Phenotypes of Ectopic HAN Expression.
(A) Lobed cauline leaf from a 35S:HAN plant. Inset shows a wild-type cauline leaf.
(B) Wild-type inflorescence.
(C) 35S:HAN inflorescence.
(D) Wild-type (left) and 35S:HAN flowers.
(E) Wild-type (right) and 35S:HAN siliques.
(F) to (H) 35S:HAN-GR transformants.
(F) DEX-treated inflorescence has early opening flowers and a short stem.
(G) Seedlings mock-treated from at 11 d of age, shown at 29 d old.
(H) Seedlings treated with DEX beginning at 11 d of age, shown at 29 d old. Arrow points to lobed leaf margins.
(I) Homozygous 35S:HAN-GR seedling germinated on a DEX plate at 9 d.
(J) SAM of 10-d-old wild-type seedling. M, SAM.
(K) and (L) SAMs of 10-d-old 35S:HAN-GR seedlings germinated on DEX plates. Arrows point to the SAMs.
(M) WUS expression in a 10-d-old 35S:HAN-GR seedling germinated on non-DEX plates.
(N) Absence of WUS expression in a 10-d-old 35S:HAN-GR seedling germinated on DEX plates.
(O) Non-DEX-induced control stomata with two guard cells.
(P) and (Q) Guard cells in 10-d-old and 6-d-old DEX-treated 35S:HAN-GR seedlings, respectively. Arrows point to stomata with five or seven guard cells.
(R) Mock-treated 35S:HAN-GR root tip. Arrow points to the root cap.
(S) DEX-induced 35S:HAN-GR root tip.
Bars in (A) to (I) = 1 mm; bars in (J) to (S) = 50 μm (except for [Q], in which the bar = 10 μm).
