Summary
The metabolome, encompassing small molecules within organisms, provides critical insights into physiology, environmental influences, and stress responses. Metabolomics enables comprehensive analysis of plant metabolites, uncovering biomarkers and mechanisms underlying stress adaptation. Regulatory genes such as MYB and WRKY are central to secondary metabolite synthesis and environmental resilience. By integrating metabolomics with genomics, researchers can explore stress-related pathways and advance crop improvement efforts. This review examines metabolomic profiling under stress conditions, emphasizing drought tolerance mechanisms mediated by amino acids and organic acids. Additionally, it highlights the shikimate pathway's pivotal role in synthesizing amino acids and secondary metabolite
