Figure 4From: The sequence flanking the N-terminus of the CLV3 peptide is critical for its cleavage and activity in stem cell regulation in ArabidopsisIn vitro root assays of CLV3 peptides with N-terminal extensions. Average root lengths of 8-d-old Ler seedlings (n = 8) after incubations on media containing CLV3 peptides with different N-terminal extensions. Error bar = ± SD. Aligned sequences of all peptides are shown. The Ala substitution in the LHEEA-CLV3p17 is highlighted in red. Average root lengths with significant differences from the non-treated one (P < 0.01 by Student’s t-test) are marked with asterisks.Back to article page
