Effect of the CLE14 polypeptide on homolog gene expression in rice and tomato roots.

The CLAVATA3/ESR (CLE) plant polypeptides act as peptide hormones in various physiological and developmental aspects in a diverse array of land plants. One of the family of genes, , is reported to induce root hair formation in roots. Previously, we demonstrated that the application of synthetic CLE14 polypeptide treatment induced excess root hairs, and reduced the expression level of the non-hair cell fate determinant gene, () in roots.
