As global climate change intensifies, the occurrence and severity of various abiotic stresses will significantly threaten plant health productivity. Drought stress (DS) is a formidable obstacle, disrupting normal functions through specific morphological, physiological, biochemical, molecular mechanisms. Understanding how plants navigate DS paramount to mitigating its adverse effects. In response DS, synthesize or accumulate growth regulators (PGRs), including phytohormones, neurotransmitters, gasotransmitters, polyamines, which present promising sustainable green chemical strategies adapt tolerate conditions. These PGRs orchestrate crucial structure function adjustments, activating defense systems modulating cellular-level responses, transcript levels, transcription factors, metabolic genes, stress-responsive candidate proteins. However, efficacy these molecules in depends on species, applied PGR dose, treatment type, duration exposure, stages. Thus, exploring integrated impact enhancing fitness tolerance for food security agriculture. This review investigates responses explains potential exogenously diverse PGRs, dissects complex chemistry among sheds light omics approaches harnessing basis tolerance. updated delivers comprehensive mechanistic insights leveraging enhance overall under

Abstract Plants, as sessile organisms, must adapt to a range of abiotic stresses, including drought, salinity, heat, and cold, which are increasingly exacerbated by climate change. These stresses significantly impact crop productivity, posing challenges for sustainable agriculture food security. Recent advances in omics studies genetics have shed light on molecular mechanisms underlying plant stress responses, the role calcium (Ca 2 ⁺) signaling, liquid–liquid phase separation (LLPS), cell wall-associated sensors detecting responding environmental changes. However, gaps remain understanding how rapid signaling is integrated with slower, adaptive processes. Emerging evidence also highlights crosstalk between immunity, growth regulation, mediated key components such RAF-SnRK2 kinase cascades, DELLA proteins, etc. Strategies enhance resistance without compromising yield include introducing beneficial alleles, spatiotemporal optimization decoupling from inhibition. This review emphasizes importance interdisciplinary approaches innovative technologies bridge fundamental research practical agricultural applications, aiming develop resilient crops production an era escalating challenges.

ABSTRACT Production of high‐yield and high‐quality fruits is always the long‐term objective fruit crop cultivation, which, however, challenged by various abiotic stresses such as drought, extreme temperatures high salinity, adverse impacts on crops are exacerbated climate change in recent years. To cope with these environmental stressors, have evolved adaptative strategies involving physiological changes molecular regulation. In this review, we summarise relevent photosynthesis, osmotic reactive oxygen species (ROS) equilibrium, metabolism protein homeostasis response to stresses. Moreover, perception stimuli well progress underlying regulatory mechanisms also discussed. Based our current knowledge, possible for stress resilience improvement accordingly proposed. addition, discuss challenges identification key nodes plant responses multiple development stress‐resilient crops, addressing issues future would advance understanding how combat facilitate breeding superior that can adapt thrive changing environments.
