Abstract

RALFs are secreted peptides that are perceived by various CrRLK1L-LRE/LLG receptor complexes. The mechanistic basis of this perception has now been elucidated showing that the co-receptor LLG binds RALF23 to nucleate a FER receptor complex. This interaction likely occurs in other tissues where RALFs meet CrRLK1L receptors and LRE/LLG co-receptors.

Keywords: Catharanthus roseus RLK1-like (CrRLK1L) receptors; RAPID ALKALINIZATION FACTOR (RALF); glycosylphosphatidylinositol-anchored protein (GPI-AP); peptide signaling.
