In this study we show that the AP2 domain containing or RAP2 (related to AP2) family of proteins is encoded by a minimum of 12 genes in Arabidopsis . The RAP2 genes encode two classes of proteins, AP2-like and EREBP-like, that are defined by the number of AP2 domains in each polypeptide as well as by two sequence motifs referred to as the YRG and RAYD elements that are located within each AP2 domain. RAP2 genes are differentially expressed in flower, leaf, inflorescence stem, and root. Moreover, the expression of at least three RAP2 genes in vegetative tissues are controlled by AP2 . Thus, unlike other floral homeotic genes, AP2 is active during both reproductive and vegetative development.

Ainsi sont decrits les acides nucleiques servant au codage des polypeptides de modulation de la lignine ainsi que les procedes par lesquels on utilise de tels acides nucleiques pour produire des plantes transgeniques dont la teneur en lignine est variable.

L'invention concerne en outre l'utilisation de ces promoteurs ou elements de controle de promoteur pour moduler les niveaux de transcrits dans des plantes et des plantes contenant ces promoteurs ou elements de controle de promoteur.

We show here that in addition to its functions during flower development, AP2 activity is also required during seed development. We isolated the AP2 gene and found that it encodes a putative nuclear protein that is distinguished by an essential 68-amino acid repeated motif, the AP2 domain. Consistent with its genetic functions, we determined that AP2 is expressed at the RNA level in all four types of floral organs-sepals, petals, stamens, and carpels-and in developing ovules. Thus, AP2 gene transcription does not appear to be spatially restricted by the floral homeotic gene AGAMOUS as predicted by previous studies. We also found that AP2 is expressed at the RNA level in the inflorescence meristem and in nonfloral organs, including leaf and stem. Taken together, our results suggest that AP2 represents a new class of plant regulatory proteins that may play a general role in the control of Arabidopsis development.
