Fruit dropping represents a concern in many fruit species, including Vitis vinifera L. This research investigated the role of two plant growth regulators (PGRs), naphthaleneacetic acid (NAA) and 1-methylcyclopropene (1-MCP), in mitigating preharvest berry dropping (PHBD) through affecting ethylene (ET) and auxin (AUX) metabolism and interactions, k...

Abiotic stresses, such as temperature, heat waves, water limitation, solar radiation and the increase in atmospheric CO2 concentration, significantly influence the accumulation of secondary metabolites in grapevine berries at different developmental stages, and in vegetative organs. Transcriptional reprogramming, miRNAs, epigenetic marks and hormon...

Fungal pathogens involved in grapevine trunk diseases (GTDs) may infect grapevines throughout their lifetime, from nursery to vineyard, via open wounds in stems, canes or roots. In vineyards, pruning wound protection products (PWPPs) offer the best means to reduce the chance of infection by GTD fungi. However, PWPPs may affect non-target microorgan...

To understand how grapevine sinks compete with each other during water stress and subsequent rehydration, carbon (C) allocation patterns in drought‐rehydrated vines (REC) at the beginning of fruit ripening were compared with control vines maintained under drought (WS) or fully irrigated (WW). In the 30 days following rehydration, the quantity and d...

Flavescence dorée (FD) is a destructive phytoplasma disease of European grapevines. Spontaneous and cultivar-dependent recovery (REC) may occur in the field in FD-infected vines starting the year following the first symptoms. However, the biological underpinnings of this process are still largely unexplored. In this study, transcriptome sequencing...

The interest in the biological properties of grapevine polyphenols (PPs) in neuroprotection is continuously growing in the hope of finding translational applications. However, there are several concerns about the specificity of action of these molecules that appear to act non-specifically on the permeability of cellular membranes. Naturally occurri...

Tomato plants can establish symbiotic interactions with arbuscular mycorrhizal fungi (AMF) able to promote plant nutrition and prime systemic plant defenses against pathogens attack; the mechanism involved is known as mycorrhiza-induced resistance (MIR). However, studies on the effect of AMF on viral infection, still limited and not conclusive, ind...

This study investigates the impact of bunch microclimate on the evolution of some relevant carotenoids in Nebbiolo grapes. Four bunch-zone microclimates, defined by different vineyard aspect and vine vigor, were characterized by radiation and temperature indices. Berry samples were collected from green phase up to harvest, during two consecutive se...

We identified and quantified the main constitutive polyphenolic compounds of the leaves of seven Vitis species and of one interspecific cross, analysing leaf blades and veins separately, to spread light on the strategic localization of polyphenols in leaf tissues. To the best to our knowledge, the main leaf constitutive polyphenols of V. candicans,...

Abscisic acid (ABA) is the key phytohormone modeling the stomata behavior under drought conditions. However, stomata closure is not correlated with leaf ABA content in mycorrhizal olive plant. The aim of the present study is to evaluate the impact of arbuscular mycorrhizal (AM) symbiosis on the control of stomata functioning by ABA in two olive tre...

The first serious outbreak of Flavescence dorée (FD) in Piedmont (North-West Italy) dates back to 1998 in the Tortona area (Alessandria province). FD is a serious quarantine-worthy disease transmitted by the leafhopper Scaphoideus titanus Ball. Different Vitis vinifera L. biotypes react differently to the phytoplasma, in particular as to the accumu...

Despite the economic importance and the diffusion of grapevine cultivation worldwide, little is known about leaf chemical composition. We characterized the phenolic composition of Nebbiolo, Barbera, Pinot noir, Cabernet Sauvignon, Grenache and Shiraz (Vitis vinifera L.) healthy leaves (separating blades and veins) during the season. Quantitative an...

Plant virus infections are often difficult to characterize as they result from a complex molecular and physiological interplay between a pathogen and its host. In this study, the impact of the phloem‐limited grapevine virus B (GVB) on the Vitis vinifera L. wine‐red cultivar Albarossa was analyzed under field conditions. Trials were carried out over...

Grapevine has approximately 60 species; Vitis vinifera is the most known and widely cultivated specie with high productivity and specific traits in berry characteristics that have favoured the spread of viticulture in the world. American and Asian Vitis species generally present low productivity and low berry quality, but they often possess good to...

In view of climate change, the scheduling of an early harvest may be an agronomic option to limit wine alcohol, provided that a satisfactory content of secondary metabolites can be ensured in grapes. To better understand the link between grape ripening, seasonal trend and wine aroma, the aromatic expression of Barbera and Pinot Noir wines produced...
Article
The berry shrinking phenomenon in cv Shiraz (Vitis vinifera L.) is to date much debated. Currently, the critical points in Shiraz pre-harvest shrinkage are: a) the role of the xylem during post-véraison; b) the existence and timing of xylematic back flow and c) the functionality of the phloem. In order to try to resolve these issues, we traced the...

Besides signalling to soil organisms, strigolactones (SL) control above- and below-ground morphology, in particular shoot branching. Furthermore, SL interact with stress responses, possibly thanks to a cross-talk with the abscisic acid (ABA) signal. In grapevine (Vitis vinifera L.), ABA drives the accumulation of anthocyanins over the ripening seas...

Grapevine (Vitis vinifera L.) expresses different responses to water stress, depending not only on genotype, but also on the influence of vineyard growing conditions or seasonality. Our aim was to analyse the effects on drought response of two grapevine cultivars growing on two soils, one water draining (WD) containing sand 80% volume and the other...

The anthocyanin, hydroxycinnamate (HCTs) and flavonol profiles of 17 minor Vitis vinifera genotypes were studied in 2006. A wide diversity of phenolic profiles was found among varieties. HCTs and flavonols were used to discriminate white and colored berry cultivars. The possibility of using HCTs and flavonols to classify grape varieties is appealin...

Volatile composition of grapes is essential to wine quality. Wine olfactory complexity depends not only on winemaking techniques, but also on the grapevine varietal aroma that, in turn, is largely influenced by soil and climatic conditions. The aim of this work was to evaluate the influence of growing areas on the evolution of volatile compounds in...
