In the root apical meristem, the cells are produced in two directions. In the shoot apical meristem, cells are only created in one direction. The shoot apical meristem may exist at the tips of plants, as in many dicots, or may start slightly below the soil and generate leaves which grow upward, like most monocots. The shoot apical meristem of Arabidopsis thaliana contains a reservoir of pluripotent stem cells that functions as a continuous source of new cells for organ formation during development.

The shoot apical meristem (SAM) is formed during early embryogenesis and gives rise to the entire aboveground plant body (Aichinger et al., 2012). Establishment and maintenance of SAM depends on an auto-feedback signaling loop comprising the WUSCHEL (WUS) and CLAVATA (CLV) in Arabidopsis (Brand et al., 2000; Schoof et al., 2000). we know about this process, and how we now perceive the shoot apical meristem is a consequence of a long history of research, through which has emerged a number of key models, influ-ential to many but traceable back to a dominant few. The many facets of the shoot apical meristem provide tremendous scope for different interpretations. Below, in
