Continuous growth and organ development from the shoot apical meristem (SAM) requires a precise coordination of stem cell proliferation, commitment of stem cell descendants to diverse differentiation pathways and establishment of morphological meristem-to-organ boundaries. These complex biological processes require extensive integration of several components of cell-to-cell signaling and gene regulatory networks whose coordinated actions have an impact on cell division and growth Here we review the current knowledge of gene networks involved in organogenesis from the SAM in higher plants. We focus on recent advances to show how the interaction between transcriptional regulators, hormonal crosstalk and physical stress regulates the establishment and maintenance of meristem-to-organ boundaries.
