Significance
          The whole-cell file lineages of plant roots are derived from a small group of initials that surround a functional and structural center, called the quiescent center (QC). It’s known that the QC maintains the directly abutting stem cells undifferentiated, but the mechanism for the maintenance is not entirely clear. Using a system that effectively blocks plasmodesmata in the QC, we show that QC-derived signals symplastically instruct the status of surrounding stem cells. Via directing local auxin biosynthesis, cell-to-cell communication between the QC and neighboring cells provides positional information for stem cell maintenance. Our results reveal a tight link between symplastic communication and auxin-dependent stem cell maintenance.</jats:p
