GA-Related Phenotypes in pps-1.

(A) Plant height of 1-week-old wild type (WT) and pps-1 germinated on medium containing GA₃ or uniconazole.

(B) Relative length of midrib in the wild type and pps-1 germinated on medium containing GA₃ or uniconazole. The values are shown as mean ± sd (n = 5).

(C) Relative length of midrib in third and fourth leaves of the wild type and d18-dy.

(D) Contents of GA₅₃, GA₄₄, GA₁₉, GA₂₀, and GA₁ in 3-week-old wild-type and pps-1 seedlings.

(E) Real-time PCR analysis of GA metabolic gene expression in fourth leaves of the wild type and pps-1. Data represent mean ± sd in (A) to (C) (n = 5) and in (D) and (E) (n = 3).
