Figure 7.

Leaf Phenotypes of RNAi Plants.

(A) Thick, curled leaves of plants with the mild phenotype, as shown in Figure 1C, grown for 15 d with RNAi induction. Leaves have roughened surfaces.

(B) The youngest leaves developed with reduced γ-tubulin levels have club-shaped blades.

(C) Trichomes with extremely swollen bases that appear with high frequency.

(D) Unbranched trichomes with bulged tips developed on leaves later upon RNAi induction, and the youngest malformed leaves were hairless (B).

Bars = 250 μm.
