A comprehensive and accurate annotation for the grapevine T2T genome 

The odors of wines are diverse, complex and dynamic and much research has been devoted to the understanding of their chemical bases. However, while the “basic” chemical part of the problem, namely the identity of the chemicals responsible for the different odor nuances, was satisfactorily solved years ago, there are some relevant questions precluding a clear understanding. These questions are related to the physicochemical interactions determining the effective volatilities of the odorants and, particularly, to the perceptual interactions between different odor molecules affecting in different ways to the final sensory outputs.

Climate change is affecting viticulture particularly because in wine production most of the value is provided by the desired tipicity. High air temperatures decouple grape sugars and anthocyanins accumulation impacting negatively wine composition. In this trial, carried out under the temperature-warm and semi-arid conditions of eastern Spain, we assessed two field strategies in cv. Bobal and Tempranillo aiming to delay ripening to cooler periods; 1) late leaf removal (LLR) and 2) late pruning (LP).

Il tema da trattare si riferisce ai vari ecosistemi viticoli mondiali, ovviamente non facilmente sintetizzabili in una relazione. Sostanzialmente si richiama

Different from wild species in arid and semiarid conditions, cultivated species are very sensitive to drought and, beyond some stress thresholds, food production is not possible

Les aires d’appellations de la Côte d’Or résultent d’une sélection humaine empirique, historique et évolutive en adéquation avec les facteurs naturels. Afin de comprendre quels facteurs naturels et humains agissent sur le caractère et l’évolution des terroirs des Côtes de Nuits et de Beaune, une méthodologie de recherche a été développée. Elle s’articule autour de deux axes, la caractérisation physique des lieux-dits viticoles et l’historicité de la qualité de ces lieux-dits. Le travail avec un S.I.G permet d’étudier l’évolution spatiale et temporelle de la qualité.
