Increased accumulation of intron-containing transcripts in rice mitochondria caused by low temperature: is cold-sensitive RNA editing implicated?
Article in Current genetics, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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 increase in the unspliced cox2 transcript and accompanying decrease in the frequency of RNA editing near the exon/intron junction (intron binding site 1, IBS1) have been reported in cold-treated wheat. Here, an attempt was made to clarify whether a similar phenomenon occurs in rice. Levels of unspliced cox2 transcript increased and its editing at the IBS was abolished after cold treatment. The accumulation of COXII protein remained unaffected. The accumulation of intron-containing transcripts of another eight mitochondrial genes, 23 introns in total, was analyzed by Northern blotting and semi-quantitative RT-PCR. An increase in 14 of the 23 intron-adjoining cDNA after cold treatment was observed. Six RNA editing sites in the IBS of four genes were tested as to their status by sequencing cDNA. One of these sites in the nad7 transcript showed a close association with splicing, with editing and splicing occurring simultaneously, irrespective of cold treatment. Two other sites in the intron-containing cox2 and rps3 transcripts were sensitive to cold, where editing frequency began to decrease 1 day after cold treatment, and finally exhibited a tight association with splicing 14 days later. The other sites were efficiently edited. The intron-spliced transcripts were fully edited at all six sites.
