“…Albugo candida is possibly restricted to the three closely related families, Brassicaceae, Capparaceae, and Cleomaceae ), while it seems not to reach out to the more distant family Resedaceae. This is in line with the evidence that genera and species of the Albuginaceae are tending to host clade-limited radiation (Thines and Voglmayr 2009), suggesting that either the metabolism of the hosts or the presence of specific effector targets limits the host range of A. candida. However, considering that only a few specimens of the rare species A. resedae could be included in this study and given the fact that in several cases two species of Albugo were previously recorded on the same host genus or even the same host species (Choi et al 2007(Choi et al , 2008 Fig.…”

“…Rao was confirmed as a distinct species (Choi et al 2007). As the considerable diversity in Albugo parasitic to Brassicaceae had previously been overlooked, it is likely that more than a dozen additional species await their discovery on Brassicaceae (Thines and Voglmayr 2009). In contrast to the vast majority of obligate parasites of the Oomycota, the exceptional broad host range of A. candida has been ascertained in molecular phylogenetic analyses, confirming that it extends from Brassicaceae to Cleomaceae and Capparaceae Juss.…”

“…Schröt., Oomycota) consists of obligate plant parasitic oomycetes causing white blister rust disease in economically important agricultural crops and common weeds belonging to the order Brassicales Bromhead. About 50 species were originally described in this genus (Biga 1955;Choi and Priest 1995;Thines and Voglmayr 2009) before molecular phylogenetic studies demonstrated that this genus contains several phylogenetically highly distinct lineages (Riethmüller et al 2002;Hudspeth et al 2003;Voglmayr and Riethmüller 2006). This led to the segregation of two genera, Pustula Thines, parasitic to asterids and Wilsoniana Thines, containing parasites of Caryophyllales Perleb (Thines and Spring 2005).…”

The genus Albugo s.str. causes white blister rust on four families of the Brassicales, Brassicaceae, Capparaceae, Cleomaceae, and Resedaceae. Recent phylogenetic studies have revealed that several host specific lineages are present within Albugo on Brassicales, while it was also confirmed that Albugo candida has an exceptionally wide host range which extends from Brassicaceae to Cleomaceae and Capparaceae. The Albugo species infecting the Resedaceae was attributed in monographic studies as well as local floras to either A. resedae or, applying a broader species concept, to A. candida. In the present study, A. resedae specimens were morphologically and molecularly compared to the five Albugo species so far confirmed from Brassicales, A. candida, A. koreana, A. laibachii, A. lepidii, and A. voglmayrii. Both morphological differences of oospore ornamentation and phylogenetic analysis of cox2 mtDNA sequences provided evidence that A. resedae is distinct from A. candida and from the additional four species so far described from Brassicaceae. It thus seems possible that so far unknown factors restrict Albugo candida to Brassicaceae and its sister families, Cleomaceae and Capparaceae.

“…Albugo centaurii is grouped with both described and undescribed species of Pustula, and also exhibits the equatorial wall thickenings typical for that genus (Thines & Spring 2005;Thines & Voglmayr 2009). Therefore, this species is transferred to the genus Pustula.…”

“…The genus Pustula is one of the three genera of white blister rust (WBR), which in addition includes Albugo and Wilsoniana (Thines & Spring 2005;Thines & Voglmayr 2009), and are characterised by the production of rust-like sori (pustules) on all aerial parts of their host plants. The hosts of the WBR are primarily in eudicotyledonous plants, especially the asterids (Asteranae), Caryophyllales and rosids (Rosanae) (sensu APG III, 2009).…”

The phylogeny and taxonomy of the mastigonate ‘fungal‐like’ organisms (stramenopiles) are described. The marine Labyrinthulomycota occur in the same stramenopile clade as the bioecids and opalinids, whilst the hyphochytrids and biflagellate oomycetes occur in a sister clade, together with the ochrophyte algae. The uniflagellate hyphochytrids are a small group whose closest relative appears to be the phagotrophic flagellate Pirsonia . The largest and best documented of the straminipile fungi are the oomycetes. There are a number of early diverging oomycete clades (Classes incertae sedis) consisting of mostly holocarpic marine species that are parasites of algae and invertebrates. The more advanced, largely freshwater and terrestrial fungal‐like oomycetes, fall into two main classes, the Saprolegniomycetes and Peronosporomycetes. The former largely encompasses the saprotrophic water moulds, whilst the latter contains the majority of the economically important plant pathogens, including the white blister rusts (Albuginales), Pythium, Phytophthora and the downy mildews (Peronosporales). Key Concepts Molecular phylogenetics reveals most bioflagellate fungal‐like organisms traditionally studied by mycologists and occur in the stramenopile (heterokont) clade within the SAR (formerly chromalveolate) superkingdom. These fungal‐like organisms have probably evolved from a photosynthetic flagellate ancestor and there have been several independent plastid loss events. The traditional taxonomy of all of these organisms has had to be substantially re‐evaluated in the light of recent molecular studies.
