Fig. 2.

Phenotypic characterizations of WT and transgenic plants. One-month-old WT and transgenic plants grown in vitro are pictured. The top and bottom panels show the same plants with leaves and defoliated, respectively. The transgenic plants were significantly affected in terms of internode elongation. Bar=10cm in the top panel and 5cm in the bottom panel. WT, wild-type; 35:G20, 35S::PtGA20ox transgenic plants; 35:G2, 35S::PtGA2ox1 transgenic plants; T:G20, TobRB7::PtGA20ox transgenic plants; T:G2, TobRB7::PtGA2ox1 transgenic plants; L:G20, LMX5::PtGA20ox transgenic plants; L:G2, LMX5::PtGA2ox1 transgenic plants; GAI, 35S::PtGAI transgenic plants.
