A population of Arabidopsis thaliana growing locally in a suburb of Zürich called Weiningen was observed to be infected with downy mildew. Plants were collected and the progress of infection was investigated in artificial inoculations in the laboratory. The plants proved to be highly susceptible, and pronounced intercellular mycelial growth, haustoria formation, conidiophore production, and spo...

Leaves of different Vitis vinifera L. cultivars, susceptible or resistant to downy mildew, Chasselas, Solaris, IRAC 2091 (cvs. Gamaret x Bronner) and Muscadinia rotundifolia were inoculated with Plasmopara viticola. Samples were then examined by scanning and transmission electron microscopy, by light microscopy and for their ability to synthesise stilbenes. These phytoalexins were strictly anal...

Downy mildew ( Plasmopara viticola ) and powdery Erysiphe necator are the most common economically significant fungal diseases in vineyards. The task of this work is to study genotypes new promising hybrid forms table grapes for presence resistance genes downy Rpv10 Rpv3 Ren9 using DNA-markers. was carried out on grape hybrids under working names Agat dubovskiy, Akelo, Arabella, Artek, Dubovski...

Downy mildew (DM) of cucumber (Cucumis sativus L.), caused by Pseudoperonospora cubensis, is a devastating disease of cucurbits. resistance is available but is not sufficient to eliminate the need for fungicides to control the disease. previously, the USDA plant Introduction collection of cucumber germplasm was screened in poland and North Carolina, and Ames 2354 was identified as highly resist...

The pivotal role of cultivated grapevine (Vitis vinifera L.) in many countries economy is compromised by its high susceptibility to Plasmopara viticola, the causal agent of downy mildew disease. Recent research has identified a set of genes related to resistance which may be used to track downy mildew infection. Quantification of the expression of these resistance genes requires normalizing qPC...
