“…glechomae over a period of three years, whereas downy mildew on S. pratensis was easily found at different locations in Germany where S. pratensis populations were screened. This is in line with the numerous reports of downy mildew on meadow sage by other authors ( Gaponenko 1972 , Preece 2002 , Dudka et al 2004 , Brandenburger & Hagedorn 2006 , Mulenko et al 2008 , Müller & Kokes 2008 ). In contrast to the rare observations of downy mildew on ground ivy, the host plant itself is a very frequent perennial Lamiaceae , naturally distributed over large parts of Europe and west-northern Asia, and has also been introduced into North America ( Meusel 1994 ).…”

“…Apart from the sage pathogens reported so far, several other Salvia species were reported as hosts for Peronospora , such as S. lanceolata , S. pratensis , S. reflexa and S. sclarea ( Rabenhorst 1857 , Ellis & Kellerman 1887 , Gäumann 1923 , USDA 1960 , Osipjan 1967 , Kochman 1970 , Stanjavičenie 1984 ). In checklists of Peronosporaceae in Europe and the British Isles downy mildews on S. sclarea (clary sage) and S. pratensis (meadow sage), have been noted in addition to downy mildew on common sage ( Gaponenko 1972 , Dudka et al 2004 , Mulenko et al 2008 , Müller & Kokes 2008 ). The downy mildews on clary and meadow sage were usually attributed to Pe.…”

The downy mildew species parasitic to Mentheae are of particular interest, as this tribe of Lamiaceae contains a variety of important medicinal plants and culinary herbs. Over the past two decades, two pathogens, Peronospora belbahrii and Pe. salviae-officinalis have spread globally, impacting basil and common sage production, respectively. In the original circumscription of Pe. belbahrii, the downy mildew of coleus (Plectranthus scutellarioides) was ascribed to this species in the broader sense, but subtle differences in morphological and molecular phylogenetic analyses using two genes suggested that this pathogen would potentially need to be assigned to a species of its own. In the present study, Peronospora species causing downy mildew on members of the Mentheae, including clary sage (Salvia sclarea), meadow sage (S. pratensis), basil (Ocimum basilicum), ground ivy (Glechoma hederacea) and coleus (Plectranthus scutellarioides) were studied using light microscopy and molecular phylogenetic analyses based on six loci (ITS rDNA, cox1, cox2, ef1a, hsp90 and β-tubulin) to clarify the species boundaries in the Pe. belbahrii species complex. The downy mildew on Salvia pratensis is shown to be distinct from Pe. salviae-officinalis and closely related to Pe. glechomae, and is herein described as a new species, Pe. salviae-pratensis. The downy mildew on S. sclarea was found to be caused by Pe. salviae-officinalis. This is of phytopathological importance, because meadow sage thus does not play a role as inoculum source for common sage in the natural habitat of the former in Europe and Asia, while clary sage probably does. The multi-gene phylogeny revealed that the causal agent of downy mildew on coleus is distinct from Pe. belbahrii on basil, and is herein described as a new taxon, Pe. choii.

“…Sympatric co-occurrence of two congeneric downy mildew species on the same host species has rarely been recorded; additional examples include Hyaloperonospora drabae and H. norvegica on Draba nemorosa (Choi et al 2010), Plasmopara geranii-sylvatici and P. praetermissa on Geranium sylvaticum and G. palustre (Voglmayr et al 2006), Plasmopara obducens and P. constantinescui on Impatiens capensis (Voglmayr and Thines 2007), Peronospora knautiae and P. violacea on various species of Knautia and Scabiosa (Voglmayr 2003;Müller and Kokes 2008), and Peronospora alta and P. plantaginis on Plantago major (Kochman and Majewski 1970). In the distantly related white blister rusts (Albuginaceae), Choi et al (2007) and Thines et al (2009) recorded two distinct species of Albugo each from Capsella bursa-pastoris and Arabidopsis thaliana, respectively.…”

Based on morphological and molecular data, it is shown that two distinct Hyaloperonospora species parasitize Draba (syn. Erophila) verna sensu lato. Hyaloperonospora praecox is described and illustrated as a new species, and detailed descriptions and illustrations including the diagnostic disease symptoms, haustoria and oogonia are provided for H. erophilae for the first time. Based on morphological and ITS sequence data, Peronospora drabae-majusculae is synonymised with H. erophilae. Hyaloperonospora praecox differs from H. erophilae by pyriform haustoria, by non-systemic infection combined with inconspicuous infection symptoms, and by slightly larger conidia. Both species were observed on Draba verna sensu stricto and Draba boerhaviae, and do not show a host preference. Molecular and morphological evidence is presented that H. erophilae and H. praecox can co-occur in the same host population.
