    CAPRICE (CPC) is a R3-type MYB transcription factor, which induces root-hair cell differentiation in Arabidopsis thaliana. The CPC homologous gene ENHANCER TRY AND CPC1 (ETC1) has a similar function to CPC, and acts in concert with CPC. The CPC protein moves between root epidermal cells, from hairless cells to the neighboring cells, and promotes root-hair differentiation. Therefore, ETC1 is predicted to have movement ability similar to that of CPC. In this study, we generated ETC1:ETC1:GFP and CPC:ETC1:GFP transgenic plants to clarify whether ETC1 exhibits cell-to-cell movement. Transgenic plants showed many-root-haired and trichome-less phenotypes, similar to those observed in CPC:CPC:GFP plants, suggesting a similar function of ETC1 and CPC. However, the ETC1:GFP fusion protein located exclusively to the hairless cells in both ETC1:ETC1:GFP and CPC:ETC1:GFP transgenic plants. These results indicate that, unexpectedly, the ETC1 protein cannot move in the root epidermis from hairless cells to the neighboring cells.
