Traditionally, it has been believed that inheritance is driven as phenotypic variations resulting from changes in DNA sequence. However, this paradigm challenged and redefined the contemporary era of epigenetics.

Abstract Plant responses to abiotic stresses are dynamic, following the unpredictable changes of physical environmental parameters such as temperature, water and nutrients. Physiological phenotypical stress intercalated by periods recovery. An earlier can be remembered ‘stress memory’ mount a response within generation or transgenerationally. The priming’ phenomenon allows plants respond quickly more robustly stressors increase survival, therefore has significant implications for agriculture. Although evidence memory in various plant species is accumulating, understanding mechanisms implicated, especially crops agricultural interest, its infancy. Rice major food crop which susceptible causing constraints on cultivation yield globally. Advancing network will thus have impact rice sustainable production global security face climate change. Therefore, this review highlights effects priming tolerance focuses specific aspects memory, perpetuation regulation at epigenetic, transcriptional, metabolic well physiological levels. open questions future directions exciting research field also laid out.

Rice (Oryza sativa L.), an important food crop, necessitates more water to complete its life cycle than other crops. Therefore, there is a serious risk rice output due water-related stress. Drought stress results in morphological changes, including the inhibition of seed germination, reduced seeding growth, leaf area index, flag area, increased rolling, as well decrement yield traits, such plant height, biomass, number tillers, and 1000-grain yield. Stress also causes formation reactive oxygen species (ROS) O2−, H2O2, OH−, which promote oxidative plants cause damage. The process degradation owing produces cell damage reduction nutrient intake, photosynthetic rate, RWC, WUE, stomatal closure, may be responsible for transpiration rate dry matter under decreasing soil moisture. Plants have ability produce antioxidant that can either enzymatic (SOD, POD, CAT, GPX, APX) or non-enzymatic (AsA, GSH) nature overcome During drought, several biochemical osmoprotectants, like proline, polyamines, sugars, accumulated, enhance drought tolerance rice.

Drought significantly challenges global food security, necessitating a comprehensive understanding of plant molecular responses for effective mitigation strategies. Epigenetic modifications, such as DNA methylation and histone are key in regulating genes hormones essential drought response. While microRNAs (miRNAs) primarily regulate gene expression post-transcriptionally, they can also interact with epigenetic pathways potential effectors that influence chromatin remodeling. Although the role miRNAs memory is still being explored, their contribution to response requires examining these indirect effects on modifications. A aspect this exploration drought-adapted plants, offering insights into transgenerational inheritance adaptive traits. Understanding mechanisms govern maintenance erasure imprints provides nuanced how plants balance stability flexibility epigenomes. major focus dynamic interaction between hormonal pathways—such those abscisic acid (ABA), ethylene, jasmonates, salicylic (SA)—and mechanisms.
