Fig. 2. Patterns of root hair formation in the primary roots of 5-day-old seedlings. (A,H) Wild type, (B) cpc, (C) 35S::CPC, (D,I) gl2-1, (E) 35S::R, (F,J) 35S::RN and (G,K) GL2 promoter::CPC in cpc. Asterisk indicates cell files forming root hairs. (A to G and H to K are of the same magnification. Scale bars in A (for A-G) 200 µm; in H (for H-K) 50 µm.
