Description
72 and 51 differential metabolites were identified in cured tobacco leaves from two ecological regions in Guizhou, China, at different harvest times. The dataset includes measurements of leaf phenotypes, color parameters, SPAD values, enzyme activities, and sensory style scores across five maturity stages. It was authored by Chenyu Cai and last updated on 2026-05-21.
Use Cases
Identify maturity-associated metabolic biomarkers based on the 72 and 51 differential metabolites identified.
Model relationships between environmental variables and metabolite patterns based on the radiation-, temperature-, precipitation-, and soil-related correlation analysis.
Analyze the link between physiological traits (like SPAD values and enzyme activities) and sensory style characteristics mentioned in the evaluation.
Investigate transcriptional-metabolite relationships for flavonoid biosynthesis and sugar metabolism pathways based on the RT-qPCR validation data.
Strengths
Includes metabolomic data for 72 differential metabolites in one region and 51 in another, providing a basis for comparative analysis.
Integrates multiple data types: phenotypic observations, color parameters, SPAD values, enzyme activities, sensory scores, environmental variables, and gene expression data.
Samples were collected from two distinct ecological regions (Dafang and Weining Counties) at five specific time points, allowing for spatiotemporal analysis.
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 very small (9.2 KB), indicating a limited scope, likely summary statistics rather than raw observational data.
