Fig. 2. Immunolocalization of HA-tagged CPC in roots of the cpc-1 mutant. (A) Schematic representation of the gene construct with the HA-tag at the N terminus of the CPC-coding region (CPCp::HA:CPC). (B) Root phenotype. (C) Immunostaining of HA:CPC in a root transverse section. Signals in nuclei of hair cells are stronger than those of non-hair cells. Root hair cells are marked by asterisks. Scale bars: 200 µm in B; 50 µm in C.
