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 morphological characteristics and stilbene production differently affect downy mildew resistance of Vitis vinifera varieties grown in Italy [PDF]

, 2014
The degree of resistance to downy mildew of grape varieties belonging to the oenological tradition of Central Italy was evaluated by the analysis of plant responses to pathogen infections carried out in natural and controlled environments.

Challenges facing the management of pesticide resistance in weeds, diseases and insect pests in European agriculture and the future of effective IPM implementation

Pest Management Science, Volume 82, Issue 4, Page 2838-2843, April 2026.
Opinion on pesticide resistance and management in the European Union (EU) and United Kingdom (UK) is presented cognisant of changes in regulation that impact on mode of action availability and cropping system choice. Abstract In recent times, pesticide resistance has been managed reasonably effectively, either proactively or reactively, by monitoring ...

Revisiting Vitis vinifera subtilase gene family: a possible role in grapevine resistance against Plasmopara viticola

Frontiers in Plant Science, 2016
Subtilisin-like proteases, also known as subtilases, are a very diverse family of serine peptidases present in many organisms. In grapevine, there are hints of the involvement of subtilases in defence mechanisms, but their role is not yet understood. The

Co-inoculated Plasmopara viticola genotypes compete for the infection of the host independently from the aggressiveness components [PDF]

, 2018
During Plasmopara viticola epidemics only few genotypes produce most of the secondary lesions and dominate in the population. Selection of dominant genotypes is hypothesized to be linked to environmental conditions and can occur rapidly, particularly if ...

When Metabolomics Meets Quantitative Genetics: An Integrative Strategy to Elucidate Plant Resistance Mechanisms

Plant, Cell &Environment, Volume 49, Issue 3, Page 1712-1727, March 2026.
ABSTRACT Gene pyramiding in crop varieties offers a promising strategy to achieve sustainable production and reduce reliance on pesticides. However, stacking resistance genes without understanding their biological functions may result in transient protection.

Phylogenomics of Plasmopara halstedii Reveals Genomic Regions Associated With the Breakdown of Sunflower Downy Mildew Resistance Genes

Molecular Ecology, Volume 35, Issue 4, February 2026.
ABSTRACT Understanding the genetic diversity and evolutionary history of plant pathogens is crucial for effective disease management strategies. Sunflower downy mildew, caused by the oomycete Plasmopara halstedii, is a worldwide threat to the sunflower oil crop.
