Transcriptome shock invokes disruption of parental expression-conserved genes in tetraploid wheat.

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
Allopolyploidy often triggers phenotypic novelty and gene expression remolding in the resulting polyploids. In this study, we employed multiple phenotypic and genetic approaches to investigate the nature and consequences of allotetraploidization between A- and S-subgenome of tetraploid wheat. Results showed that karyotype of the nascent allopolyploid plants (AT2) is stable but they showed clear novelty in multiple morphological traits which might have positively contributed to the initial establishment of the tetraploids. Further microarray-based transcriptome profiling and gene-specific cDNA-pyrosequencing have documented that transcriptome shock was exceptionally strong in AT2, but a substantial proportion of the induced expression changes was rapidly stabilized in early generations. Meanwhile, both additive and nonadditive expression genes showed extensive homeolog expression remodeling and which have led to the subgenome expression dominance in leaf and young inflorescence of AT2. Through comparing the homeolog-expressing patterns between synthetic and natural tetraploid wheats, it appears that the shock-induced expression changes at both the total expression level and subgenome homeolog partitioning are evolutionarily persistent. Together, our study shed new light on how gene expression changes have rapidly occurred at the initial stage following allotetraploidization, as well as their evolutionary relevance, which may have implications for wheat improvements.
