Biotransformation of monoterpenols upon pre‐treatment with oregano essential oil vapour alleviates downy mildew susceptibility in grapevine leaves

Plant Biology, EarlyView.
Pre‐treatment of grapevine plants with oregano essential oil vapour alleviates downy mildew susceptibility by accumulation of monoterpenol glycosides. Abstract Grapevine downy mildew, caused by the oomycete Plasmopara viticola, is a destructive disease that causes major economic losses as most elite grapevine cultivars are susceptible to this pathogen.

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 ...

The grapevine microbiota: A review on the possible impacts of plant protection programs on phyllosphere microorganisms

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
This review highlights recent advances in understanding how plant protection programs and alternative fungicides affect the taxonomic composition of the grapevine phyllosphere microbiota. Bacterial and fungal communities are primarily shaped by the plant compartment, vineyard location, and sampling time. Plant protection programs generally have a minor
