Ribosomal RNA processing and an RNase R family member in chloroplasts of Arabidopsis.
Article in Plant molecular biology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 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
An Arabidopsis mutant rnr1 , which has a defect in the basic genetic system in chloroplasts, was isolated using the screening of the high chlorophyll fluorescence phenotype. Whereas chlorophyll fluorescence and immunoblot studies showed the mutant had reduced activities of photosystems I and II, molecular characterization of the mutant suggested that a T-DNA insertion impaired the expression of a gene encoding a RNase R family member with a targeting signal to chloroplasts. Since RNase R family members have a 3'-5' exoribonuclease activity, we examined the RNA profile in chloroplasts. In rnr1 the intercistronic cleavage between 23S and 4.5S rRNA was impaired, and a significant reduction in rRNA in chloroplasts was found, suggesting that RNR1 functions in the maturation of chloroplast rRNA. The present results suggest that defects in the genetic system in chloroplasts cause high chlorophyll fluorescence, pale green leaf, and marked reduction in the growth rate, whereas the levels of some chloroplast RNA were higher in rnr1 than in the wild-type.
