Fig. 2. Inflorescence trichome initiation in response to gibberellins in
wild-type Arabidopsis plants and GIS clade mutants. (A)
Trichome initiation on inflorescence organs of GA-deficient ga1-3
mutants treated with increasing concentrations of GA3. (*) Sepal
trichome values represent the total number of trichomes for 12 flowers.
(B) Differential response of GIS clade loss-of-function mutants to GA
applications at increasing concentrations. Values represent averages and
standard errors for 20 plants. WT, wild type.
