Grapevine (Vitis vinifera L.) is susceptible to many pathogens, such as Botrytis cinerea, Plasmopara viticola, Uncinula necator, and Eutypa lata. Phytochemicals are used intensively in vineyards limit pathogen infections, but the appearance of pesticide-resistant strains a desire protect environment require that alternative strategies be found. In present study, β-1,3-glucan laminarin derived from brown algae Laminaria digitata was shown both an efficient elicitor defense responses grapevine...
A method using HPLC analysis has been used to compare the level of resveratrol and its derivatives, piceid, pterostilbene ε-viniferin, in grapevine berries three Vitis vinifera varieties. The concentration these compounds evaluated healthy Botrytis cinerea infected grape clusters, both natural vineyard conditions response UV elicitation. Keywords: Grapevines; phytoalexins; stilbenes
Summary The role of flagellin perception in the context plant beneficial bacteria still remains unclear. Here, we characterized sensing system flg22– FLAGELLIN SENSING 2 ( FLS 2) grapevine, and analyzed interaction with endophytic growth‐promoting rhizobacterium PGPR ) B urkholderia phytofirmans . functionality grapevine receptor, Vv 2, was demonstrated by complementation assays A rabidopsis thaliana fls2 mutant, which restored flg22‐induced H O production growth inhibition. Using synthetic...
Bacillus subtilis GLB191 (hereafter GLB191) is an efficient biological control agent against the biotrophic oomycete Plasmopara viticola, causal of grapevine downy mildew. In this study, we show that supernatant also highly active mildew and activity results from both direct effect pathogen stimulation plant defences (induction defence gene expression callose production). High-performance thin-layer chromatography analysis revealed presence cyclic lipopeptides fengycin surfactin in...
In order to maintain high yields while saving water and preserving non-renewable resources thus limiting the use of chemical fertilizer, it is crucial select plants with more efficient root systems. This could be achieved through an optimization both architecture uptake ability and/or improvement positive plant interactions microorganisms in rhizosphere. The development devices suitable for high-throughput phenotyping structures remains a major bottleneck. Rhizotrons growth controlled...
A purified glycoprotein from Botrytis cinerea(strain T4), identified as endopolygalacturonase 1 (T4BcPG1) by mass spectrometry analysis, has been shown to activate defense reactions in grapevine (Vitis vinifera cv. Gamay). These include calcium influx, production of active oxygen species, activation two mitogen-activated protein kinases, gene transcript accumulation, and phytoalexin production. Most these were also activated response oligogalacturonides (OGA) with a degree polymerization 9...
The phytoalexin production potential of three American Vitis species and that cultivars vinifera were evaluated in response to UV-C irradiation. Time course changes resveratrol, piceid, ε-viniferin, pterostilbene contents studied within 3 days after a short Results show the two major stilbenes accumulated as elicitation are resveratrol dehydrodimer, concentration both compounds usually reaching quantities >100 μg/g fresh weight. In contrast, piceid constantly produced low quantities. Owing...
A reversed-phase HPLC method useful for the analysis of grapevine phytoalexins resveratrol, its β-d-glucoside, ε-viniferin, and pterostilbene in leaf extracts was developed by coupling diode array detection fluorometry. Phytoalexins were extracted from UV-irradiated leaves with methanol/water (80:20) prepurified on C18 solid phase extraction cartridges. Separation achieved using a column gradient elution acetonitrile water (from 10 to 85% acetonitrile). Analyses performed injecting...
• In grapevine, the penetration and sporulation of Plasmopara viticola occur via stomata, suggesting functional relationships between guard cells pathogen. This assumption was supported by our first observation that grapevine (Vitis vinifera cv. Marselan) cuttings infected P. wilted more rapidly than healthy ones when submitted to water starvation. Here, complementary approaches measuring stomatal conductance infrared thermographic microscopic observations were used investigate...
Stilbenes, especially resveratrol and its derivatives, have become famous for their positive effects on a wide range of medical disorders, as indicated by huge number published studies. A less investigated area research is antimicrobial properties. series 13 trans-resveratrol analogues was synthesized via Wittig or Heck reactions, activity assessed two different grapevine pathogens responsible severe diseases in the vineyard. The entire series, together with resveratrol, first evaluated...

Stomata, natural pores bordered by guard cells, regulate transpiration and gas exchanges between plant leaves the atmosphere. These openings also constitute a way of penetration for microorganisms. In plants, perception potentially pathogenic microorganisms or elicitors defense reactions induces cascade events, including H(2)O(2) production, that allows activation genes, leading to reactions. Similar signaling events occur in cells response abscisic acid (ABA), stomatal closure. Moreover,...
Chitin, a major component of fungal cell walls, is well-known pathogen-associated molecular pattern (PAMP) that triggers defense responses in several mammal and plant species. Here, we show two chitooligosaccharides, chitin chitosan, act as PAMPs grapevine (Vitis vinifera) they elicit immune signalling events, gene expression resistance against diseases. To identify their cognate receptors, the family LysM receptor kinases (LysM-RKs) was annotated profiles were characterized. Phylogenetic...
