OsCSLD1, a cellulose synthase-like D1 gene, is required for root hair morphogenesis in rice. by Kim, C, Park, S, Je, B, Park, S, Park, S, Piao, H, Eun, M, Dolan, L, Han, C

“…Given that the Arabidopsis (Arabidopsis thaliana) gene KOJAK/AtCSLD3 is required for root hair elongation and is expressed in the root hair, it appears that OsCSLD1 may be the functional ortholog of KOJAK/AtCSLD3 and that these two genes represent the root hair-specific members of this family of proteins. …”

Building a hair: tip growth in Arabidopsis thaliana root hairs. by Carol, R, Dolan, L

“…Actin has been visualized in vivo in Arabidopsis root hairs by using a green-fluorescent-protein-talin reporter and shown to form a dense mesh in the apex of the growing tip. The kojak gene, which encodes a protein similar to the catalytic subunit of cellulose synthase, is needed in the first stages of hair growth. …”
