Maintenance of plastid RNA editing activities independently of their target sites.
Article in EMBO reports, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
RNA editing in plant organelles is mediated by site-specific, nuclear-encoded factors. Previous data suggested that the maintenance of these factors depends on the presence of their rapidly evolving cognate sites. The surprising ability of allotetraploid Nicotiana tabacum (tobacco) to edit a foreign site in the chloroplast ndhA messenger RNA was thought to be inherited from its diploid male ancestor, Nicotiana tomentosiformis. Here, we show that the same ndhA editing activity is also present in Nicotiana sylvestris, which is the female diploid progenitor of tobacco and which lacks the ndhA site. Hence, heterologous editing is not simply a result of tobacco's allopolyploid genome organization. Analyses of other editing sites after sexual or somatic transfer between land plants showed that heterologous editing occurs at a surprisingly high frequency. This suggests that the corresponding editing activities are conserved despite the absence of their target sites, potentially because they serve other functions in the plant cell.
