Host Jumps and Radiation, Not Co‐Divergence Drives Diversification of Obligate Pathogens. A Case Study in Downy Mildews and Asteraceae
Even though the microevolution of plant hosts and pathogens has been intensely studied, knowledge regarding macro-evolutionary patterns is limited. Having the highest species diversity andExpand

Phylogenetic investigations in the genus Pseudoperonospora reveal overlooked species and cryptic diversity in the P. cubensis species cluster
Pseudoperonospora cubensis is one of the most devastating diseases of cucurbitaceous crops. The pathogen has a worldwide distribution and occurs in all major cucurbit growing areas. It had beenExpand

Towards a universal barcode of oomycetes – a comparison of the cox1 and cox2 loci
Oomycetes are a diverse group of eukaryotes in terrestrial, limnic and marine habitats worldwide and include several devastating plant pathogens, for example Phytophthora infestans (potato lateExpand

Evolution, Diversity, and Taxonomy of the Peronosporaceae, with Focus on the Genus Peronospora.
Downy mildews are a notorious group of oomycete plant pathogens, causing high economic losses in various crops and ornamentals. The most species-rich genus of oomycetes is the genus Peronospora. ThisExpand

The host range of Albugo candida extends from Brassicaceae through Cleomaceae to Capparaceae
Capers (Capparis spinosa) are affected by white blister rust attributed to Albugo capparidis or, applying a broad species concept, to Albugo candida. Within the past 3 years, a great diversity withinExpand

The molecular phylogeny of the white blister rust genus Pustula reveals a case of underestimated biodiversity with several undescribed species on ornamentals and crop plants.
Despite their economic importance, the knowledge of the biodiversity of many plant pathogens is still fragmentary. In this study we show that this is true also for the white blister rust genusExpand

Phylogenomics of Bartheletia paradoxa reveals its basal position in Agaricomycotina and that the early evolutionary history of basidiomycetes was rapid and probably not strictly bifurcating
The higher level phylogeny of fungi has been addressed in previous studies, but for those analyses, either taxon sampling or gene sampling was low, or some basal lineages important for the inferenceExpand

Multi-locus tree and species tree approaches toward resolving a complex clade of downy mildews (Straminipila, Oomycota), including pathogens of beet and spinach.
Accurate species determination of plant pathogens is a prerequisite for their control and quarantine, and further for assessing their potential threat to crops. The family PeronosporaceaeExpand

Evolution of diversity in Albugo is driven by high host specificity and multiple speciation events on closely related Brassicaceae.
The Albuginaceae, responsible for white blister rust disease on various angiosperms, are obligate biotrophic oomycetes that are only distantly related to downy mildews (Peronosporaceae). TheirExpand

Morphological and molecular confirmation of Albugo resedae (Albuginales; Oomycota) as a distinct species from A. candida
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 severalExpand
