Table IV.

The occurrence of novel cis-regulatory elements in the promoters of genes whose expression changed early or late in response to P withdrawal in the experiments reported here (Tables I and II) and cis-regulatory elements previously identified as common to genes whose expression responded to P starvation

The occurrence of these cis regulatory elements in the promoters of all genes on the Affymetrix GeneChip are given for comparison. —, not determined.
