Smet et al. capture the transcriptional responses upon simultaneous TMO5/LHW induction and identify DOF2.1 as part of the cytokinin-dependent downstream responses. Furthermore, they show that DOF2.1 and its closest homologs control periclinal and radial procambium divisions in distinct zones of this tissue.
- cytokinin signaling
- DOF-type transcription factor
- plant vascular development
- procambium divisions
