Figure 1.

Growth responses of the wild type (D), the d^x mutant, and the 35S∷D line (a d^x-complementing line) under light/dark conditions in the presence or absence of BL. (A) Group of four light-grown seedlings (16 h/day) of D, d^x, and 35S∷D. In each group, the two on the left were grown on media only and the two on the right were grown on media containing 10⁻⁶ M brassinolide. (B) Same as A, but dark-grown. (C) Representative phenotypes of 2-month-old light-grown (16 h/day) plants of each line before BR analysis.
