Life traits of four Botryosphaeriaceae species and molecular responses of different grapevine cultivars or hybrids
Life traits associated with nondestructive monitoring of gene expression involved in the defence mechanisms of five grapevine cultivars and genotypes after inoculation of wood cuttings with Botryosphaeriaceae offered useful markers for breeding or estimating the defence status of plants.
Comparison of the Impact of Two Molecules on Plant Defense and on Efficacy against Botrytis cinerea in the Vineyard: A Plant Defense Inducer (Benzothiadiazole) and a Fungicide (Pyrimethanil).
Surprisingly, the fungicide also induced the expression of defense genes and increased the polyphenol content, suggesting that BTH acts as an efficient elicitor in the vineyard and that Pyrimethanil may act, in part, as a defense-inducing agent on the vine.
Three Types of Elicitors Induce Grapevine Resistance against Downy Mildew via Common and Specific Immune Responses.
In response to a downy mildew inoculation, the leaves pre-treated with PHOS and BTH overproduced pterostilbene, and after MeJA treatment, piceids and ε-viniferin, compared to uninoculated elicitor-treated leaves, provide evidence of the different modes of action of PDS and their role in sustainable viticulture.
Impact of different elicitors on grapevine leaf metabolism monitored by 1H NMR spectroscopy
The methods applied were found to be accurate for the rapid determination and differential characterization of plant samples based on their metabolic composition and can be very useful because the application of plant defense stimulators is gaining greater importance as an alternative strategy to pesticides in the vineyard.
A Richer Community of Botryosphaeriaceae Within a Less Diverse Community of Fungal Endophytes in Grapevines than in Adjacent Forest Trees Revealed by a Mixed Metabarcoding Strategy
The hypothesis that host factors prevail on geographic effects to explain the diversity of Botryosphaeriaceae at the studied spatial scale is supported, and the features of the agroecosystem, such as management practices, were suggested to be more important than phylogeny to structure the fungal community.
Grapevine Stimulation: A Multidisciplinary Approach to Investigate the Effects of Biostimulants and a Plant Defense Stimulator.
The proposed approach investigated the effects of three phytostimulants on Vitis vinifera and revealed differences in the modulation of genes involved in defense and primary metabolism and some genes were identified as potential markers of their action.
