Fig. 2. The lue1 mutant exhibits altered cell elongation in response to GA. (A,B) GA treatment promotes flowering in lue1. (A) 35-day-old lue1 mutants control or sprayed with 10 µM GA₃ or GA₄ every 4 days. (B) Flowering time of WT and lue1 plants control or sprayed with 10 µM GA₃ every 4 days until bolting. (C) WT and lue1 leaf elongation upon GA₃ treatment. Petiole and blade measurements were performed on adult plants by selecting the longest leaf of control or GA₃-treated WT and lue1 plants (n minimum=30).
