Rescue of the Dwarf Phenotype of gid2 by Excess GA and GID1.

Gross morphology of transgenic plants grown for 6 weeks with or without GA treatment. Three-week-old regenerated transgenic plants were transferred to soil containing 10⁻⁴ M GA₃ (+) or solvent (−) and grown for further 3 weeks. The symbols for each plant are identical to those in Figure 5. GA₃ − and + of vec gid2-2 were from same transformant line, and GA₃ − and + of GID1-ov gid2-2 were also from same transformant line. The same results were obtained from another three independent vec gid2-2 and GID1-ov gid2-2 lines. Bar = 10 cm.
