- CLE11/12/13 peptides and CIK1/4 receptor kinases regulate columella root cap formation in Arabidopsis.
- Mutations in CLE11/12/13 or CIK1/4 result in reduced columella cell layers and decreased columella stem cell (CSC) division activity.
- CLE11/12/13 treatment enhances phosphorylation levels of CIK1/4, indicating a direct signaling interaction.
- The CLE11/12/13-CIK1/4 module acts upstream of FEZ to promote CSC division and root cap morphogenesis.
- This study expands understanding of peptide-receptor kinase signaling in plant development.
