Supplemental Data

Files in this Data Supplement:

• Supplemental Figure 1 - Supplemental figure 1. Effects of CLE peptides on the QC. GUS staining was performed in the QC25 roots after a 5-day treatment with or without peptides. The roots were cleared and observed under Nomarski optics, showing no visible changes in the QC cells. Seeds were germinated on media containing (A) no peptide, (B) CLV3s, (C) CLV3m or (D) CLV3p.
• Supplemental Figure 2 - Supplemental figure 2. Phenotypic analysis of the root of clv2-1. Confocal analysis of a 5-day old clv2-1 root, stained with PI, showing no evident changes in the root morphology. The scale bar represents 30 μm.
• Supplemental Figure 3 - Supplemental figure 3. Confocal observation of J0571 roots, after an 8-day treatment with CLE19p. (A) No peptide. (B) CLE19p. Note that at this stage the number of ground tissue daughter cells (marked with arrowheads) was not increased further, and no GFP expression was detectable in the pericycle layer. Ground tissue daughter cells are marked with arrowheads. The scale bars represent 30 μm.
