Global view of gene expression profiling under drought treatment. a Principal component analysis (PCA) of the RNA-seq data. b-c Venn diagrams showing the number of DEGs identified at two sampling points of PR403 and PY6. |log2FC| ≥1 and padj < 0.05 were used as thresholds for DEG identification. PR403/PY6_CK40, PR403/PY6_CK22, and PR403/PY6_CK20 in (a-c) represent untreated PR403/PY6 RNA-seq samples that were harvested at sampling point 40, 22, and 20, respectively. PR403/PY6_22 and PR403/PY6_20 in (a-c) represent drought treated PR403/PY6 RNA-seq samples that were harvested at sampling point 22 and 20, respectively
