PRE6 is a transcriptional repressor. (A) Subcellular localization of PRE6. GFP fluorescence in the root tips of 7-day-old 35S:GFP-PRE6 transgenic seedlings were observed and photographed under a fluorescence microscopy. Left, GFP channel; middle, bright field; right, merged image. (B) PRE6 is a transcriptional repressor. Plasmids of the effector LD-VP and GD-PRE6 or GD alone as a control, and the reporter LexA:Gal4:GUS (diagrammed on the top) plasmids were co-transfected into protoplasts isolated from rosette leaves of 3 to 4-week-old Col wild type plants, the protoplasts were incubated for 20–22 h at room temperature in darkness, and GUS activity was measured. Data represent the mean ± SD of three replicates. Significantly different from the GD control (p < 0.01).
