Synthesis and processing of tRNA-related SINE transcripts in Arabidopsis thaliana.
Article in Nucleic acids research, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Despite the ubiquitous distribution of tRNA-related short interspersed elements (SINEs) in eukaryotic species, very little is known about the synthesis and processing of their RNAs. In this work, we have characterized in detail the different RNA populations resulting from the expression of a tRNA-related SINE S1 founder copy in Arabidopsis thaliana. The main population is composed of poly(A)-ending (pa) SINE RNAs, while two minor populations correspond to full-length (fl) or poly(A) minus [small cytoplasmic (sc)] SINE RNAs. Part of the poly(A) minus RNAs is modified by 3'-terminal addition of C or CA nucleotides. All three RNA populations accumulate in the cytoplasm. Using a mutagenesis approach, we show that the poly(A) region and the 3' end unique region, present at the founder locus, are both important for the maturation and the steady-state accumulation of the different S1 RNA populations. The observation that primary SINE transcripts can be post-transcriptionally processed in vivo into a poly(A)-ending species introduces the possibility that this paRNA is used as a retroposition intermediate.
