    Detection of discrete Rut peaks along the M. tuberculosis genome. ( A ) Representative R 10 /R 0 enrichment profiles obtained with FL Mtb Rho (mean traces; Log 10 scale) along both strands of the H37Rv genome. Positive values are in dark blue while negative values are in red. Blue asterisks mark significant Rut peaks detected with PEAKachu (Benjamini–Hochberg adjusted P -value <.05). Pink symbols locate 3′-end positions identified by Term-seq and attributed to high-confidence RDTT events . ( B ) Venn diagram of significant Rut peaks obtained with FL Mtb Rho or ΔNID- Mtb Rho. ( C ) Motifs enriched in FL- Rut (E-value = 3.5 × 10 −5 and 1.6 × 10 −4 for motifs 1 and 2, respectively) and ΔNID- Rut (E-value = 4.4 × 10 −2 ) peaks as determined by differential MEME analysis (see the Supplementary data). The MEME motif enriched in Rut peaks in <t>E.</t> <t>coli</t> is shown for comparison. This motif reflects RNA binding preferences per Ec Rho subunit while both the length and sequence of inter-subunit RNA linkers are much less constrained [ , ]. Percentages correspond to the number of MEME cases with respect to total number of Rut peaks. The gray boxes locate the position of the 5′YC-binding (Y = U or C) PBS pocket of E. coli ’s Rho.

    Localization of Rut sites in M. tuberculosis . ( A ) Categories of Rut peaks (blue arrows) and their respective proportions, comparing data from this work (FL- Rut peaks only) to H-SELEX analyses of RDTT in E. coli  and B. subtilis . ( B – D ) Examples of Rut peaks found in 5′UTRs and potentially involved in conditional RDTT. ( E ) Probability plot of the shortest distances between transcript 3′-ends determined by Term-seq  and the FL- Rut peaks. The reference point (0) corresponds to the downstream edge of the nearest Rut peak, as depicted in the diagram above the graph. Under ideal conditions, the 3′ends of RDTT transcripts are expected to localize downstream (d > 0) of the Rut site. However, in vivo 3′-to-5′ exonucleolytic trimming—sometimes extending beyond the Rut site (d < 0)—can occur until blocked by a sufficiently stable RNA structure (see diagram above graph). The red curve represents the analysis using only the subset of transcript 3′-ends assigned to RDTT with high-confidence in previous work , while the black curve includes all transcript 3′-ends.
