Heatmap of Differentially Expressed Genes in Sweet Potato Leaves under Drought Stress

Supporting dataset for Figure 1b: Hierarchical clustering heatmap of differentially expressed genes (DEGs) in sweet potato leaves under drought stress. This dataset accompanies the article: **“Unveiling Stage-Specific Flavonoid Dynamics Underlying Drought Tolerance in Sweet Potato (*Ipomoea batatas* L.) via Integrative Transcriptomic and Metabolomic Analyses”** Figure 1b shows a clustering heatmap of the top 100 DEGs based on transcriptomic data from sweet potato leaves collected under control and drought conditions at two developmental stages. Genes were selected based on expression magnitude, normalized using Z-score transformation, and clustered via k-means (k = 9). Treatment group and gene cluster annotations are included in the heatmap. ### This dataset includes:- Gene expression matrix (Sheet 1 of `Clustering_heat_map_transcriptomics_data.xlsx`)- Sample grouping metadata (Sheet 2)- R script used to generate the heatmap (`Clustering_heat_map_transcriptomics_plot.R`)- Output figure (`Clustering_heat_map_transcriptomics_plot.pdf`)- Supplementary documentation (`README.md`) and open license (`LICENSE`) This resource supports full reproducibility of Figure 1b and promotes reuse in transcriptomic analyses of drought responses in sweet potato.
