Expression of the GH3:uidA Reporter Gene in ago1-3 Seedlings.

(A) and (B) GH3:uidA expression in wild-type (A) and ago1-3 (B) seedlings geminated and grown in the light for 8 d in the absence or presence of 1 μM 1-NAA. Bars = 2 mm.

(C) and (D) GH3:uidA expression in wild-type (C) and ago1-3 (D) seedlings that were etiolated for 2.5 d in the dark before transfer to the light for 44 h. Seedlings were then transferred to liquid culture medium without or with 10 μM 1-NAA for 4 h in the same growth conditions. GUS staining was overnight. From left to right in each panel: three nontreated seedling and three seedlings treated with NAA. Bars = 6 mm.
