Fig. 3: Functional redundancy of CLE33 and CLE45 in BRX-mediated regulation of protophloem development.

a Root length at 10 days post germination. Letters indicate different statistical group (ANOVA, post hoc Tukey test). b Representative confocal images of calcofluor white stained roots. Red arrows indicate protophloem gap cells. Scale bars correspond to 100 μm. c Gap cell frequency quantification. Letters indicate statistical groups (χ2 test with Benjamini–Hochberg correction).
