Description

<jats:p> <jats:italic>APETALA2</jats:italic> ( <jats:italic>AP2</jats:italic> ) plays an important role in the control of Arabidopsis flower and seed development and encodes a putative transcription factor that is distinguished by a novel DNA binding motif referred to as the AP2 domain. 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 <jats:italic>Arabidopsis</jats:italic> . The <jats:italic>RAP2</jats:italic> 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. <jats:italic>RAP2</jats:italic> genes are differentially expressed in flower, leaf, inflorescence stem, and root. Moreover, the expression of at least three <jats:italic>RAP2</jats:italic> genes in vegetative tissues are controlled by <jats:italic>AP2</jats:italic> . Thus, unlike other floral homeotic genes, <jats:italic>AP2</jats:italic> is active during both reproductive and vegetative development. </jats:p>
