KEGG Pathway Enrichment of Differentially Accumulated Metabolites in Sweet Potato Leaves under Drought Stress

This dataset supports Figure 7 in the article “Unveiling Stage-Specific Flavonoid Dynamics Underlying Drought Tolerance in Sweet Potato (Ipomoea batatas L.) via Integrative Transcriptomic and Metabolomic Analyses.” Figure 7 presents KEGG pathway enrichment analysis results of differentially accumulated metabolites (DAMs) identified in sweet potato leaves under drought stress at distinct developmental stages. The top 30 enriched KEGG metabolic pathways are visualized for three pairwise comparisons: CK vs. DS1 (drought stress applied during the branching and tuber formation stage) CK vs. DS2 (drought stress applied during the storage root expansion stage) DS1 vs. DS2 (inter-stage comparison) Each plot shows enriched pathways with their corresponding Rich factor, P-value, and number of DAMs involved. The enrichment was based on pathway annotation and classification using KEGG database resources. The repository includes: Raw enrichment outputs (CK1_vs_DS1_KEGG.xlsx, CK1_vs_DS2_KEGG.xlsx, DS1_vs_DS2_KEGG.xlsx) Pathway classification reference (KEGG_pathway_classification.xlsx) R script for figure generation (KEGG_enrichment_metabolomics_plot.R) Final figure (KEGG_enrichment_metabolomics_plot.pdf) README and LICENSE files These resources enable full reproducibility of the figure and can be reused for comparative pathway analysis in other plant metabolomics studies.
