Figure 6. Model for the transcriptional regulation of LMW glutenin gene expression.

Figure 6

Intensity of geometric forms marks the frequency of these elements present in the promoter types or developmental phases. Most important cis-acting elements and the possible TF interactions are labelled. A - Promoter profile of LMW glutenin genes following a continuously growing expression; B – Promoter profile of gene types following a normal distribution in expressed transcripts during the seed development; C – model for transcriptional regulation in the early phase and mid phase of expression. Conserved non-coding sequence regions (CRE1, CRE2 and CRE3) are labelled with open rectangles. Developmental stages are labelled with DPA.
