The growing plant root undergoes a variety of developmental steps that determine thickness and branching as the roots elaborate. Moreno-Risueno et al. identify a suite of transcription factors, some of which mobilize between cells, that regulate shifting fates during root growth. The same set of transcription factors governs identity and proliferation of the stem cells as well as the fates of daughter cells.
