Fig. 3: Jasmonic acid-mediated gene expression during petal abscission.

a Venn diagrams showing the overlap between genes down-regulated in dad1 vs. the WT, up-regulated in jazD vs. the WT, up-regulated in the WT after 1 h JA treatment, and up-regulated in the WT after 24 h JA treatment. b Hierarchical clustering of 70 high-confidence JA-regulated genes during petal abscission. The heatmap shows the Log₂ fold-change of these genes in the RNA-seq data in a. c GO-term enrichment analysis using the above 70 high-confidence JA-regulated genes. Selected GO terms related to plant hormones, cell death, defense response and stress response are shown with their associated –Log₁₀ adjusted p-value. The p-values for GO analysis are obtained by converting the Z-scores based on a two-tailed Z-test. d Cis-motif enrichment in 70 high-confidence JA-regulated genes during petal abscission. Sequence-logo representation of nucleic acid multiple sequence alignment and –Log₁₀ adjusted p-values converted from Z scores based on a two-tailed Z-test are shown. e Interactive graph view of GO terms generated by REVIGO. The node radius indicates the specificity, and the color shading corresponds to the p-values. Highly similar GO terms are linked by edges, with edge thickness indicating the degree of similarity.
