Table 1. Distribution of total Pol II or its phosphorylated forms in RNAi COMPASS subunit-knockdown lines.
| Gene | Pol II1 | % 5′-end | % 3′-end | p-value (5′ vs 3′) |
| WRKY70 | total | 85±7 | 55±8 | 0.01 |
| Ser5P | 75±7 | - | ||
| Ser2P | - | 39±2 | <0.01 | |
| LTP7 | total | 64±7 | 48±4 | 0.05 |
| Ser5P | 77±3 | - | ||

The average of the ChIP-PCR values ± SD, n = 4, for wdr5R1, wdr5R2, ash2R7, and ash2R16 RNAi knockdown lines, as a percent of wild type. The 5′ and 3′-end regions correspond to regions 2 and 6 in Figure 2; for the shorter LTP7 gene the 3′ end corresponds to region 3. P-values are for the significance of the differences between the 5′-end and 3′-ends.
