Multiomics provides insights into dynamic changes of aromatic profile during flue-curing process in tobacco (Nicotiana tabacum L.) leaves.

ABSTRACT: Tobacco (Nicotiana tabacum L.) is a globally crop due to its distinctive flavor and economic value. In this study, we systematically analyzed the dynamic changes in volatile substances, broad-spectrum metabolites, enzymes, and biochemical compounds in tobacco leaves during flue-curing process. Combining metabolomics with enzyme activity and biochemical analysis, we identified that 43℃ is a critical period for enzyme activity and metabolite transitions, while 45 ℃ requires stringent moisture control. During the T3 stages, phenolic acids, amino acids, and derivatives were notably enriched, with increases of 19.58-fold, 18.59-fold, and 17.33-fold in lmmn001643, MWS20633g, and Lmhn004756, respectively. These compounds may serve as candidate biomarkers for non-volatile compounds. Aroma dynamics
