FIGURE 6.
W-boxes are highly enriched in promoters of RRS1-dependent genes. POBO analysis of the motif distribution in 1000 bp promoters of RRS1-dependent genes. One thousand pseudo-clusters of the 250 RRS1-dependent genes, genes regulated by the temperature shift (Temp-shifted) and randomly selected genes from 35S:RPS4-HS (Genome-wide) are shown. Jagged lines indicate motif frequencies from which a fitted curve was derived. The W-box (TTGACY) is significantly over-represented in promoters of the RRS1-dependent genes compared to temperature-responsive genes or genes from the genome background with p-values < 0.0001.
