GL1, GL3, GIS, and GIS2 are indirect targets of RGA. Time course of GL1 (A), GL3 (B), GIS (C), and GIS2 (D) expression in DEX-treated 35S:RGA-GR ga1-3 rga-t2 rgl2 plants and in mock-treated plants (Cont.). All plants were treated with the protein synthesis inhibitor cycloheximide before DEX applications. Transcript levels were measured in young developing inflorescence by real-time PCR 4 and 6 h after treatment. Values represent the average and sd from three measurements and are relative to the expression of the UBQ10 gene.
