Methyl jasmonate/ethephon cotreatment synergistically induces stilbene production in "Vitis vinifera" cell suspensions but fails to trigger resistance to "Erysiphe necator"

OENO One, 2009
Aim: The aim of the present investigation was to determine whether methyl jasmonate and ethylene could synergistically induce grapevine foliar cuttings (Vitis vinifera) defense mechanisms and enhance resistance to Erysiphe necator.

Formation of Erysiphe necator Chasmothecia in the Pacific Northwest United States [PDF]

Plant Disease, 2019
In the Pacific Northwest, chasmothecia formation is not observed in vineyards until the beginning of véraison despite heavy infestations whereby 100% of leaf tissue is covered by Erysiphe necator. Mating type proximity and distribution were sampled from individual lesions (∼71 mm2) on leaf tissue in a stratified sampling from three canopy heights at ...

Surface wax in the ancestral grapevine Vitis sylvestris correlate with partial resistance to Powdery Mildew

BMC Plant Biology, 2023
Background Powdery Mildew of Grapevine belongs to the major diseases in viticulture and requires intensive use of fungicides. Genetic introgression of resistance factors from wild grapes from North America and, recently, China, has been successful, but ...

Use of beneficial bacteria and their secondary metabolites to control grapevine pathogen diseases [PDF]

, 2013
Grapevine is one of the most important economic crops yielding berries, wine products as well as derivates. However, due to the large array of pathogens inducing diseases on this plant, considerable amounts of pesticides—with possible negative impact on

Study of the portuguese populations of powdery mildew fungus from diverse grapevine cultivars (Vitis vinifera)

OENO One, 2015
Aims: The main goal of this work was to describe the genetic diversity and population structure of Portuguese isolates from Erysiphe necator using a new approach for the sampling of DNA from this pathogen.

Induction of a Grapevine Germin-Like Protein (VvGLP3) Gene Is Closely Linked to the Site of Erysiphe necator Infection: A Possible Role in Defense?

Molecular Plant-Microbe Interactions, 2007
Germin-like proteins (GLP) have various proposed roles in plant development and defense. Seven novel GLP cDNA clones were isolated from grapevine (Vitis vinifera cv. Chardonnay).

Potential and actual ascospore release of Erysiphe necator chasmothecia in Austria [PDF]

Journal of Plant Diseases and Protection, 2020
AbstractAscospores of grape powdery mildew (Erysiphe necator Schw.) play a crucial role in the disease onset in spring in many vine-growing areas. We investigated the physiological maturation of chasmothecia and the time of the first potential ascospore release in three grape-growing areas in Austria by providing standardized conditions for ascospore ...

Strobilurin (QoI) Resistance in Populations of Erysiphe necator on Grapes in Michigan [PDF]

Plant Disease, 2012
Powdery mildew, caused by Erysiphe necator, is the most common and destructive disease of grapes (Vitis spp.) worldwide. In Michigan, it is primarily controlled with fungicides, including strobilurins (quinone outside inhibitors [QoIs]). Within the United States, resistance to this class of fungicides has been reported in E.

The grapevine (Vitis vinifera) LysM receptor kinases VvLYK1-1 and VvLYK1-2 mediate chitooligosaccharide-triggered immunity [PDF]

, 2018
Chitin, a major component of fungal cell walls, is a well-known pathogen-associated molecular pattern (PAMP) that triggers defense responses in several mammal and plant species.
