All informative motifs obtained from a single microarray experiment, analyzing the genome-wide response of a MSN2/MSN4 mutant strain when treated with 0.3mM H2O2. Rows correspond to motifs and columns to (equally sized) groups of genes with a similar expression value (log-ratio). One of these motifs (PAC) is associated with down-regulated genes, while the three others (Rpn4, Yap1, Puf3) are associated with different populations of up-regulated genes.
