Table 1. Enrichment of defense-related cis-elements in promoters of ATP-responsive genes in wild-type seedlings.
The presence or absence of the indicated promoter elements in the presumptive promoters (−1,000 bp upstream of the transcriptional start site) was scored in 543 ATP-responsive genes and 33,693 genes of the Arabidopsis nuclear genome, and significant enrichment was tested by hypergeometric test. Italicized values indicate that the element was not significantly enriched (P > 0.05). Fold enrichment is calculated as (percentage presence in ATP-responsive genes)/(percentage presence in all Arabidopsis genes).
