Introduction: Genetically distinct but morphologically similar groups of Erysiphe necator Schwein. (formally Uncinula necator (Schwein.) Burrill (BRAUN and TAKAMATSU 2000) have been identified in Europe, India (DÉLYE et al. 1997) and in Australia (STUMMER et al. 2000). One group reproduces only asexually and can thus provide well-adapted persistent clones, whereas the other group can also produ...
GrapeMilDeWS is an expert-based approach for the integrated pest management (IPM) of two of the major pathogens of grapevine (Vitis vinifera): Erysiphe necator which causes powdery mildew and Plasmopara viticola which causes downy mildew. GrapeMilDeWS has been designed and tested by a team of phytopathologists. It is presented here as a formal model in Statechart. We argue that formal modelling...
Tissue colonization by grape powdery mildew (PM) pathogen Erysiphe necator (Schw.) Burr triggers a major remodeling of the transcriptome in the susceptible grapevine Vitis vinifera L. While changes in the expression of many genes bear the signature of salicylic acid (SA) mediated regulation, the breadth of PM-induced changes suggests the involvement of additional regulatory networks. To explore...
Grapevine powdery mildew (GPM), caused by the fungus Erysiphe necator, is a constant threat to worldwide production of grape berries, requiring repeated use fungicides for management. The frequent fungicide applications have resulted in resistance commonly used quinone outside inhibitor (QoI) and associated with single-nucleotide polymorphisms (SNPs) mitochondrial cytochrome b gene (cytb). In t...
Demethylation inhibitors (DMIs) have been an important tool in the management of grapevine powdery mildew caused by Erysiphe necator. Long-term, intensive use of DMIs has resulted in reduced sensitivity in field populations. To further characterize DMI resistance and understand resistance mechanisms in this pathogen, we investigated the cyp51 sequence of 24 single-spored isolates from Virginia ...
At the present stage of science development it is necessary to develop and implement grape breeding programs for immunity basing on international level knowledge about genetics pathogens that cause culture diseases. The extensive material genes resistance Plasmopara viticola Erysiphe necator ( Uncinula ), which mildew oidium diseases, has been collected thanks MAS technology. There an evidence ...
Powdery mildew ( Erysiphe necator ) is one of the most common and economically significant diseases grapes. The main method controlling disease pesticide treatment. To reduce chemical treatments, it necessary to select introduce resistant varieties into production. DNA markers are currently actively used in study grape genetic resources. Seedless highly demanded by consumers. Ren1 known mapped ...
