In higher plants, shoot organs such as leaves, branches, and flowers are generated from the shoot apical meristem (SAM), a small group of undifferentiated cells located at the tip of the shoot. The SAM maintains its pluripotency and simultaneously produces lateral organs at its periphery. The SAM arises during embryogenesis and its positioning requires axis-dependent embryo patterning and compartmentalization of the embryo apex. Here, we introduce major factors involved in these processes in Arabidopsis thaliana and discuss how the embryonic SAM is established.
