Hyperparasitism on Plasmopara viticola by Simplicillium lanosoniveum [PDF]

PhytoFrontiers™, 2022
A previously unknown association between Plasmopara viticola, the causal pathogen of grape downy mildew, and the mycoparasite strain F2 is described in this paper. F2 could be consistently isolated from the mildew of diseased spots on grape leaves of Kyoho ( Vitis labrusca × V. vinifera cv. Kyoho) infected with P. viticola but not from the surfaces of

Identification of Lipid Markers of Plasmopara viticola Infection in Grapevine Using a Non-targeted Metabolomic Approach [PDF]

Frontiers in Plant Science, 2018
The Oomycete Plasmopara viticola is responsible for downy mildew, which is one of the most damaging grapevine diseases. Due to the strictly biotrophic way of life of P. viticola, its metabolome is relatively poorly characterized.

Factors Affecting the Vineyard Populational Diversity of Plasmopara viticola [PDF]

The Plant Pathology Journal, 2019
Vitis vinifera is very susceptible to downy mildew (Plasmopara viticola). A number of authors have suggested different genetic populations of this fungus exist in Europe, each showing a different degree of virulence. Work performed to date indicates this diversity to be the result of different factors.

Characterization of CRN-Like Genes From Plasmopara viticola: Searching for the Most Virulent Ones

Frontiers in Microbiology, 2021
Grapevine downy mildew is an insurmountable disease that endangers grapevine production and the wine industry worldwide. The causal agent of the disease is the obligate biotrophic oomycete Plasmopara viticola, for which the pathogenic mechanism remains ...

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

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola). [PDF]

Pest Manag Sci
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Crossing Plasmopara viticola strains in controlled conditions to uncover the genomic bases of downy mildew resistance breakdown in grapevine [PDF]

BIO Web of Conferences, 2022
The biotrophic oomycete Plasmopara viticola is the causal agent of downy mildew, one of the major grapevine diseases. We report here a successful strategy to cross compatible strains of this pathogen and obtain a large viable progeny. We used this method

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.

Components of variance and heritability of resistance to important fungal diseases agents in grapevine [PDF]

Journal of Agricultural Sciences (Belgrade), 2006
In four interspecies crossing combinations of grapevine (Seedling 108 x Muscat Hamburg, Muscat Hamburg x Seedling 108, S.V.I8315 x Muscat Hamburg and Muscat Hamburg x S.V.I2375) during three years period, resistance to important fungal diseases agents ...
