Figure 6.

dps1 enhances RTBV promoter activity from an upstream position. Constructs used for transfection of O.sativa protoplasts are shown on the left. The filled box indicates dps1 (+50 to +90). Dotted boxes depict deletions of dps1. The dotted line represents deletion of dps3 (+8 to +50). A bent arrow indicates the transcription start site. All constructs were tested in at least three independent transfections. For each construct the mean promoter activity is indicated as a percentage of the activity of the wild-type construct R-218 (set as 100%).
