DESCRIPTION:Plant form is controlled by post-embryonic organ formation. Or
 gans initiate from the shoot apical meristem\, an undifferentiated structu
 re that contains a population of self-renewing stem cells.  During organ i
 nitiation\, founder cells on the periphery of the meristem are recruited i
 nto the forming organ primordium where they undergo dramatic changes in ge
 ne expression\, cell division\, and hormone signaling.  Initiating organs 
 are separated from the shoot apical meristem by a boundary region that is 
 characterized by small\, slowly-dividing cells. The boundary serves to iso
 late the primordium from the meristem and is critical for coordination of 
 organogenesis and meristem maintenance. We study several boundary-specific
  transcription factors in Arabidopsis thaliana.  These transcription facto
 rs function to specify boundary identity and to limit cellular growth.  Ou
 r progress in understanding the networks regulated by boundary transcripti
 on factors will be presented.
