PolII mapping during the stress response. (a) Heat map view of HSP104 (top panel), an induced gene, or NOP7 (bottom panel), a repressed gene, during a time course of heat shock. (b) Data from (a), but plotted as a graph rather than a heatmap. Data on the y-axis are shown as log(2). Probes annotated as 5', mid, and 3' CDS are indicated below the gene annotation described (5' CDS = first 500 bp of coding sequence, 3' CDS = last 500 bp of coding sequence, mid-CDS = remaining coding sequence [16, 19]). (c) Data from (a, b) were grouped by location as shown in (b). Averaged data for each group is plotted versus time at 37°C. HS, heat shock; Pol2, RNA polymerase II.
