Identification of Biomarkers for Defense Response to Plasmopara viticola in a Resistant Grape Variety
Downy mildew (Plasmopara viticola) is one of the most destructive diseases of the cultivated species Vitis vinifera. The use of resistant varieties, originally derived from backcrosses of North American Vitis spp., is a promising solution to reduce disease damage in the vineyards. To shed light on the type and the timing of pathogen-triggered resistance, this work aimed at discovering biomarker...
متن کاملLinking Jasmonic Acid to Grapevine Resistance against the Biotrophic Oomycete Plasmopara viticola
Plant resistance to biotrophic pathogens is classically believed to be mediated through salicylic acid (SA) signaling leading to hypersensitive response followed by the establishment of Systemic Acquired Resistance. Jasmonic acid (JA) signaling has extensively been associated to the defense against necrotrophic pathogens and insects inducing the accumulation of secondary metabolites and PR prot...
متن کاملIdentification of Lipid Markers of Plasmopara viticola Infection in Grapevine Using a Non-targeted Metabolomic Approach
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. In this work, we have used a mass spectrometry-based non-targeted metabolomic approach to identify potential Plasmopara-specific metabolites. This has led to the chara...
متن کاملVariation Within and Between Vitis spp. for Foliar Resistance to the Downy Mildew Pathogen Plasmopara viticola
Vitis vinifera grapevines are highly susceptible to downy mildew caused by the host-specific oomycete Plasmopara viticola. In humid climates like New York, where the unchecked pathogen will defoliate vines and destroy young fruit clusters, growers depend upon multiple fungicide applications for disease management. However, management of P. viticola by fungicides is tenuous, because the pathogen...
متن کاملStudying the Mechanism of Plasmopara viticola RxLR Effectors on Suppressing Plant Immunity
The RxLR effector family, produced by oomycete pathogens, may manipulate host physiological and biochemical events inside host cells. A group of putative RxLR effectors from Plasmopara viticola have been recently identified by RNA-Seq analysis in our lab. However, their roles in pathogenesis are poorly understood. In this study, we attempted to characterize 23 PvRxLR effector candidates identif...
