Tobacco Leaf Metabolite Response to Curing Temperature Variation

A study by Shengjiang Wu, published in 2026, analyzed the metabolic reprogramming of tobacco leaves under different flue-curing temperatures. The dataset contains 7,233 differentially expressed metabolites identified via a nontargeted metabolomics approach, comparing fresh leaves to those cured at 44°C and 46°C. Pathway analysis indicated significant effects on lipid metabolism, fatty acid biosynthesis, and hormone signal transduction.

Use Cases

• Modeling temperature effects on plant lipid metabolism based on metabolite differential expression.
• Identifying biomarkers for leaf quality based on temperature-responsive metabolites like malonic acid and indole-3-acetic acid.
• Analyzing metabolic pathways related to senescence and structural traits in cured tobacco leaves.

Strengths

• Contains 7,233 differentially expressed metabolites, providing a broad metabolic profile.
• Directly compares two distinct temperature treatments (44°C and 46°C) against a fresh leaf control.
• Includes pathway enrichment analysis results for lipid metabolism and hormone signal transduction.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The geographic origin of the tobacco samples is not specified.
