(A) Scatterplot depicting the expression measurements with ecdysone induction versus measurements without ecdysone for all tested promoters separated by promoter architecture (Fig EV3). Each color represents one architecture (color-code indicated in the insert). Three types of line are used to indicate the expression fold change with no increase (y = x; solid line), 2-fold increase (y = x + 1; dotted line) and 4-fold increase (y = x + 2; dashed line). Red vertical dashed line: log2 basal expressions = 2. Log2 expressions > 2 on the right of the red dotted line.
