Sequence specificity of CLE peptide activity. Root length of Medicago truncatula plants at 6 days after treatment with different peptides. Control plates did not contain peptide, peptide 1 (SKRKVPSCPDPLHN) and peptide 2 (SKRRVPNGPDPIHN) resemble the CLE motif, peptide 3 (randomized version of peptide 1, DHKSKPPVLRPNSC) and peptide 4 (randomized version of peptide 2, PVHPKGNRNDISPR) do not resemble the CLE motif. Bars with different letters differ significantly at p < 0.0001 (N = 27; one-way ANOVA). Both CLE peptides are significantly different from the no-peptide control and the control peptides with randomized amino acid sequence.
