Mgaloblishvili Rpv29 and Rpv31 loci reveal new insights on downy mildew resistance sources in Vitis vinifera

The production of certified grape planting material is one of the most important problems in the Russian federation. According to the scheme for the production of healthy grape planting material, before being introduced into in vitro culture, the source plants of each variety (Moldova, Augustin, Bart) were individually assessed for typical varietal characteristics and the presence/absence of symptoms of infection by pests.

Condensed grape tannins play a major role in the organoleptic properties and quality of red wine. Recently, a new sub-family of macrocyclic condensed tannins has been identified in red wine and named “crown tannins”. Indeed, the first compound of the family identified and characterised by NMR was the crown procyanidin tetramer which is composed of a macrocyclic structure composed of four (-)-epicatechins link together by B-type interflavanoid linkage in the following an alternative sequences of C4-C8 and C4-C6 linkage. The 3D structure of this unusual crown procyanidin family reveals a central cavity in the molecule [1].

Pest biocontrol strategies are gaining attention as eco-friendly alternatives to the use of synthetic pesticides, including in viticulture.

Las condiciones heliotérmicas en España son en general favorables a alcanzar una elevada producción de azúcares en las bayas de prácticamente todas las variedades que se cultivan en nuestro país.

What if, in 25 years, most wines were dealcoholized and flavored ? What if vines were only cultivated to combat erosion, store carbon, and provide anthocyanins…? What if climate change completely changed the list of vine varieties cultivable for wine production in France? What if food stores had completely disappeared in favor of virtual platforms? And if… because the long-term future is not predetermined and therefore not knowable, because the future is open to several possibilities, because the future does not emerge from nothing but from the present which conceals heavy trends and weak signals, prospective approaches make it possible to consider the room for maneuver that actors have to promote the advent of a future, which we can hope to be chosen, at least in part.
