Horizontal transfer of DNA from the mitochondrial to the plastid genome and its subsequent evolution in milkweeds (apocynaceae).
Article in Genome biology and evolution, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 92 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
Horizontal gene transfer (HGT) of DNA from the plastid to the nuclear and mitochondrial genomes of higher plants is a common phenomenon; however, plastid genomes (plastomes) are highly conserved and have generally been regarded as impervious to HGT. We sequenced the 158 kb plastome and the 690 kb mitochondrial genome of common milkweed (Asclepias syriaca [Apocynaceae]) and found evidence of intracellular HGT for a 2.4-kb segment of mitochondrial DNA to the rps2-rpoC2 intergenic spacer of the plastome. The transferred region contains an rpl2 pseudogene and is flanked by plastid sequence in the mitochondrial genome, including an rpoC2 pseudogene, which likely provided the mechanism for HGT back to the plastome through double-strand break repair involving homologous recombination. The plastome insertion is restricted to tribe Asclepiadeae of subfamily Asclepiadoideae, whereas the mitochondrial rpoC2 pseudogene is present throughout the subfamily, which confirms that the plastid to mitochondrial HGT event preceded the HGT to the plastome. Although the plastome insertion has been maintained in all lineages of Asclepiadoideae, it shows minimal evidence of transcription in A. syriaca and is likely nonfunctional. Furthermore, we found recent gene conversion of the mitochondrial rpoC2 pseudogene in Asclepias by the plastid gene, which reflects continued interaction of these genomes.
