KEGG Pathway Heatmaps of Flavone and Flavonol Biosynthesis in Sweet Potato Leaves under Drought Stress

This dataset and R scripts support Figure 8 in the study “Unveiling Stage-Specific Flavonoid Dynamics Underlying Drought Tolerance in Sweet Potato (Ipomoea batatas L.) via Integrative Transcriptomic and Metabolomic Analyses.” Figure 8 illustrates KEGG-based heatmaps showing the log₂ fold changes of both gene expression (enzymes) and metabolite abundance involved in the flavone and flavonol biosynthesis pathway in sweet potato leaves subjected to drought stress at two developmental stages. Comparisons include: CK vs. DS1 (drought stress during branching and tuber formation stage), CK vs. DS2 (drought stress during storage root expansion stage), DS1 vs. DS2 (developmental comparison under drought). The heatmaps were generated using two input files: composition.xlsx: Log₂ fold changes of metabolites. enzyme.xlsx: Log₂ fold changes of genes (enzymes). Two R scripts (composition_heatmap_plot.R and enzyme_heatmap_plot.R) automate the visualization process, generating individual PDF heatmaps for each KEGG pathway group. All figures are saved in vector format (PDF) suitable for high-resolution publication.This module complements the multi-omics analysis of drought response in sweet potato and highlights the coordinated regulation of the flavonoid biosynthetic pathway.
