Additional file 2:

FIL-response genes that are differentially expressed at 4 h and 8 h following DEX treatment or at 8 h following DEX treatment. This file contains lists of genes that are have been placed into two groups. Group A genes are differentially expressed at 4 h and 8 h following DEX treatment, whereas Group B genes are differentially expressed at 8 h but not 4 h following DEX treatment. (

Histochemical staining of seedlings treated with DEX and CHX. This figure shows the effectiveness of DEX and DEX/CHX treatments on control plants. Histochemical staining for GUS activity in ten-day-old 35SproI> > GUS seedlings exposed to a mock DEX/CHX treatment (A), CHX (B), DEX (C) and DEX/CHX (D) for 9 h. Scale bars are 1 mm.

Vegetative phenotypes associated with steroid-induced activation of abaxially expressed FILand constitutively expressed YAB3. This figure shows the phenotype of FILpro::FIL:GR plants and 35Spro::YAB3:GR plants continuously exposed to DEX. (A) Fourteen-day-old FILpro::FIL:GR plants grown on soil and sprayed with DEX (see Methods). (B,C) 35Spro::YAB3:GR plant grown on media without DEX (B) or in the presence of DEX (C). Scale bars are 1 mm.

Vegetative phenotype associated with continuous FIL activation in different mutants backgrounds. This figure shows the DEX-inducible phenotype and leaf epidermal cell morphology of mutant plants harbouring the 35Spro::FIL:GR construct. (A-D) Twenty-day-old 35Spro::FIL:GR (A), 35Spro::FIL:GR/arf4 (B), 35Spro::FIL:GR/kan1 (C) and 35Spro::FIL:GR/arf4 kan1 (D), plants grown on soil and sprayed with DEX (see Methods). (E-I) SEM of the adaxial surface of a leaf taken from 35Spro::FIL:GR plants (E, F), a 35Spro::FIL:GR/arf4 plant (G), a 35Spro::FIL:GR/kan1 plant (H) or a 35Spro::FIL:GR/arf4 kan1 plant (I). Plants received a mock treatment (E) or were sprayed with DEX (F-I). Scale bars are 2 mm (A-D) and 100 μM (E-I).
