Ethephon Elicits Protection Against Erysiphe necator in Grapevine
Journal of Agricultural and Food Chemistry, 2008The grapevine (Vitis vinifera) is susceptible to many pathogens such as Botrytis cinerea, Plasmopara viticola, Erysiphe necator, and Eutypa lata. Phytochemicals are used extensively in vineyards to reduce pathogen infections, but the appearance of pesticide-resistant pathogen strains and the need for environmental protection require the use of ...

Genetic variation and survival of Erysiphe necator in tropical India
Tropical Plant Pathology, 2019The heterothallic, biotrophic fungus Erysiphe necator causes powdery mildew on grapes which impacts the yield and quality of fruits and their processed products. Two genetic groups, A and B, have been described which overwinter either as flag shoots or chasmothecia.

Ascospore maturation and discharge in Erysiphe necator
2008Ascospores of Erysiphe necator are a relevant source of inoculum for spring infections. They form within chasmothecia (formerly named cleistothecia) which develop on the affected grapevine tissue in late summer to autumn, disperse to the bark by rain-splashes, and overwinter.

Detection of a Specific Transposon in Erysiphe necator from Grapevines in France
Journal of Phytopathology, 2007AbstractThe biotrophic fungus, Erysiphe necator the causal agent of the grape powdery mildew, has two genetic groups A and B in European and Australian vineyards. A strain of group A was used to isolate a DNA sequence that exhibits high sequence homology to RNaseH of a non‐LTR (long tandem repeat) retrotransposon of Glomerella cingulata.

Le popolazioni di Erysiphe necator
2015Capitolo 4 in sintesi • Gli studi genetici sulle popolazioni di E. necator hanno ricevuto un grande impulso a partire dalla metà degli anni ‘90; • Diversi studi hanno portato alla definizione di una “teoria dei biotipi”, che inizialmente distingueva un genotipo “I” (corrispondente a un biotipo germogli a bandiera) e di un genotipo “III ...

Journal of Agricultural and Food Chemistry, 2006
Grapevine is subject to a number of diseases that affect yield and wine quality. To limit the excessive use of phytochemicals in the vineyard, alternative strategies have to be developed. Plant treatment with signaling molecules like elicitors stimulates their natural defense mechanisms.
