Metabolomic Characterization of Chestnut Defense Reprogramming Under Pest Stress

713 identified metabolites from Castanea mollissima (Chinese chestnut) under Oligonychus ununguis (spider mite) feeding stress. The data includes 83 flavones, 100 flavonols, 221 phenolic acids, and other compound classes. Author Xinfang Zhang published the dataset on figshare in 2026.

Use Cases

• Analyze changes in specific metabolite classes like flavones and flavonols under biotic stress.
• Compare the abundance of 221 phenolic acids against other compound groups in plant defense.
• Investigate correlations between biological replicates based on the reported high reproducibility (r=0.989–0.998).
• Model plant defense reprogramming using the detailed profile of 713 identified metabolites.

Strengths

• Contains 713 identified metabolites across 13 distinct classes.
• Reports high reproducibility among three biological replicates per sample (correlation coefficients r=0.989–0.998).
• Provides detailed breakdowns for major compound classes, including 100 flavonols and 221 phenolic acids.

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 small in scale (812.9 KB), indicating limited scope.
