Fig. 2. Phenotypes associated with CPC-homolog gain- and loss-of-function mutants. (A-L) Root hair formation of a 5-day-old Arabidopsis seedling showing no root hair phenotype (G,H), reduced number of root hairs (B,C) and increased number of root hairs (I-L). (M-X) Trichome formation on the 2-week-old third leaves showing increased number of trichomes (N-T). No trichome formation was observed in gain-of-function plants (U-X). Scale bars: 100 µm in A for A-L; 1 mm in M-X.
