Weighted gene co-expression network of stem samples. A Hierarchical cluster tree showing coexpression modules identified by WGCNA. Each leaf in the tree is one gene. The major tree branches constitute five modules labeled by different colors. B Module-sample relationship. C Module–bulbil number and -hormone contents relationships. The color bar represents the scale of the Spearman’s correlation. The color of the cell indicates the correlation coefficient between the traits: red indicates a high positive correlation and green indicates a high negative correlation. Asterisks indicate significant differences of these correlations detected by the Tukey’s HSD test (* P < 0.05 and ** P < 0.01) (B,C). D-H Heatmap is depicting the expression profile DEGs clustered in each module. I, Enrichment of KEGG pathway [34] (P-value < 0.05) annotation for five modular gene sets. The circle size of represents the counts of gene numbers involved in each KEGG pathway
