Transcription of atp1 is influenced by both genomic configuration and nuclear background in the highly rearranged mitochondrial genomes of Silene vulgaris.
Article in Plant molecular biology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 extraordinary variation in mitochondrial DNA sequence exists in angiosperm Silene vulgaris. The atp1 gene is flanked by very variable regions, as deduced from four completely sequenced mitochondrial genomes of this species. This diversity contributed to a highly variable transcript profile of this gene observed across S. vulgaris populations. We examined the atp1 transcript in the KOV mitochondrial genome and found three 5' ends, created most likely by the combination of transcription initiation and RNA processing. Most atp1 transcripts terminated about 70 bp upstream of the translation stop codon, which was present in only 10 % of them. Controlled crosses between a KOV mother and a geographically distant pollen donor (Krasnoyarsk, Russia) showed that nuclear background also affected atp1 transcription. The distant pollen donor introduced the factor(s) preventing the formation of a long 2,100 nt-transcript, because this long atp1 transcript reappeared in the progeny from self-crosses. The highly rearranged mitochondrial genomes with a variation in gene flanking regions make S. vulgaris an excellent model for the study of mitochondrial gene expression in plants.
