Climate change has exacerbated the rate and intensity of abiotic stresses such as drought and salinity, posing significant threats to the crop growth and yield. This review comprehensively explores recent physiochemical and molecular approaches to abiotic stress tolerance in plants. It highlights the complex physiological adjustments, including stomatal regulation, osmotic balance, and altered growth patterns, that plants undergo in response to environmental stressors. The review delves into the biochemical pathways involved in stress response, notably the glyoxalase system and ascorbate-glutathione pathway, emphasizing their roles in maintaining cellular homeostasis and detoxifying reactive oxygen species. A significant portion of the review is dedicated to elucidating the molecular mechanisms underlying plant stress tolerance, focusing on the modulation of gene expression, regulation of stress-responsive genes, and the potential of genetic engineering to enhance resilience. We also discuss the contribution of secondary metabolites and both enzymatic and non-enzymatic antioxidants in mitigating the adverse effects of stress. Moreover, the review addresses the advancements in technological tools that have revolutionized our understanding of stress physiology, including genomic editing and transcriptomic analyses. The comprehensive synthesis of current research findings provides valuable insights into the development of innovative strategies to enhance plant tolerance to abiotic stress, contributing significantly to the field of sustainable agriculture and global food security in the era of climate change.
