The UTRs of affected genes are longer than predicted by genome-wide averages. (A) The average 5′ and 3′ UTR lengths of affected genes in each desMAP were compared with genome-wide average UTR lengths. (B) The length of the dsRNA used to deplete each exosome subunit was plotted opposite the number of decreased transcripts in each desMAP. The distribution of 5′ (C) and 3′ (D) UTR lengths in all desMAPs, left y-axes, plotted opposite the transcriptome-wide distribution of UTR lengths, right y-axes. The 5′ and 3′ UTR length profiles of transcripts increased in the desMAPs of (E,F) Rrp4 and (G,H) Rrp6 with axes as established above.
