“…Contrary to the limited studies on epigenetic memory of stress and priming, there is no lack of observations of stress priming in grapevine. Some of the more recent studies that observed physiological, transcriptional, and biochemical modifications that are potentially indicative of established stress memory in grapevine include, Babajamali et al (2022), which showed that drought stress priming improved freezing tolerance in shoot and root tissues of both droughttolerant and sensitive grapevine cultivars. In addition, a study performed on dry-grown Cabernet Sauvignon suggested the more drought-resilient grapevines with superior vine water status, leaf gas exchange and berry size are likely due to long-term drought stress adaptation via stress priming (Pagay et al, 2022).…”

Climate change is expected to increase the occurrence of extreme environmental conditions. Viticulture, as agriculture in general, is highly dependent on climatic conditions, not only for yield but also for fruit quality, which is the most important factor affecting produce value at the farm-gate. This demands the development of novel plant breeding techniques that will lead to the accelerated production of more resilient grape varieties, as conventional breeding programs for perennials are often prolonged. Recent research has suggested that environmental conditions can activate a memory of stress that could result in a primed response to subsequent stress events. This is a process capable of increasing plant’s resilience to abiotic stimuli, allowing plants to better adapt to extreme environmental conditions. While the effect of priming has been observed in many plants, the underlying mechanisms are puzzling and seldom studied in perennial crops. A large body of research has been developed in the last decade linking response to stress, stress priming, and memory of stress with epigenetic mechanisms. This understanding of plant epigenetics has opened the door to the application of epigenetics to crop improvement, such as the use of epigenetic breeding for the generation of more resilient crops. Perennial crop agriculture in general, and viticulture in particular, would benefit from more in-depth knowledge on epigenetic memory of stress.

“…Nevertheless, this adaptation could be the result of the cumulative effect of adaptation induced by drought and osmopriming; however, this necessitates further investigation to elucidate these effects. Aside from annual crops, drought stress priming in grapevine was reported to improve freezing tolerance in shoot and root tissues of both drought-tolerant and -sensitive grapevine cultivars, which is indicative of established stress memory [242]. Cross-tolerance has also been recently reported for Coffea spp.…”

Plants can develop stress memory as a response to various abiotic stresses, but the underlying mechanisms are not yet fully understood. Most of the knowledge concerning the mechanisms of stress memory development and inheritance in plants is primarily based on research in the model plant Arabidopsis. While shared mechanisms exist across plant species, it is crucial to expand our understanding of epigenetic regulation in crops. Stress priming, or prior exposure to mild stress, can enhance a plant’s adaptation to future stress events and the development of stress memory. During stress priming, plants undergo physiological, biochemical, molecular, and epigenetic changes that can be transient or maintained throughout their lifespan, and in some cases, these changes can also be inherited by the offspring. In this review, we present the current state of knowledge on the development of priming-induced stress memory in agronomically important crops towards stress resilience. The most prominent abiotic stresses, namely, heat, cold, salt, drought, and waterlogging, are highlighted in relation to stress cis-/trans-priming and memory development at the intra-, inter-, and transgenerational levels. The cost for developing stress memory in plants along with the duration of these memory imprints and stress memory fading are also discussed. This review is particularly important in the era of climate change, which necessitates the development of agricultural sustainability strategies.
