Abstract

The no apical meristem/cup-shaped cotyledon (NAM/CUC3) transcription factors, which include the Arabidopsis CUC proteins, are evolutionary conserved factors that play essential roles in the establishment and function of boundaries, small domains that act both as frontiers and morphogenesis-organizing centers. In this chapter, we will review structural data on the NAM/CUC3 proteins and retrace their evolution within the larger family of NAM, ATAF1, ATAF2, and CUC (NAC) transcription factors, and provide new data about their possible origin. We will then highlight the multiple roles they play during the development of the aerial part of plants. Finally, we provide clues about how they contribute to the regulation of plant morphogenesis by showing how these genes are integrated in complex regulatory networks entailing hormones, miRNA, transcription factors, and chromatin factors and how they may modify plant cellular behavior.
