“…The relative contributions of these two mechanism are not always clear and an in-depth discussion of these factors is outside the scope of the current review (see the review by Flexas et al , 2004 ). In grape, the photosynthetic machinery appears to be very tolerant to mild, and even medium, levels of water deficit ( Flexas et al , 1998 ; Chaves et al , 2010 ; Dayer et al , 2019 ). For example, Flexas et al (2002) demonstrated that g s needed to be reduced by 60–70% before changes in electron transport rate and non-photochemical quenching of chlorophyll fluorescence were observed.…”

Water availability is arguably the most important environmental factor limiting crop growth and productivity. Erratic precipitation patterns and increased temperatures resulting from climate change will likely make drought events more frequent in many regions, increasing the demand on freshwater resources and creating major challenges for agriculture. Addressing these challenges through increased irrigation is not always a sustainable solution so there is a growing need to identify and/or breed drought-tolerant crop varieties in order to maintain sustainability in the context of climate change. Grapevine (Vitis vinifera), a major fruit crop of economic importance, has emerged as a model perennial fruit crop for the study of drought tolerance. This review synthesizes the most recent results on grapevine drought responses, the impact of water deficit on fruit yield and composition, and the identification of drought-tolerant varieties. Given the existing gaps in our knowledge of the mechanisms underlying grapevine drought responses, we aim to answer the following question: how can we move towards a more integrative definition of grapevine drought tolerance?

“…Nonetheless, in this context of low photochemical efficiency, in which high light and high temperature conditions can often exacerbate the damage of water deficit, the dissipation of nonradiative energy through the light-harvesting complexes (LHC) of PSII may represent the most effective protection mechanism against high solar radiation levels, temperature and drought (Palliotti et al, 2009, Villalobos-González et al, 2022. In addition, the activation of the xanthophyll cycle is paramount under these conditions, promoting photoprotection by improving the thermal dissipation of energy (non-photochemical quenching), preventing the production of reactive oxygen species, and increasing the thylakoid membrane tolerance to lipid peroxidation (Demmig-Adams and Adams, 2006, Dayer et al, 2019).…”

The exposure of viticulture to climate change and extreme weather conditions makes the winemaking sector particularly vulnerable, being one of its major challenges in the current century. While grapevine is considered a highly tolerant crop to several abiotic stresses, Mediterranean areas are frequently affected by adverse environmental factors, namely water scarcity, heat and high irradiance, and are especially vulnerable to climate change. Due to the high socio-economic value of this sector in Europe, the study of adaptation strategies to mitigate the negative climate change impacts are of main importance for its sustainability and competitiveness. Adaptation strategies include all the set of actions and processes that can be performed in response to climate change. It is crucial to improve agronomic strategies to offset the loss of productivity and likely changes in production and fruit quality. It is important to look for new insights concerning response mechanisms to these stresses to advance with more effective and precise measures. These measures should be adjusted to local terroirs and regional climate change projections for the sustainable development of the winemaking sector. This review describes the direct climate change impacts (on phenology, physiology, yield and berry quality), risks, and uncertainties for Mediterranean viticulture, as well as a set of canopy, soil and water management practices that winegrowers can use to adapt their vines to warmer and drier conditions.

“…The entity of this phenomenon was different according to the cultivar, suggesting that less anisohydric cultivars are more sensible to ABA [ 73 ]. Despite these evidences, our knowledge on this topic is still scarce, especially on grapevine [ 75 ]. Future research is still needed, in order to better understand the complex relations occurring between ABA and hydraulic regulation, which occurs with a high intraspecific variability.…”

The foreseen increase in evaporative demand and reduction in rainfall occurrence are expected to stress the abiotic constrains of drought and salt concentration in soil. The intensification of abiotic stresses coupled with the progressive depletion in water pools is a major concern especially in viticulture, as most vineyards rely on water provided by rainfall. Because its economical relevance and its use as a model species for the study of abiotic stress effect on perennial plants, a significant amount of literature has focused on Vitis vinifera, assessing the physiological mechanisms occurring under stress. Despite the complexity of the stress-resistance strategy of grapevine, the ensemble of phenomena involved seems to be regulated by the key hormone abscisic acid (ABA). This review aims at summarizing our knowledge on the role of ABA in mediating mechanisms whereby grapevine copes with abiotic stresses and to highlight aspects that deserve more attention in future research.
