ABSTRACT
A novel candidate ligand-receptor system, INFLORESCENCE DEFICIENT IN ABSCISSION (IDA) and the related receptor-like kinases (RLKs) HAESA (HAE) and HAESA-LIKE (HSL)2, has been shown to control floral abscission in Arabidopsis thaliana. Furthermore, several IDA-LIKE (IDL) proteins, which contain a conserved C-terminal domain resembling that of the CLAVATA (CLV)3-ENDOSPERM SURROUNDING REGION (ESR)-RELATED (CLE) protein family, have been shown to be partially redundant with IDA. Here, we use the genetic similarities between the IDA and CLV3 signalling systems to hypothesize that closely related peptide ligands are likely to interact with families of closely related RLKs. Guided by this hypothesis and with the aid of genetics and novel methods, ligand-receptor systems can be identified to improve our understanding of developmental processes in plants.
