“…The ESI‐MS detection was performed in negative ion mode or positive mode with the following optimised parameters: capillary temperature 400°C, capillary voltage −3 V, nebuliser gas flow 1.75 L min −1 , desolvation gas flow 1 L min −1 , and spray voltage 5 kV. Analysis were performed in negative mode for benzoic acids, hydroxycinnamic acid derivatives, flavonols and flavan‐3‐ols, positive mode for anthocyanins . The quantification of each compound identified was performed on each raisin sample collected.…”

27 phenolic compounds from four phenolic families (i.e. flavan-3-ols, phenolic acids, flavonols and anthocyanins) have been characterised in the raisins of three white and two red grapes. The total phenolic and anthocyanins content vary widely among different raisins. Strong correlations between antioxidative capacity and phenolic content and between antioxidative capacity and flavonol content were noticed.

“…From the plant side, more details have been unveiled, especially with regard to the plant physiological and molecular responses occurring in various organs. For instance, sensory attributes of musts and wine from esca symptomatic plants reveal a significant decrease in the product quality: biochemical analysis on berries display a decreased accumulation of catechins and anthocyanins coupled with an increase of minerals and acids content (Calzarano et al, 2008(Calzarano et al, , 2018Lorrain et al, 2012). In addition, diseased plants display an impaired water transport (caused by xylem dysfunction), which in turn leads to a considerable decline of leaf gas exchange and water use efficiency traits (Edwards et al, 2007;Pouzoulet et al, 2014).…”

Summary Europe is the world largest grape producer, but in recent years, the report of diseases due to infection by grapevine trunk pathogens (GTPs) is becoming one of the main constraints for viticulture. Among grapevine trunk diseases (GTDs), esca syndrome is one of the most complex, characterized by simultaneous infection of several fungi, which leads to important reduction in yield and quality. Previous characterization of fungal isolates associated with esca syndrome leads to the recognition of at least three important players: Phaeocremonium minimum, Phaemoniella chlamydospora and Fomitiporia mediterranea. Here we isolated and characterized molecularly fungal endophytes directly from field wood tissues of plants showing or not esca symptoms. In addition, to better characterize such collection, a deep RNA sequencing (100 M reads in paired‐end) to screen for mycovirus presence was performed. Thirty‐nine viral genomes were detected, 38 of which were putative new viral species; some of these viruses infected GTPs, including P. minimum and F. mediterranea. In this work, we reported for the first time a curated collection of grapevine fungal endophytes identifying the associated mycoviruses some of which could be employed in future biotechnological exploitation as biological control agents for sustainable plant protection.

Background and Aims:The impact of grey mould (Botrytis cinerea (B. cinerea)) was quantified on chemical, phenolic and sensory qualities of grapes, derived musts and wines. Methods and Results: Analyses were carried out by using naturally or artificially infected grape berries at ripeness or overripeness. In grape seeds, chemical analyses revealed no major differences between healthy and rotten grapes. In grape skins of Botrytis-affected berries, concentrations of all the phenolic compounds (anthocyanins and proanthocyanidin monomers, dimers and trimer) decreased drastically. Mean degree of polymerization of the proanthocyanidin polymeric fraction was also affected in skins. Chemical analyses of musts and wines made with different percentages of rotten berries showed a moderate impact of the pathogen on their phenolic composition. Nevertheless, sensory analyses underlined a loss of wine sensory quality perceptible from a threshold as low as 5% of Botrytis-affected grapes onwards. Conclusion: Phenolic variations and the associated negative impact in grapes, derived musts and wines may be related to oxidation phenomena from B. cinerea. The main effects of severity/age of grey mould and the level of berry maturity are also discussed. Significance of the Study: B. cinerea drastically affects the phenolic and organoleptic properties of grape skins and derived wines. Therefore, prophylactic actions early in the vineyard, evaluation of the sanitary status of the harvested grapes and berry sorting are primordial even under low disease pressure.
