Fungicide Resistance Evolution and Detection in Plant Pathogens: Plasmopara viticola as a Case Study

Microorganisms, 2021
The use of single-site fungicides to control plant pathogens in the agroecosystem can be associated with an increased selection of resistance. The evolution of resistance represents one of the biggest challenges in disease control. In vineyards, frequent

Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1649-1661, September 2026.
The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

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

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.

Limits of Symptom‐Based Inference in Fungal Plant Disease: Latency, Quiescence and Dormancy

Plant Pathology, Volume 75, Issue 5, September‐October 2026.
Symptomless fungal infections are not biologically uniform. Latency, quiescence and dormancy represent distinct biological states with different implications for interpreting infection, symptom development and epidemic emergence. Recognising these distinctions reduces reliance on symptom‐based inference in fungal plant disease. ABSTRACT In fungal plant

Gene expression and metabolic variability in fungus‐resistant PIWI (‘Pilzwiderstandsfähig’) grape cultivars

Journal of the Science of Food and Agriculture, Volume 106, Issue 10, Page 5841-5850, 15 August 2026.
Abstract BACKGROUND Fungus‐resistant PIWI (Pilzwiderstandsfähig) grape cultivars are promising for reducing pesticide inputs in viticulture, but their enological potential is still poorly characterized. We performed a pilot, single‐vintage study integrating berry gene expression and phenolic composition in five Italian red PIWI cultivars (Cabernet ...
