“…The average annual rainfall data showed quite significant differences between the subregions, exposing vineyards to different irrigation regimes (from no irrigation to 1.2 ML/ha), associated with changes in DNA methylation and gene expression. Similar findings were also reported in other grapevine cultivars, such as ‘Chambourcin’ [ 43 ] and ‘Malbec’ [ 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 ], where water deficit conditions triggered DNA hypermethylation, while in the Italian variety ‘Bosco’, miRNA regulations were detected in response to drought stress [ 59 ].…”

“…Baránková et al [ 51 ] using Merlot and Pinot Noir vines identified significant DNA methylation variability (79.9% and 70.7%, respectively), which was directly associated with the geographical location of vineyards (Czech Republic and Armenia). It is worth noting that variation in DNA methylation within the same vineyard represented only 14% (Pinot Noir group) or 16% (Merlot group) of the total level of variability recorded for each cultivar.…”

“…The main contributors to the observed variations in DNA methylation patterns were the plant age and the average annual rainfall, the latter associated with the geographical location [ 44 ]. Several other studies have also showed that the grapevine age may be associated with variations in DNA methylation, which increases with the age of the vine [ 51 , 54 , 55 , 56 , 57 ]. The average annual rainfall data showed quite significant differences between the subregions, exposing vineyards to different irrigation regimes (from no irrigation to 1.2 ML/ha), associated with changes in DNA methylation and gene expression.…”

Epigenetics refers to dynamic chemical modifications to the genome that can perpetuate gene activity without changes in the DNA sequence. Epigenetic mechanisms play important roles in growth and development. They may also drive plant adaptation to adverse environmental conditions by buffering environmental variation. Grapevine is an important perennial fruit crop cultivated worldwide, but mostly in temperate zones with hot and dry summers. The decrease in rainfall and the rise in temperature due to climate change, along with the expansion of pests and diseases, constitute serious threats to the sustainability of winegrowing. Ongoing research shows that epigenetic modifications are key regulators of important grapevine developmental processes, including berry growth and ripening. Variations in epigenetic modifications driven by genotype–environment interplay may also lead to novel phenotypes in response to environmental cues, a phenomenon called phenotypic plasticity. Here, we summarize the recent advances in the emerging field of grapevine epigenetics. We primarily highlight the impact of epigenetics to grapevine stress responses and acquisition of stress tolerance. We further discuss how epigenetics may affect winegrowing and also shape the quality of wine.

“…For the first time, the idea was presented here that it would be possible to use that epigenetic variability as a tool to track terroir of grapevines. Baránková [ 204 ] indirectly proved this hypothesis when they compared DNA methylation patterns among clones of Merlot and Pinot Noir varieties planted in completely different climatic conditions in the Czech Republic (Central Europe) and Armenia (Southern Caucasus). The DNA methylation landscapes (79.9% and 70.7% for Merlot and Pinot Noir plants, respectively) were primarily affected by the different geographical locations of the Czech and Armenian vineyards.…”

Epigenetics has emerged as an important research field for crop improvement under the on-going climatic changes. Heritable epigenetic changes can arise independently of DNA sequence alterations and have been associated with altered gene expression and transmitted phenotypic variation. By modulating plant development and physiological responses to environmental conditions, epigenetic diversity—naturally, genetically, chemically, or environmentally induced—can help optimise crop traits in an era challenged by global climate change. Beyond DNA sequence variation, the epigenetic modifications may contribute to breeding by providing useful markers and allowing the use of epigenome diversity to predict plant performance and increase final crop production. Given the difficulties in transferring the knowledge of the epigenetic mechanisms from model plants to crops, various strategies have emerged. Among those strategies are modelling frameworks dedicated to predicting epigenetically controlled-adaptive traits, the use of epigenetics for in vitro regeneration to accelerate crop breeding, and changes of specific epigenetic marks that modulate gene expression of traits of interest. The key challenge that agriculture faces in the 21st century is to increase crop production by speeding up the breeding of resilient crop species. Therefore, epigenetics provides fundamental molecular information with potential direct applications in crop enhancement, tolerance, and adaptation within the context of climate change.
