Association of core promoter motifs with tissue-specific expression. Shown for each class of genes are the percent that are up- or down-regulated by 2-fold or more at developmental transitions between hyphae and sporangia, sporangia and sporangia chilled to induce zoosporogenesis, chilled sporangia and swimming zoospores, and zoospores and germinated cysts forming appressoria. The values in the panel labeled “sporangia/hyphae”, for example, are based on the mRNA level in sporangia divided by hyphae. The gene classes contained in their promoters the INR+FPR supramotif without DPEP, only INR (i.e. INR with a weak or no FPR, and no DPEP), only FPR (i.e. an FPR with a weak or no INR, and no DPEP), or only DPEP.
