Phased grapevine genome sequence of an Rpv12 carrier for biotechnological exploration of resistance to Plasmopara viticola

Frontiers in Plant Science, 2023
The downy mildew disease caused by the oomycete Plasmopara viticola is a serious threat for grapevine and can cause enormous yield losses in viticulture. The quantitative trait locus Rpv12, mediating resistance against P.

Molecular characterization of cellulose synthase (CesA) genes and impact of mutations on fungicide resistance in oomycetes [PDF]

, 2012
Many oomycetes are important pathogens of plants (e.g. arable crops, fruit and forest trees), animals or microbes and, upon attacking their hosts, cause considerable economic damage mainly in agriculture and aquaculture.

Effects of mechanical pre-bloom defoliation on cordon de Royat pruned Sangiovese (Vitis vinifera L.) vines

OENO One, 2011
Aims: Recent trials on Sangiovese vines have shown that hand defoliation of shoot basal leaves at pre-bloom is effective in reducing fruit set and yield, leading to better grape composition and quality.

High night temperature promotes downy mildew in grapevine via attenuating plant defence response and enhancing early Plasmopara viticola infection

Plant Protection Science, 2021
The night temperature is one of the critical environmental factors affecting the grape berry quality. The objective of this study was to clarify whether a high night temperature promotes downy mildew on grapevines.

Leaf Microbiome Data for European Cultivated Grapevine (Vitis vinifera) During Downy Mildew (Plasmopara viticola) Epidemics in Three Wine-Producing Regions in France

PhytoFrontiers, 2023
Grapevine downy mildew (Plasmopara viticola) is a major disease of European cultivated grapevine (Vitis vinifera L.) against which a large amount of synthetic pesticides are used. Developing microbial biocontrol of P.

The management of Phomopsis viticola in Tarnave vineyards [PDF]

Romanian Journal of Horticulture, 2022
Phomopsis viticola, in poorly managed vineyards, can produce a lot of damage due to its year-to-year infection pattern. In combination with a high spore reserve from the previous year, this causes reduced grape yields.

Grapevine leaf MALDI-MS imaging reveals the localisation of a putatively identified sucrose metabolite associated to Plasmopara viticola development

Frontiers in Plant Science, 2022
Despite well-established pathways and metabolites involved in grapevine-Plasmopara viticola interaction, information on the molecules involved in the first moments of pathogen contact with the leaf surface and their specific location is still missing. To

The Durability of Quantitative Host Resistance and Variability in Pathogen Virulence in the Interaction Between European Grapevine Cultivars and Plasmopara viticola

Frontiers in Agronomy, 2021
European grapevine, Vitis vinifera, carries no major resistances against Plasmopara viticola, the causal agent of grapevine downy mildew. The introgression of quantitative trait loci conferring resistance to P.
