Extended Data Fig. 2: Strength of maize promoters depends on the TATA box location in maize protoplasts.
From: Synthetic promoter designs enabled by a comprehensive analysis of plant core promoters
a, Histogram showing the percentage of maize promoters with a TATA box at the indicated position (reproduced from Fig. 4). Three peaks in the distribution of TATA boxes are highlighted in grey. Peak 1 spans bases −72 to −65, peak 2 spans bases −59 to −50, and peak 3 spans bases −34 to −24. b, Violin plots, boxplots and significance levels (as defined in Fig. 2) of promoter strength for maize promoters without enhancer in the indicated assay system. Promoters without a TATA box (−) were compared to those with a TATA box outside (+/−) or within one of the three peaks highlighted in (a).
