The promoters of several E2F‐regulated genes identified in plants contain a variety of E2F motifs, notably a composite element consisting of a “CDE‐like element” C/GGCGG on one strand, described as repressor in animals, associated with an E2F element on the complementary strand. This detailed study throughout plant development using ribonucleotide reductase promoters, allows us to propose a model, where E2F and composite elements play a dual role. Such regulation is mainly conditioned by the availability of E2F factors in tissues and during the cell cycle in tobacco.
