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

Plants produce a diverse array of small RNA molecules capable of gene regulation, including Pol IV-dependent short interfering (p4-si)RNAs that trigger transcriptional gene silencing. Small RNA transcriptomes are available for many plant species, but mutations affecting the synthesis of Pol IV-dependent siRNAs are characterized only in Arabidopsis and maize, leading to assumptions regarding nature of p4-siRNAs in all other species. We have identified a mutation in the largest subunit of Pol IV, NRPD1, that impacts Pol IV activity in Brassica rapa, an agriculturally important relative of the reference plant Arabidopsis. Using this mutation we characterized the Pol IV-dependent and Pol IV-independent small RNA populations in B. rapa. In addition, our analysis demonstrates reduced production of p4-siRNAs in B. rapa relative to Arabidopsis. B. rapa genomic regions are less likely to generate p4-siRNAs than Arabidopsis but more likely to generate Pol IV-independent siRNAs, including 24 nt RNAs mapping to transposable elements. These observations underscore the diversity of small RNAs produced by plants and highlight the importance of genetic studies during small RNA analysis.
