Abstract
The obligate biotrophic lineages of the white blister rusts (Albuginales, Oomycota) are of ancient origin compared to the rather recently evolved downy mildews, and sophisticated mechanisms of biotrophy and a high degree of adaptation diversity are to be expected in these organisms. Speciation in the biotrophic Oomycetes is usually thought to be the consequence of host adaptation or geographic isolation. Here we report the presence of two distinct species of /Albugo/ on the model plant /Arabidopsis thaliana/, /Albugo candida/ and /Albugo laibachii/, which is formally introduced in this manuscript. Both species may occupy the same host within the same environment, but are nevertheless phylogenetically highly distinct, as inferred from analyses of both mitochondrial and nuclear DNA-sequences. Different ways of adapting to their host physiology might constitute an important factor of their different niches. Evidence for this can be gained from the completely different host range of the two pathogens. While /Albugo candida/ is a generalist species, consisting of several physiological varieties, which is able to parasitize a great variety of Brassicaceae, /Albugo laibachii/ has not been found on any host other than /Arabidopsis thaliana/. Therefore, /Albugo laibachii/ belongs to a group of highly specialized species, like the other known specialist species in /Albugo /s.str., /Albugo koreana/, /Albugo lepidii/ and /Albugo voglmayrii/. The comparative investigation of the effector genes and host targets in the generalist and the specialist species may constitute a model system for elucidating the fundamental processes involved in plant pathogen co-adaptation and speciation.
