1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The transcriptome-wide contributions of Rho-dependent and intrinsic (Rho-independent) transcription termination mechanisms in bacteria are unclear. By sequencing released transcripts in a wild-type strain and strains containing deficiencies in NusA, NusG and/or Rho (10 strains), we produced an atlas of terminators for the model Gram-positive bacterium Bacillus subtilis. We found that NusA and NusG stimulate 77% and 19% of all intrinsic terminators, respectively, and that both proteins participate in Rho-dependent termination. We also show that Rho stimulates termination at 10% of the intrinsic terminators in vivo. We recapitulated Rho-stimulated intrinsic termination at 5 terminators in vitro and found that Rho requires the KOW domain of NusG to stimulate this process at one of these terminators. Computational analyses of our atlas using RNAstructure, MEME suite and DiffLogo, combined with in vitro transcription experiments, revealed that Rho stimulates intrinsic terminators with weak hairpins and/or U-rich tracts by remodelling the RNA upstream of the intrinsic terminator to prevent the formation of RNA structures that could otherwise compete with the terminator hairpin. We also identified 56 putative examples of 'hybrid Rho-dependent termination', wherein classical Rho-dependent termination occurs after readthrough of a Rho-stimulated intrinsic terminator.
