Comprehensive Characterization of Metabolites in Multiplier Onion Bulbs and Identification of Regulatory Genes for Nutritional Improvement

Multiplier onion (Allium cepa var. aggregatum) is an economically important Allium crop that serves dual purposes as both a culinary ingredient and medicinal resource. Despite its widespread utilization, systematic characterization of its nutrient metabolism components remains limited, which has constrained the development of high-value cultivars with opti- mized nutritional profiles. In this study, we conducted a comprehensive metabolomic pro- filing of bulbs from five genetically distinct...
