Venn diagrams summarizing the overlap between predicted targets and ChIP-Seq identified targets of KN1, FEA4 and O2. Blue circles are the number of predicted targets for tissue-specific GRN (leaf, root, SAM and seed) or the Plant Transcriptional Regulatory Map (PlantReg); red circles are the number of targets identified by ChIP-Seq. KN1 and O2 were not expressed in some tissues (Not expressed). FEA4 and O2 were not included in PlantReg database (No data). P-values were calculated from one-tail Fisher’s exact tests and significant overlaps were indicated with *** (p-values less than 0.01) or * (p-values less than 0.05)
