Secreted peptides are now recognized as important members of hormones that coordinate and specify cellular functions in plants. Recent accumulating evidence shows that secreted peptide hormones are often post-translationally modified, and such modification is critical for their function. In this review, we highlight hydroxyproline arabinosylation, which has been found in several peptide hormones including CLAVATA3 (CLV3), a key peptide controlling stem cell renewal and differentiation in Arabidopsis shoot apical meristem. Arabinosylation of CLV3 is important for its biological activity and for high-affinity binding to its receptor, CLV1. We discuss the physiological functions of known glycopeptide hormones, the structural information on sugar chains, and possible mechanisms of glycosylation.
