(B-C) Comparison of normalized expression levels between wild-type configuration and motif knockouts for two types of core promoters (developmental: CG8157 (B); constitutive: RpL5 (C)). Upper panels: schematic depiction of the wild-type motif compositions (TTGTT motif in RpL5 is ignored due to its strong overlap with R-INR). Two-sample t-test: ns, not significant, *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001; ****p ≤ 0.0001. The middle hinge represents the median. The Interquartile range the difference between the 75th and 25th percentiles. 3-4 biological replicate measurements.
