Regulation of the Expression of WD-repeat/bHLH/MYB Complex by Gibberellin. (A) Real-time PCR analysis for GL1, GL3, EGL3 and TTG1 in Col-0 wild-type treated without (Mock) or with Gibberellin (GA). ACTIN8 was used as the internal control. Error bars represent SE. (B) Real-time PCR analysis for GL1, GL3, EGL3 and TTG1 in the Landsberg erecta (Ler) wild-type, ga1-3, Q1 (ga1-3 gai-t6 rgl1-1 rgl2-1, wild-type for RGA and RGL3), Q3 (ga1-3 gai-t6 rgl1-1 rga-t2, wild-type for RGL2 and RGL3), penta (ga1-3 gai-t6 rga-t2 rgl1-1 rgl2-1, wild-type for RGL3) and della (gai-t6 rga-t2 rgl1-1 rgl2-1 rgl3-1) plants grown on MS medium. ACTIN8 was used as the internal control. Error bars represent SE.
