Downy mildew, caused by the oomycete Plasmopara viticola, is one of diseases causing most severe economic losses to grapevine (Vitis vinifera) production. To date, application fungicides efficient method control pathogen and implementation novel sustainable disease methods a major challenge. RNA interference (RNAi) represents biotechnological tool with great potential for controlling fungal pathogens. Recently, candidate susceptibility gene (VviLBDIf7) downy mildew has been identified in V....
Abstract Efficient grapevine downy mildew control necessitates the implementation of anti-resistance strategies to ensure ongoing efficacy available substances and optimal disease control. With gradual disappearance multi-site fungicides from market, reliance on single-site poses a long-term risk selecting strains resistant multiple modes action. Challenges in management encompass spray programs monitoring field population sensitivity. This study evaluated strategies, including two...
Oomycetes-borne diseases represent a serious problem for agriculture sustainability due to the high use of chemical products employed their control. In recent years, increasing concerns on side effects associated with fungicide utilization have led reduction permissible modes action, remaining ones continuously threatened by increase resistant strains in pathogen populations. this context, it is mandatory develop new generation fungicides characterized specificity towards target species and...
Resistance to fungicides is one of the aspects that must be considered when planning treatments achieve an optimal control grey mold, caused by Botrytis cinerea, in vineyards. In this study, extensive fungicide resistance monitoring was carried out Northern Italy (Lombardy region) evaluate several (frequency resistance, effect field treatments, mechanism and fitness) on 720 B. cinerea strains isolated from 36 vineyards.Of characterized strains, 12% were resistant a single class (3% succinate...
Downy mildew, caused by the obligate parasite Plasmopara viticola, is one of most important threats to viticulture. The exploitation resistant and susceptibility traits grapevine promising ways increase sustainability disease management. Nitrogen (N) fertilization known for influencing severity in open field, but no information available on its effect plant-pathogen interaction. A previous RNAseq study showed that several genes N metabolism are differentially regulated upon P. viticola...
ABSTRACT Fungal cell walls are dynamic extracellular matrices that enable efficient adaptation to changing environments. While the wall compositions of yeasts, human, and plant pathogenic fungi have been studied some extent, mycoparasites remain poorly characterized. Trichoderma species comprise a diverse group soil with different survival strategies lifestyles. The comparative study carbohydrate-active enzymes in 13 spp. revealed types involved chitin chitosan metabolism phylogenetically...
If you have ever kept fruits, vegetables, or even bread in your kitchen for a long time, probably noticed the formation of grayish and fuzzy covering over them. But what exactly are those grayish-white filaments? Are they dangerous us? They living things belong to group organisms called fungi. These fungi grow on other organisms, using them as source nourishment. In this article, we introduce describe how can attack plants, vegetables.
The Eurasian grapevine ( Vitis vinifera ), a species cultivated worldwide for high-quality wine production, is extremely susceptible to the agent of downy mildew, Plasmopara viticola . Nevertheless, germplasm from Georgia (Southern Caucasus, first domestication centre), characterized by high genetic variability, showed resistance traits P. cultivar Mgaloblishvili exhibited most promising phenotype in terms against Its defence response results in: i) low disease intensity; ii) sporulation;...
Durable resistance is a key objective in genetic improvement for disease grapevines, which must survive years the field presence of adaptable pathogen populations. In this study, adaptation 72 Northern Italian isolates Plasmopara viticola, downy mildew agent, has been investigated into Bianca, possessing Rpv3-1, most frequently exploited locus improvement, and Mgaloblishvili, Vitis vinifera variety newly discovered Rpv29 locus. Infection parameters (latency period, infection frequency,...
Plasmopara viticola, the oomycete causing grapevine downy mildew, is one of most important pathogens in viticulture. P. viticola a polycyclic pathogen, able to carry out numerous secondary cycles infection during single vegetative season, by producing asexual spores (zoospores) within sporangia. The extent these infections strongly influenced both quantity (density) and quality (infectivity) inoculum produced pathogen. To date, protocols for evaluating all characteristics are quite limited...
One of the major threats to viticulture is represented by fungal pathogens. Plasmopara viticola, an oomycete causinggrapevine downy mildew, one principal causes grape production losses. The most efficient management strategies are a combination agronomical practices, fungicides' applications, and use resistant varieties. Plant resistance conferred presence (R) genes. Opposed them, susceptibility (S) genes encoded plants exploited pathogens promote infection. Loss or mutation S can limit...
Abstract Botrytis cinerea , the grey mould agent, is one of most important pathogens grapevine, due to great yield losses caused and economic costs related disease control. Ground cover plants are assumed have a role in complex epidemiology pathogen, even if no information on genetic variability strains available. In this study, molecular approach, based comparative analysis nucleotide sequences multiple genes (ITS1 ‐ ITS2, G3PDH NEP1 NEP2 BC‐ hch sdh B ), was used evaluate whether ....
