The giant shoot apical meristems of cacti should make it possible to more accurately map gene expression patterns relative to SAM zonation and leaf primordium sites. Mauseth, J. D. 2004. Giant shoot apical meristems in cacti have ordinary leaf primordia but altered phyllotaxy and shoot diameter.
The shoot apical meristem (SAM) generates above-ground aerial organs throughout the lifespan of higher plants. In order to fulfill this function, the meristem must maintain a balance between the self-renewal of a reservoir of central stem cells and organ initiation from peripheral cells. The shoot apical meristem generates stem, leaves, and lateral shoot meristems during the entire shoot ontogeny. Vegetative leaves are generated by the meristem in the vegetative developmental phase, while in the reproductive phase either bracts subtending lateral flower primordia (or paraclades), or … The apical meristem consists of upper promeristem and lower primary meristem. In primary meristematic region the cells are differentiated into three fundamental units.
