Involved in the perception of CLV3 and CLV3-like peptides, that act as extracellular signals regulating meristems maintenance (By similarity). Contributes, with WAKL22/RFO1, to resistance to F.oxysporum (f.) matthioli in cv. Columbia relative to cv. Ty-0 (PubMed:15965251, PubMed:23717215). Expressed at very low levels in the shoot apex. Normal resistance to F.oxysporum (f.) matthioli in cv. Columbia. The double mutant rfo1 rfo2 is strongly susceptible to F.oxysporum. Belongs to the RLP family. Wrong choice of frame.
