Volatile linalool activates grapevine resistance against downy mildew with changes in the leaf metabolome

Current Plant Biology, 2023
Volatile organic compounds (VOCs) are produced by plants in response to biotic and abiotic stimuli. In grapevine, volatile terpenoids are triggered by downy mildew infection (caused by Plasmopara viticola), suggesting their involvement in plant defense ...

Suppressive Activity of Glechoma hederacea Extracts against the Phytopathogenic Oomycete Plasmopara viticola, and First Screening of the Active Metabolites

Agriculture, 2023
Plasmopara viticola is a destructive oomycete that affects grapevines, causing significant economic losses worldwide. This study highlights how the plant Glechoma hederacea might be at the basis for the development of biofungicides to control P. viticola.

New insights from short and long reads sequencing to explore cytochrome b variants in Plasmopara viticola populations collected from vineyards and related to resistance to complex III inhibitors.

PLoS ONE, 2023
Downy mildew is caused by Plasmopara viticola, an obligate oomycete plant pathogen, a devasting disease of grapevine. To protect plants from the disease, complex III inhibitors are among the fungicides widely used.

FORECASTING MODEL BASED ON CUMULATIVE DEGREE DAYS FOR INCUBATION PERIOD OF Plasmopara viticola (Berk. & M.A. Curtis) Berl. & De Toni

Journal of Agriculture and Plant Sciences, 2022
The overall development of Plasmopara viticola and its occurrence in time and space cause rapid disease increases. The incubation period is only part of the life cycle of P. viticola between infection and the first appearance of symptoms.

Distribution and host range of the grapevine plasmodiophorid Sorosphaera viticola [PDF]

, 2015
Sorosphaera viticola, an obligate parasite of grapevine, was first detected in 2003 in roots of Vitis berlandieri x V. riparia rootstocks in a vineyard in the German Rheingau. To estimate the distribution and the abundance of S.

The Climate-Driven Genetic Diversity Has a Higher Impact on the Population Structure of Plasmopara viticola Than the Production System or QoI Fungicide Sensitivity in Subtropical Brazil

Frontiers in Microbiology, 2020
Downy mildew, caused by Plasmopara viticola, is the main disease affecting vineyards in subtropical Brazil. Here, we collected 94 P. viticola isolates from four organic and conventional vineyards in the two main grape-growing states of Brazil to evaluate

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

Simple Techniques for Long-Term Storage of Plasmopara viticola

Phytopathologia Mediterranea, 2006
Propagules of Plasmopara viticola or fragments of P. viticola infected host tissue were stored by three techniques, freezing at –25°C, dehydration with CaCl2, and freeze-drying.
