Groundnut Metabolomic Shifts Under Drought With Microbial Biostimulants

Supplementary data from a field trial analyzes metabolomic variations in groundnut triggered by an encapsulated microbial biostimulant for drought adaptation. The study identified 52 altered metabolites and 25 significantly altered metabolic pathways under water deficit conditions. The research was conducted by Sakthi Uma Devi Eswaran and published in 2026.

Use Cases

• Analyze the 52 altered metabolites, including sugars, fatty acids, and amino acids, to identify biomarker signatures for drought stress.
• Investigate the 25 metabolic pathways altered by biostimulant inoculation to understand drought adaptation mechanisms in groundnut.
• Correlate metabolomic shifts with physiological and yield attributes from the field trial to model biostimulant efficacy.
• Use partial least square discriminant analysis (PLS-DA) results to classify groundnut samples based on their metabolomic profiles under drought.

Strengths

• Identifies a specific set of 52 altered metabolites, providing a concrete biochemical profile.
• Pathway enrichment analysis reveals 25 metabolic pathways significantly altered under drought.
• Data is derived from a controlled field trial with statistically significant (p < 0.05) impact measurements.

Limitations

• The dataset is small in file size (812.4 KB), indicating limited raw data or processed summary results.
• The specific sample size (number of groundnut plants or replicates) and raw data structure are not provided.
• Geographic location and specific time range of the field trial are unknown, limiting contextual analysis.
