A re-consideration of Pseudoperonospora cubensis and P. humuli based on molecular and morphological data.
TLDR
The phylogenetic analyses of P. cubensis and P. humuli showed that they share a high level of sequence homology; the morphology of the sporangiophores, sporangia, and dehiscence apparatus confirmed the similarity of the two species, and they are reduced to the status of a taxonomic synonym.

Evolution, Diversity, and Taxonomy of the Peronosporaceae, with Focus on the Genus Peronospora.
TLDR
This review provides a wide overview of Downy mildews, ranging from macro- and micro-evolutionary patterns, their biodiversity and ecology to short overviews for the currently economically most important pathogens and potential emerging diseases.

Phylogenetic investigations in the genus Pseudoperonospora reveal overlooked species and cryptic diversity in the P. cubensis species cluster
TLDR
A cryptic species occupying a basal position within the Pseudoperonospora cubensis complex is revealed to be present on Humulus japonicus, thus providing evidence that the host jump that gave rise to Pseud operonosporiasis cubensis likely occurred from hops.

Morphological and molecular discrimination among Albugo Candida materials infecting Capsella bursa-pastoris world-wide
TLDR
The surface ornamentation of oospores of Korean specimens was morphologically distinguished from previously known characteristics of A. candida and the molecular data indicated strong support for a species partition separating Korean and other continental specimens.
Morphological and Molecular Characterization of the Causal Agent of Downy Mildew on Quinoa (Chenopodium quinoa)
TLDR
The present results indicate that the pathogen responsible for the quinoa downy mildew is identical to Peronospora variabilis and that it should not be lumped with P. farinosa as claimed previously by most studies.

The host range of Albugo candida extends from Brassicaceae through Cleomaceae to Capparaceae
TLDR
It has been demonstrated that Albugo candida has a broad host spectrum within the Brassicaceae, extending to the closely related Cleomaceae and molecular phylogenetic analysis of cox2 sequences and morphological comparison demonstrated that the host range of A. candida extends to the Capparaceae.

Towards a universal barcode of oomycetes – a comparison of the cox1 and cox2 loci
TLDR
Which out of cox1 or cox2 is best suited as a universal oomycete barcode, in terms of PCR efficiency for 31 representative genera, as well as for historic herbarium specimens, and sequence polymorphism, intra‐ and interspecific divergence is compared.
