Significantly over-represented motifs in promoters of genes that change in expression during leaf development and senescence. The table shows the significant promoter motifs (e-value cutoff less than e-05) and the number of elements (in italics) found in the set of promoters of genes classified in one of the six expression profiles [47]. For leaf analysis, multiple profiles were combined to identify significant motifs. Leaf profiles 2 and 3 were combined, while profile 4 was pooled with genes decreasing in stage L-V. Profiles 5 and 6 did not include a sufficient number of genes to identify significant motifs. Profiles 7 and 8 were pooled into one profile. Profile 9 included additional genes that increased in expression between stages L-IV and L-V. Where gene sets were too large for analysis, the top 425 or 450 genes (based on magnitude of fold change) were analyzed
