a Confocal images of calcofluor white stained roots. Blue arrows indicate cell files showing a cell wall reinforcement, sign that they are undergoing a protophloem differentiation process. Scale bars correspond to 50 μm. b Frequency of ectopic protophloem differentiation in roots. Letters indicate statistical groups (χ2 test with Benjamini–Hochberg correction). c Schematic model of autocrine and paracrine signaling mediated by the CLE33/45 peptides via the BAM3 receptor.
