Tri-arabinosylation facilitates the bioactivity of CLE3 peptide in Arabidopsis
{{output}}
Post-translational modification is critical for the bioactivity of small secreted-signaling peptides. The shoot apical meristem (SAM) activity that defines SAM size is controlled by the CLAVATA3 (CLV3) peptide ligand, which belongs to the CLV3/EMBRYO SURROUNDI... ...
