#SCPH28 | Zoology
  1. A transcription factor encoded by the SHOOT MERISTEMLESS gene is expressed in shoot meristem cells and maintains them in their undifferentiated state.
  2. A homeobox transcription factor encoded by CLAVATA gene is expressed in the organizing center and initiates a signal to the overlying cells to behave as stem cells.
  3. Shoot meristem cell secrete proteins encoded by WUS family that antagonize CLV expression thereby restricting the size of shoot meristems.
  4. A transcription factor encoded by the SHOOT MERISTEMLESS gene is expressed in shoot meristem cells and maintains them in their differentiated state.
