In the face of increasing environmental challenges such as climate change, enhancing plant resilience to stress has become a critical goal in agriculture. Metabolomics-assisted breeding (MetAB) has emerged as a promising approach that integrates metabolomics with traditional breeding strategies to develop stress-tolerant plant varieties. This chapter explores the principles, methodologies, and potential applications of MetAB in improving plant stress responses. Metabolomics, a powerful tool in systems biology, enables comprehensive analysis of metabolites present in plant tissues. By profiling the metabolome under stress conditions, MetAB provides valuable insights into the biochemical pathways and metabolic networks involved in stress tolerance mechanisms. Through the identification of stress-responsive metabolites and metabolic signatures associated with stress adaptation, MetAB facilitates the selection of superior plant genotypes with enhanced stress resilience. Key components of MetAB include metabolite profiling, biomarker discovery, and integration with other omics tools. Metabolite profiling techniques such as mass spectrometry and nuclear magnetic resonance spectroscopy allow the high-throughput analysis of diverse metabolites, while advanced statistical and bioinformatics tools aid in biomarker identification and selection. Integration of metabolomics data with genomic information enables the identification of candidate genes and quantitative trait loci underlying stress tolerance traits, facilitating targeted breeding efforts. The application of MetAB holds immense potential for crop-improvement programs aimed at developing stress-tolerant varieties with increased yield stability and resilience to biotic and abiotic stressors. By harnessing the synergistic effects of metabolomics and breeding, MetAB offers a novel approach to accelerate the development of climate-resilient crops, thereby contributing to global food security and sustainable agriculture.
