A Trio of Transcription Factors Control Vascular Development in Arabidopsis Stems. Following activation of receptor kinases present at the surface of procambium cells, the transcription factors TMO6, WOX14, and LBD4 are induced, leading to proliferation of the procambium and differentiation into phloem cells. Note the progressive shrinking of the procambium and phloem pool as the signal through the pathway diminishes. pxF is a triple mutant lacking PXY and two related receptors. (Adapted from Smit et al. [2020], Figures 2 and 3.)
