Motif enrichment analysis. A: GO-functional gene sets for motifs of length 6 and 7 bases. B: GO-functional gene sets for motifs of 8 bases in length. C: GE-groups. D: Gene expression-based clustering . The darkness of each cell is proportional to the z-score of the corresponding motif in that functional gene set.
