SCR function in QC and ground tissue. SHR moves from the stele to the QC and ground tissue cells. In the QC and ground tissue stem cells, SCR expression is induced by SHR and maintained by autoregulation. The inductive capacity of SHR is lost on SCR expression. The QC prevents SCR induced periclinal cell division in the ground tissue stem cell. SCR induces the periclinal division in the ground tissue stem cell daughter. SCR mediates rapid endodermal (SHR) and cortical (C) fate separation and segregation of factors required for execution of the periclinal division. Residual SHR and SCR in the outer cell is degraded. In the endodermis, SCR prevents SHR movement to the neighboring cortex cell file, thereby preventing additional periclinal divisions.
