Table 4_Widely targeted metabolomics reveals maturity-associated metabolic differences and

Widely targeted metabolomics identified 72 differential metabolites in tobacco from Dafang County and 51 in Weining County between early and late harvest stages. The dataset includes leaf phenotype measurements, enzyme activity data, sensory style scores, and environmental variables for Yunyan 87 tobacco leaves collected at five maturity stages. Chenyu Cai published this data on figshare in May 2026 under a CC-BY-4.0 license.

Use Cases

• Modeling the relationship between harvest maturity and sensory style scores based on the described sensory evaluation data.
• Analyzing region-specific metabolic patterns linked to environmental variables based on the environmental correlation analysis mentioned.
• Investigating transcriptional-metabolite relationships in flavonoid and sugar metabolism pathways based on the RT-qPCR validation data described.

Strengths

• Includes multi-modal data: metabolomic profiles, phenotypic measurements, enzyme activities, and sensory scores.
• Provides a direct comparison between two distinct ecological regions (Dafang and Weining counties) and five maturity stages.
• Dataset is openly available under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 11.3 KB, indicating limited scope or a summary-level dataset.
