Climate change exacerbates biotic and abiotic stress in plants, which significantly undermine crop development, agricultural productivity, and also food security on a global scale. Primary abiotic stresses like drought, salinity, extreme temperature fluctuations, heavy metal toxicity, and nutrient imbalances contribute to considerable yield reductions and pose a risk to the sustainability of agriculture systems. Projections indicate that the occurrence and amount of these stressors are estimated to increase, necessitating the advancement of innovative strategies for breeding stress-resilient crops. A deep understanding of plant stress response mechanisms which are regulated at the physiological, biochemical, and molecular level is critical to achieving this goal. Current research highlights the significance of metabolic reprogramming and the accretion of secondary metabolites in plant’s adaptation to abiotic stress. Advances in metabolomics have facilitated the characterization of metabolites triggered by stress, offering insights into the metabolic adjustments plants make in response to environmental challenges. However, the complex polygenic nature of stress retorts, the influence of environmental factors, and the difficulty in pinpointing specific metabolites associated with distinct stress conditions remain significant challenges. The integration of metabolomics with genomic approaches, focusing on the genetic regulation of metabolite biosynthesis and pathways, offers promising prospects for increasing stress tolerance in crops. Such integrated strategies are crucial for ensuring sustainable agriculture practices and improving crop resilience in an era of climate change.
