The Transcriptional and Splicing Changes Caused by Hybridization Can Be Globally Recovered by Genome Doubling during Allopolyploidization.

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
Polyploidization is a major driving force in plant evolution. Allopolyploidization, involving hybridization and genome doubling, can cause extensive transcriptome reprogramming which confers allopolyploids higher evolutionary potential than their diploid progenitors. To date, little is known about the interplay between hybridization and genome doubling in transcriptome reprogramming. Here, we performed genome-wide analyses of transcriptome reprogramming during allopolyploidization in wheat and brassica lineages. Our results indicated that hybridization-induced transcriptional and splicing changes of genes can be largely recovered to parental levels by genome doubling in allopolyploids. As transcriptome reprogramming is an important contributor to heterosis, our finding updates a longstanding theory that heterosis in interspecific hybrids can be permanently fixed through genome doubling. Our results also indicated that much of the transcriptome reprogramming in interspecific hybrids was not caused by the merging of two parental genomes, providing novel insights into the mechanisms underlying both heterosis and hybrid speciation.
