Whirly1 in chloroplasts associates with intron containing RNAs and rarely co-localizes with nucleoids.

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.
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 nucleic acid binding protein Whirly1 of barley has been located to both chloroplasts and the nucleus of the same cell. Immunogold labelling furthermore showed that in vivo Whirly1 does not strictly co-localize with DNA in chloroplasts, while it is closely associated with DNA in the nucleus. High-resolution imaging of Whirly1-GFP and PEND-RFP fusion proteins revealed that only a minor part of Whirly1 co-localizes with nucleoids. The co-localization with nucleoids is in accordance with the detection of Whirly1 in a conventionally prepared fraction of the transcriptionally active chromosome (TAC). By further purification and enrichment of transcriptional activity Whirly1, however, was lost from the TAC fraction. Knockdown of Whirly1 in transgenic barley plants had neither impact on transcription of selected protein coding genes nor on genes coding for ribosomal RNAs or tRNAs. The results of RIP-chip experiments showed that barley Whirly1 as its maize orthologue associates with a set of intron containing plastid RNAs. Taken together, the results suggest that plastid-located Whirly1 functions primarily in RNA metabolism rather than as a DNA binding protein.
