Nonadditive expression of homoeologous genes is established upon polyploidization in hexaploid wheat.
Article in Genetics, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 59 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
Effects of polyploidy in allohexaploid wheat (Triticum aestivum L.) have primarily been ascribed to increases in coding sequence variation and potential to acquire new gene functions through mutation of redundant loci. However, regulatory variation that arises through new promoter and transcription factor combinations or epigenetic events may also contribute to the effects of polyploidization. In this study, gene expression was characterized in a synthetic T. aestivum line and the T. turgidum and Aegilops tauschii parents to establish a timeline for such regulatory changes and estimate the frequency of nonadditive expression of homoeologous transcripts in newly formed T. aestivum. Large-scale analysis of nonadditive gene expression was assayed by microarray expression experiments, where synthetic T. aestivum gene expression was compared to additive model values (mid-parent) calculated from parental T. turgidum and Ae. tauschii expression levels. Approximately 16% of genes were estimated to display nonadditive expression in synthetic T. aestivum. A certain fraction of the genes (2.9%) showed overdominance or underdominance. cDNA-single strand conformation polymorphism analysis was applied to measure expression of homoeologous transcripts and further verify microarray data. The results demonstrate that allopolyploidization, per se, results in rapid initiation of differential expression of homoeologous loci and nonadditive gene expression in T. aestivum.
