Volcano Plot of Differentially Accumulated Metabolites in Sweet Potato Leaves under Drought Stress

This dataset supports Figure 6 in the article “Unveiling Stage-Specific Flavonoid Dynamics Underlying Drought Tolerance in Sweet Potato (Ipomoea batatas L.) via Integrative Transcriptomic and Metabolomic Analyses.” Figure 6 presents volcano plots of differentially accumulated metabolites (DAMs) in sweet potato leaves subjected to drought stress at distinct developmental stages. The figure includes three pairwise comparisons: CK vs. DS1: Drought stress during the branching and tuber formation stage CK vs. DS2: Drought stress during the storage root expansion stage DS1 vs. DS2: Comparison between the two drought stress stages Each volcano plot highlights metabolites with |log₂ fold change| ≥ 1 and VIP ≥ 1 as significantly up- or down-regulated. Top 5 up- and down-regulated metabolites are annotated by biochemical class. Dashed lines represent the significance thresholds. The dataset includes: Input Excel files for metabolite comparisons (DAM data) R script for generating volcano plots Final high-resolution figure in PDF format This module enables full reproduction of Figure 6 and facilitates reuse of metabolomics comparison data under varying drought conditions in sweet potato.
