Transgenic and wild-type seeds were germinated on vertical plates, as shown in Figure 2A. These seedlings were grown under either 16 h of light or total darkness with (+) or without (−) GA₃ (10 μm) in the medium. Data are means ± se (n < 30).

^aThe integration of the transgene in line 25-3 resulted in a recessive albino mutation; therefore, hemizygous transgenic plants of line 25-3 were used to generate data for this and the following tables.
