Table 2_Widely targeted metabolomics reveals maturity-associated metabolic differences and

Widely targeted metabolomics identified 72 differential metabolites in Dafang County and 51 in Weining County between early and late harvest stages. The dataset includes leaf phenotype, color, enzyme activity, and sensory style scores for Yunyan 87 tobacco leaves collected at five maturity stages from two distinct ecological regions.

Use Cases

• Analyze maturity-associated metabolic differences based on the 72 and 51 differential metabolites identified in cured leaves.
• Investigate relationships between sensory style characteristics and physiological measurements like SPAD values and enzyme activities mentioned in the description.
• Study regional ecological influences on flavonoid and antioxidant-related metabolic patterns based on environmental correlation analysis.
• Validate transcriptional-metabolite relationships for flavonoid biosynthesis and sugar metabolism pathways using the RT-qPCR data referenced.

Strengths

• Includes metabolomic data for 72 differential metabolites in one region and 51 in another, providing quantitative comparisons.
• Integrates multiple data types: leaf phenotypes, color parameters, SPAD values, key enzyme activities (POD, LOX, PPO, SPS), and sensory style scores.
• Data collection spans five distinct maturity stages (T1 to T5) across two representative ecological regions (Dafang and Weining Counties).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (9.6 KB), indicating a limited scope likely focused on summary or processed results rather than raw instrument data.
