Conserved or cluster-specific cis-elements. (a) Motifs identified in clusters N1, N8, N3, N9, N10, N12, and N13. These clusters were induced by light or ABA. A common motif ABRE united genes within these clusters. Additional motifs that distinguish genes in individual clusters are included (I-Box or DRE). See Table 2 for identified motifs. (b) 5'-regulatory motifs identified from clusters N0 and N19. The WRKY motif was identified in both clusters, whereas the HSF motif was present only in cluster N0.
