Plant Development: Suppression the Key to Asymmetric Cell Fate.
A new study shows that SPEECHLESS determines cell fate in the stomatal lineage but is inherited equally by daughter cells following an asymmetric cell division. The polarity determinant BASL acts as a MAPK scaffold, targeting SPEECHLESS for degradation in the larger daughter cell.
