title: Stem Cell Fate versus Differentiation: the Missing Link.
abstract: The shoot apical meristem provides a microenvironment that ensures stem cell fate and proliferation via homeostasis between WUSCHEL (WUS) activity and CLAVATA signalling. New data from maize and arabidopsis reveal that an evolutionarily conserved signal deriving from primordium cells links WUS transcription to the morphogenetic programme.
