Overexpression of RD20 modified the expression of the transcription factor LFY but not JA contents. A, Quantitative PCR analysis of gene expression involved in signaling (LFY), biosynthesis (Ga3ox1, GA20ox1, and Ga20ox8), and metabolization (Ga2ox1 and Ga2ox2) of GAs. Plants were harvested at the bolting time of RD20-overexpressing lines. Data represent means and se of three replicates. B, Analysis by liquid chromatography-mass spectrometry of JA contents of lines overexpressing RD20 and control plants. Data are means ± se of triplicate assays. Transgenic plants did not significantly differ from control plants when analyzed by Student’s t test, with P = 0.66 for RD20-OE1 versus control and P = 0.57 for RD20-OE2 versus control. fw, Fresh weight.
