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 biogenesis and activity of chloroplasts in both vascular plants and algae depends on an intracellular network of nucleus-encoded, trans-acting factors that control almost all aspects of organellar gene expression. Most of these regulatory factors belong to the helical repeat protein superfamily, which includes tetratricopeptide repeat, pentatricopeptide repeat, and the recently identified octotricopeptide repeat (OPR) proteins. Whereas green algae express many different OPR proteins, only a single orthologous OPR protein is encoded in the genomes of most land plants. Here, we report the characterization of the only OPR protein in Arabidopsis thaliana, RAP, which has previously been implicated in plant pathogen defense. Loss of RAP led to a severe defect in processing of chloroplast 16S rRNA resulting in impaired chloroplast translation and photosynthesis. In vitro RNA binding and RNase protection assays revealed that RAP has an intrinsic and specific RNA binding capacity, and the RAP binding site was mapped to the 5' region of the 16S rRNA precursor. Nucleoid localization of RAP was shown by transient green fluorescent protein import assays, implicating the nucleoid as the site of chloroplast rRNA processing. Taken together, our data indicate that the single OPR protein in Arabidopsis is important for a basic process of chloroplast biogenesis.
