#SCPH01 Biochemistry

A transcription factor encoded by the SHOOT MERISTEMLESS gene is expressed in shoot meristem cells and maintains them in their undifferentiated state.
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.
Shoot meristem cell secrete proteins encoded by WUS family that antagonize CLV expression thereby restricting the size of shoot meristems.
A transcription factor encoded by the SHOOT MERISTEMLESS gene is expressed in shoot meristem cells and maintains them in their differentiated state.
