520 |a Recent research has extensively covered the effects of climate change factors, such as elevated CO2, rising temperatures and water deficit, on grapevine (Vitis spp.) biology. However, the assessment of the impacts of multiple climate change-related stresses on this crop remains complex due to the large number of interactive effects among environmental factors and the regulatory mechanisms that underlie these effects. Consequently, there is a substantial discrepancy between the number of studies conducted with a single or two factors simultaneously, and those with a more holistic approach. This review focuses on how climate change factors will coexist across the viticultural areas of the globe and summarises the main interactive mechanisms affecting crop performance. We highlight how the rise in temperatures will be enhanced when dealing with specific periods, such as the ripening months. Changes in crop phenology in response to temperature have been a major focus of most studies. However, how these physiological shifts may result in deleterious effects on yield and quality deserves further research. Rising temperatures will most certainly continue to represent the most imminent threat to viticulture due to its effects on grape phenology, composition and crop water requirements. Nevertheless, elevated CO2 may offer some relief through increased water use efficiency, as recent studies have shown. Within the repertoire of regulatory mechanisms that plants possess, hormones play a major role explaining the effects of combined stresses due to their crosstalk. In fact, growth regulators fine tune stress responses depending on the multiple stresses present. The paper focuses on the multistress responses mediated by ABA and jasmonate, and on the intricate interconnections of signalling among the different plant hormones
