Figure 5.

napp-1 and pirp-1 Plants Exhibit Defects in Trichome Development.

(A) Trichomes on 2-week-old wild-type leaves have a uniform shape, generally with three branches.

(B) and (C) Trichomes on 2-week-old leaves of napp-1 (B) and pirp-1 (C) have highly variable shapes, whereas leaf shape is normal.

(D) Stem trichomes of wild-type plants are straight.

(E) and (F) Stem trichomes of napp-1 (E) and pirp-1 (F) plants are shorter and crooked.

Bars = 0.5 mm in (A), (B), and (C) and 1 mm in (D), (E), and (F).
