Figure 5.

Presence in A. thaliana promoters of the three PLM classes characterized by a sharp functional window and preferentially located in the [-39, -26] region. The square represents the 14927 A. thaliana promoters (the whole promoter set) with experimentally known TSS. The central Venn diagram illustrates the overlaps between the three PLM classes in promoters. In the [-39, -26] region, 2606 promoters contained a canonical TATA-box, 4151 a TATAΔ-PLM and 2645 a TC[-39,-26]-PLM. In black the overlap between the three classes. In blue, the promoter sets analysed in the study, i.e. the promoter sets with PLMs from only one of the three classes and the promoter set that does not contain PLMs of the three classes.
