PCA of Transcriptomic Profiles in Sweet Potato Leaves under Drought Stress

Supporting dataset for Figure 1a: Principal Component Analysis (PCA) of transcriptomic profiles 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 1a illustrates PCA results based on global gene expression patterns from sweet potato leaves sampled under control and drought stress at two developmental stages. The PCA highlights clear clustering between treatment groups, indicating distinct transcriptomic responses. ### This dataset includes:- Gene expression matrix (Sheet 1 of `PCA_transcriptomics_data.xlsx`)- Sample group metadata (Sheet 2 of the same file)- R script used for PCA analysis and figure generation (`PCA_transcriptomics_plot.R`)- Final PCA figure (`PCA_transcriptomics_plot.pdf`)- Metadata (`README.md`) and license file (`LICENSE`) This resource enables full reproducibility of Figure 1a and facilitates open reuse in plant drought transcriptomics research.
