Expression of A. thaliana genes for the four promoter classes.
| Gene sets | All genes | Only TATA-box | Only TC[-39,-26]-PLMs | Only TATAΔ-PLMs | [-39,-26]-PLM-less |
|---|---|---|---|---|---|
| HE | 39.2% | 53.8% (< 1e-30) | 36.7% (NS) | 38.1% (NS) | 34.5% (1e-22) |
| LE | 60.8% | 46.2% (2e-24) | 63.3% (NS) | 61.9% (NS) | 65.5% (< 1e-30) |
| SR | 40.4% | 41% (NS) | 44.1% (< 1e-30) | 37.4% (< 1e-30) | 40.2% (NS) |
| WR | 11.1% | 10.3% (NS) | 9.3% (NS) | 13.2% (< 1e-30) | 11.2% (NS) |
| WR-HE+ | 2.2% | 2.4% (NS) | 1.6% (NS) | 2.2% (NS) | 2.3% (NS) |
| WR-LE+ | 3.4% | 2.5% (NS) | 3.1% (NS) | 4.0% (NS) | 3.8% (NS) |
| SR-HE+ | 5.5% | 8.5% (1e-5) | 5.3% (NS) | 5.3% (NS) | 4.6% (8e-6) |
| SR-LE+ | 7.4% | 5% (< 1e-30) | 8.6% (NS) | 6.8% (NS) | 8.1% (< 1e-30) |
The 8 expression categories are described in the Figure 7. HE, High Expression; LE, Low Expression; SR Small Range of expression; WR, Wide Range of expression; HE+ Highest Expressions; LE+, Lowest Expressions. The whole gene set contains the 11161 genes for which we have both a known TSS and CATMA-expression data. We performed two one-sided Fisher exact tests allowing the identification of higher (bold) or lower (underlined) percentages in a gene set in comparison with all other genes, i.e. genes within the whole gene set minus genes within the considered gene set. NS indicates non-significant difference. P-values in parenthesis are less than 5% with the Bonferroni correction.
