Model for CLV1 signaling. CLV3 is processed by a serine protease to create the active ligand (Ito et al., 2006; Ni et al., 2010). Mature CLV3 binds to CLV1, BAM and CLV2 receptors. The CLV1 and CLV2 complexes may interact with each other. Receptor activation leads to repression of POL/PLL1, which are positive regulators of WUS transcription.
