cis-Elements identified in the promoters of SA-repressed genes

Analysis was performed on a subset of 304 genes with unambiguous probe-to-gene assignment. The number of appearances of each motif in promoters (−1,000 bp) of SA-repressed genes (fobs) was compared to its frequency in promoters of genes of the whole genome (ftheor) by a general bootstrapping technique. Only motifs significantly over- or underrepresented (P < 0.05) are listed.
