Overview of root branching meristem-enriched genes. A and B, The heatmaps show the expression (log2 FC) of meristem-enriched genes upregulated (A) or downregulated (B) during root branching. C, Representation of the meristem-enriched genes in different expression clusters. The meristem-enriched genes were in particular overrepresented in transiently upregulated (dome) clusters in magenta frames and constitutively downregulated (down) clusters in blue frames. Orange and green frames indicate constitutively upregulated (up) and transiently downregulated (valley) clusters, respectively. DRBG, Downregulated root branching DEGs; URBG, Upregulated root branching DEGs. D, Enrichment analysis of the meristem-enriched genes that were upregulated during root branching. The graph shows enriched biological process and molecular function gene ontology (GO) terms. Node size is scaled by the P-value of the enriched GO term, and node color (from green to red) is determined by the enrichment fold of the term. Negative enrichment folds are faded. The outer green band is determined by the subset ratio. The graph was generated by PLAZA version 4.5 (https://bioinformatics.psb.ugent.be/plaza/versions/plaza_v4_5_dicots/).
