Figure 4.

Lack of correlation between the number of E2F binding sites and transcriptional activation in E2Fa-DPa^OE plants. The fold induction level of the putative E2F target genes was plotted against the number of E2F elements found in their promoter. Only populations with more than five genes were plotted. The horizontal lines in the box denote the 25th, 50th, and 75th percentile values. The error bars indicate the 5th and 95th percentile values. The square symbol in the box corresponds to the mean of the column of data.
