Pumpkin Seedling Metabolite Data from GABA Treatment Study

226.5 KB of research data from a study investigating the effect of exogenous γ-aminobutyric acid (GABA) on 2-acetyl-1-pyrroline (2-AP) biosynthesis in pumpkin seedlings. The dataset, authored by Jingjing Chang and last updated in April 2026, likely contains measurements of metabolite contents, enzyme activities, and gene expression levels. The study reports a 72.4% increase in 2-AP content and a 7.8-fold increase in glutamate following GABA treatment.

Use Cases

• Modeling the metabolic flux between GABA, glutamate, proline, and 2-AP biosynthesis based on the described pathway.
• Analyzing the correlation between enzyme activity (P5CS, ProDH, BADH) and gene expression levels mentioned in the study.
• Investigating the relationship between exogenous GABA application and plant growth metrics like leaf area and fresh weight.
• Developing predictive models for aroma quality improvement in cucurbits based on precursor metabolite levels.

Strengths

• Specific quantitative results are reported, including a 72.4% increase in 2-AP and a 7.8-fold increase in glutamate.
• The study design includes multiple data types: metabolite quantification, enzyme activity assays, and gene expression analysis.
• The dataset is openly available under a CC-BY-4.0 license, facilitating reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data is contained in a 226.5 KB DOCX file, suggesting a limited scope and likely a small sample size.
