Meristems: start your signaling.

Author information

Department of Biology, University of Michigan, Ann Arbor 48109-1048, USA.


All of the cells of the shoot apex are derived from a small number of stem cells in the center of the shoot meristem. Hence, cell lineage plays no role in establishing pattern formation or cell fate at the shoot apex. Growing evidence has implicated a number of cell signaling pathways in regulating shoot meristem development and organ formation. These signaling pathways include receptor-mediated signaling, protein movement via plasmodesmata, and potential feedback loops.
