Plant mitochondrial rps2 genes code for proteins with a C-terminal extension that is processed.
Article in Plant molecular biology, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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
A gene (rps2) coding for ribosomal protein S2 (RPS2) is present in the mitochondrial (mt) genome of several monocot plants, but absent from the mtDNA of dicots. Confirming that in dicot plants the corresponding gene has been transferred to the nucleus, a corresponding Arabidopsis thaliana nuclear gene was identified that codes for mitochondrial RPS2. As several yeast and mammalian genes coding for mt ribosomal proteins, the Arabidopsis RPS2 apparently has no N-terminal targeting sequence. In the maize mt genome, two rps2 genes were identified and both are transcribed, although at different levels. As in wheat and rice, the maize genes code for proteins with long C-terminal extensions, as compared to their bacterial counterparts. These extensions are not conserved in sequence. Using specific antibodies against one of the maize proteins we found that a large protein precursor is indeed synthesized, but it is apparently processed to give the mature RPS2 protein which is associated with the mitochondrial ribosome.
