Complex organization of the soybean mitochondrial genome: recombination repeats and multiple transcripts at the atpA loci.
Article in Current genetics, 1993. 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
Identification of the soybean mitochondrial atpA open reading frame (atpA ORF) was based on sequence similarity with atpA genes in other plant mitochondria and partial protein sequencing. The atpA reading frame ends with four tandem UGA codons which overlap four tandem AUG codons initiating an unidentified reading frame, orf214. The atpA-orf214 region is found in multiple sequence contexts in soybean mitochondrial DNA (mtDNA), which can be attributed to the presence of two recombination repeats. A 1-kb repeat spans 600 nucleotides (nt) of atpA N-terminal coding region and 400 nt of upstream sequence. Its four configurations correspond to two full-length atpA-orf214 genes and two truncated pseudogenes. A 2-kb repeat lies 3 kb downstream from the 1-kb repeat. Restriction maps of cosmid clones suggest that a 10-kb segment containing both repeats is itself duplicated in the mt genome. With two recombination repeats present in a total of three copies per genome, soybean mtDNA is expected to consist of a complex population of subgenomic molecules. Transcription of the atpA loci was analysed by Northern blotting and S1 nuclease protection. The atpA genes express multiple transcripts with one major 3' end and heterogeneous 5' sequences extending several kb upstream of the atpA coding region. The atpA gene and orf214 are co-transcribed on all major transcripts. The pseudogenes do not express stable RNAs.
