Experimental details: Figure 6 Upregulated Transcripts Show Evidence of Reduced Nuclear Decay (A) Sequence reads across TYE7 and CTH1 .The top three tracks show changes in total RNA. Note the different scales. The next nine tracks show the binding profiles of Pol II, Nab3, and Mtr4 across the RNA as determined by CRAC. The bottom two tracks map the deletions (the putative site of crosslinking) from reads derived from Nab3 CRAC. The annotated TSS for both genes is marked by a black dotted line, and the red dotted line marks the putative TSS following nutrient downshift. (B) Bar graph comparing the relative abundance of wild-type (WT) TYE7 or CTH1 to mutant (mut) transcripts in which the Nab3 binding site has been removed. Transcript levels were measured by qRT-PCR and normalized to scR1. The values are averages, and error bars are SD (n = 3). (C) Schematic showing the Nrd1 depletion construct.
