Montpellier vine & wine sciences (M-WineS)

Abstract

Context and purpose of the study – The Occitanie Region is the first vine-growing area in France: 270 000 hectares of vineyard and an annual production of 15 million hectoliters. Its annual income reaches 1 900 million euros, of which 900 million euros in export.The vine and wine sector is facing many issues: inputs reduction, adaptation to climate change, maintaining the production competitiveness, digital tools integration in production and transformation processes, and the production of quality wines meeting the consumer demand.

Objectives – Montpellier Vine & Wine Sciences aims to develop the Montpellier research-educationinnovation cluster in the vine and wine sector.The goal is to bring Montpellier research and education actors all together in order to ease exchanges among research subjects: French Institute of Agronomic Research, University of Montpellier, Montpellier SupAgro, National Research Institute of Sciences and Technology for Environment and Agriculture. There is an involvement of 15 research structures in M-WineS, among them 150 scientists, 13 research labs and 2 experimental units. The M-WineS collective offers higher education and welcomes 400 students each year.The purpose of M-WineS is to better answer the vine & wine sector issues – environmental footprint reduction, adaptation to climate change, quality construction for the market, digital transition – and to strengthen the site’s visibility and attractiveness. M-WineS works with doctoral schools and community tools, and has already several links with the vine and wine sector’s stakeholders: industrial clusters, competitiveness hub, Vine and Wine cooperatives, Regional and Departmental Chambers of Agriculture, Vine inter-professions. M-WineS will also reinforce its links with international Universities.

Some representative projects

– A panel of 279 accessions of Vitis vinifera vine to develop integrated projects from gene to glass

The aim is to have a representation panel of the Vitis vinifera genetic diversity with 279 cultivars, to identify the genetic basis of the vine’s traits of interest by Genome-Wide Association Study. Exploring genetic basis and eco-physiology of the plants, linked with wine characteristics, will allow scientists to select and create grape varieties consuming less inputs, more adapted to constraining climates, and meeting the consumers demand if quality wine.

– The production competitiveness observatory

The engagement of all the concerned research structures is an indispensable asset to build an observatory of different situations, evolutions, analysis tools of the factors determining industrial competitiveness, and action-levers allowing a rising competitiveness in the short term.

This observatory will reinforce partnership with industrials and institutional stakeholders of the sector.

– A Vine & Wine Sciences researchers school

This event aims at encouraging PhD students and young scientists to learn about other fields of study. This will allow them to know more about other approaches to deal with the key issues in various fields.

– MOOC “vine&wine sciences”

The aim is implement a MOOC dedicated to introduce to vine and wine sciences with an extension of available languages, queez, videos…

EXPLORING THE INFLUENCE OF S. CEREVISIAE MANNOPROTEINS ON WINE ASTRINGENCY AND THE IMPACT OF THEIR POLYSACCHARIDE STRUCTURE

Mannoproteins (MPs) are proteoglycans from the outmost layer of yeast cell walls released into wine during alcoholic fermentation and ageing on lees processes. The use of commercial preparations of mannoproteins as additives to improve wine stability with regards to the crystallization of tartaric salts and to prevent protein haze in the case of white and rosé wines is authorized by the OIV. Regarding red wines and polyphenols, mannoproteins are described as able to improve their colloidal stability and modulate the astringent effect of condensed tannins. The latter interact with salivary proteins forming insoluble aggregates that cause a loss of lubrication in the mouth and promote a drying and puckering sensation. However, neither the interaction mechanisms involved in mannoproteins capacity to impact astringency nor the structure-function relationships related to this property are fully understood.

Influence of soil characteristics on vine growth, plant nutrient levels and juice properties: a multi-year analysis

Soil physical and chemical properties affect vine nutrition, as indicated by leaf and petiole nutrient content, in a way that may directly impact wine properties.

Light exposure is one of the major factors affecting the sensory quality of rosé wines and resulting in the light-struck fault.

New biotechnological approaches for a comprehensive characterization of AGL11 and its molecular mechanism underlying seedlessness trait in table grape

In table grapes seedlessness is a crucial breeding target, mainly results from stenospermocarpy, linked to the Thompson Seedless variety. Several studies investigated the genetic control of seedlessness identifying AGL11, a MADS-box transcription factor, as a crucial gene.
We performed a deep investigation of the whole AGL11 gene sequence in a collection of grapevine varieties revealing three different promoter-CDS combinations. By investigating the expression of the three AGL11 alleles and evaluating their ability to activate the promoter region, we show that AGL11 regulates its transcription in a specific promoter-CDS manner. By a multi-AGL11 co-expression analysis we identified a methyl jasmonate esterase, an indole-3-acetate beta-glucosyltransferase, and an isoflavone reductase as top AGL11 candidate targets. In vivo experiments further confirmed AGL11 role in regulating these genes, demonstrating its significant influence in seed development and thus in seedlessness trait.

Investigations into the effects of a commercial organic fertilizer and of quality compost on the soil and the vines

The influences of quality compost A+ and of a commercial organic fertilizer based on dry mash from bioethanol production, blackstrap molasses, vinasse, PNC (potato nitrogen concentrate) and CSL (corn steep liquor) on the humus content, on the mineral nitrogen content in the soil, in the must and in the vine leaves, on pruning wood
