Abiotic stress memory in plants provides the potential to circumvent some of the damaging effects of different stresses. Different abiotic stressors can trigger various physiological changes in the plant, including alterations to growth and development, that may adopt distinct epigenetic signatures depending on the underlying stress cue and plant species. Epigenetic changes, such as reversible modifications in DNA and histones, can regulate the expression of stress-related genes, thereby enabling drought or salinity memory. In this review, we focus on epigenomic changes induced by various stresses in various plant species and stress modalities, emphasizing the crucial roles of epigenic regulatory mechanisms in both stress-memory recall and transgenerational stress memory, as summarized in this paper.
