As global climates shift, plants are increasingly exposed to biotic and abiotic stresses that adversely affect their growth development, ultimately reducing agricultural productivity. To counter these stresses, produce secondary metabolites (SMs), which critical biochemical essential compounds serve as primary defense mechanisms. These diverse compounds, such alkaloids, flavonoids, phenolic nitrogen/sulfur-containing act natural protectants against herbivores, pathogens, oxidative stress. Despite the well-documented protective roles of SMs, precise mechanisms by environmental factors modulate accumulation under different stress conditions not fully understood. This review provides comprehensive insights into recent advances in understanding functions SMs plant emphasizing regulatory networks biosynthetic pathways. Furthermore, we explored unique contributions individual SM classes responses while integrating findings across entire spectrum diversity, providing a resilience multiple conditions. Finally, highlight emerging strategies for harnessing improve crop through genetic engineering present novel solutions enhance sustainability changing climate.
