Peptides Regulating Apical Meristem Development
Small signaling peptides are involved in numerous aspects of plant development. A well-studied group of peptides is the CLE family with its most prominent member CLAVATA 3 (CLV3), a key regulator of apical meristem maintenance during growth and development. Members of the CLE peptide family share a high sequence similarity, but are capable of triggering independent pathways. Recent work has revealed complex networks of interacting receptors that recognize different peptides, as well as various posttranslational modifications of the peptides which could account for the signaling specificities within the family. With the CLV pathway well studied in Arabidopsis, the insight gained in this model plant can now be transferred to other plant species to control meristem development.
