DEGs related to phytohormones in three samples. a Hierarchical cluster of the DEGs related to phytohormones in X2 (13 DPA), X3 (19 DPA), and X4 (25 DPA). Red: high expression; Blue: low expression. b Scatterplot of KEGG pathway enrichment in X2 (13 DPA) vs X3 (19 DPA) (FDR< 0.05). c Scatterplot of KEGG pathway enrichment in X3 (19 DPA) vs X4 (25 DPA) (FDR< 0.05). Rich factor is the ratio of the number of DEGs to the number of background genes in a KEGG pathway. d GO classification of DEGs in X2 (13 DPA) vs X3 (19 DPA) (FDR< 0.05). e GO classification of DEGs in X3 (19 DPA) vs X4 (25 DPA) (FDR< 0.05). The top 30 enriched GO classifications are listed. Stars above bars indicate the amounts of differentially expressed genes are significantly higher or lower than the amounts of genes in random samples from the GO classification of all genes. f DEGs related to phytohormones enriched biological processes in X3 (19 DPA) vs X4 (25 DPA). g DEGs related to phytohormones enriched cellular component in X3 (19 DPA) vs X4 (25 DPA). h DEGs related to phytohormones enriched molecular function in X3 (19 DPA) vs X4 (25 DPA). The different color frames indicate the extent of significance. Yellow: significant; Red: extremely significant. i Number of up- and down-regulated DEGs in two sample pairs X2 (13 DPA) vs X3 (19 DPA), and X3 (19 DPA) vs X4 (25 DPA)
