races. In sympatric host populations, both host races presumably come in secondary contact, and host‐specific alleles are exchanged depending on the amount of fungal gene flow.

“…The integration of molecular phylogenetic analyses, host plant taxonomy, and in several cases morphology appeared to be a useful combination of tools to break this impasse. Consequently, the caryophyllaceous anther smuts were split and currently include 20 species that are mostly highly host-specific (Deml & Oberwinkler 1982;Scholz & Scholz 1988;V anky 1988;Chlebicki & Sukov a 2005;Lutz et al 2005Lutz et al , 2008Denchev 2007a, b;Denchev et al 2009). Thereby the number of described species is probably only a small fraction of the actual number of caryophyllaceous anther smuts worldwide, as can be estimated from the magnitude of host species listed in the literature (Zundel 1953;Thrall et al 1993;V anky 1994;Antonovics et al 2003;Hood et al 2010;Savchenko & Heluta 2010).…”
