Overrepresentation analysis of cis-regulatory motifs in the promoters of early EBE target genes. A, Overrepresentation of the GTCGAC motif in the promoters of the 48 early target genes compared with the background. B, The TATCC motif (SRE) is more abundant in the promoters of the 34 down-regulated EBE early target genes than in the background data set. C and D, Overrepresentation of TCP target sites in the promoters of the 48 EBE downstream targets. All analyses were performed using the POBO program. Dashed lines indicate the occurrence of motifs in EBE downstream genes, and solid lines indicate the occurrence of motifs in the background data set.
