Plastid genomics of Vitis vinifera L. for understanding the molecular basis of  grapevine (Vitis vinifera L.) domestication

The wine sector is greatly threatened by climate change, but is also one of its contributors.

Acid aspergillopepsins-i (ap-i) have been suggested for use in winemaking due to their ability to degrade proteins, which reduces haze formation and the necessity for bentonite to achieve protein stability. These endopeptidases cleave non-terminal amino acid bonds of proteins, resulting in their degradation.

Rio grande do sul is the main grape producing state in Brazil, with the largest wine-growing area, responsible by 90% of the national production of wines and grape juices. Serra Gaúcha is the main vitivinicultural region, where around 15% of the area is destined to produce wines from vitis vinifera L. grapes. This region presents high rainfall during the grape maturation cycle, a factor that leads to great risk of attacks by fungal pathogens. the use of resistant varieties can reduce the cost and quantity of spraying, improving wine quality, focusing on a sustainable vitiviniculture.

Comprehensive evaluation of grape composition at winery receiving areas often requires multiple measurements to ensure representativeness, as well as the use of analytical techniques that are time-consuming and involve sample preparation.

A foresight study was carried out by a group of experts from INRAE, universities, INAO and FranceAgriMer from 2014 as part of the multidisciplinary “laccave” project intended to anticipate climate change in the French wine industry. The initial objective was to initiate an interdisciplinary dialogue between researchers and to feed their questions in a more systemic way. The scenario development method made it possible to build possible futures for the wine sector in the face of climate change. It began by drafting four adaptation strategies, combining different possible intensities of innovation and relocation of the vineyard.
