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

RNA-directed DNA methylation (RdDM) is an important de novo DNA methylation pathway in plants. Small interfering RNAs (siRNAs) generated by Dicers from RNA polymerase IV (Pol IV) transcripts are thought to guide sequence-specific DNA methylation. To gain insight into the mechanism of RdDM, we performed whole-genome bisulfite sequencing of a collection of Arabidopsis mutants, including plants deficient in Pol IV (nrpd1) or Dicer (dcl1/2/3/4) activity. Unexpectedly, of the RdDM target loci that required Pol IV and/or Pol V, only 16% were fully dependent on Dicer activity. DNA methylation was partly or completely independent of Dicer activity at the remaining Pol IV- and/or Pol V-dependent loci, despite the loss of 24-nt siRNAs. Instead, DNA methylation levels correlated with the accumulation of Pol IV-dependent 25-50 nt RNAs at most loci in Dicer mutant plants. Our results suggest that RdDM in plants is largely guided by a previously unappreciated class of Dicer-independent non-coding RNAs, and that siRNAs are required to maintain DNA methylation at only a subset of loci.
