Horizontal Gene Transfer in Five Parasite Plant Species in Orobanchaceae.

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
We sequenced genomes of five parasite species in family Orobanchaceae to explore the evolutionary role of horizontal gene transfer in plants. Orobanche minor and Aeginetia indica are obligate parasites with no photosynthetic activity, whereas the other three (Pedicularis keiskei, Phtheirospermum japonicum, and Melampyrum roseum) are facultative parasites. By using reference genome sequences and/or transcriptomes of 14 species from Fabaceae and Poaceae, their major host families, we detected 106 horizontally transferred genes (HGT genes), only in the genomes of the two obligate parasites (22 and 84 for Oro. minor and Ae. indica, respectively), whereas none in the three facultative parasites. The HGT genes, respectively, account for roughly 0.1% and 0.2% of the coding genes in the two species. We found that almost all HGT genes retained introns at the same locations as their homologs in potential host species, indicating a crucial role of DNA-mediated gene transfer, rather than mRNA mediated retro transfer. Furthermore, some of the HGT genes might have transferred simultaneously because they located very closely in the host reference genome, indicating that the length of transferred DNA could exceed 100 kb. We confirmed that almost all introns are spliced in the current genome of the parasite species, and that about half HGT genes do not have any missense mutations or frameshift-causing indels, suggesting that some HGT genes may be still functional. Evolutionary analyses revealed that the nonsynonymous-synonymous substitution ratio is on average elevated on the lineage leading to HGT genes, due to either relaxation of selection or positive selection.
