Combined effects of dosage compensation and incomplete dominance on gene expression in triploid cyprinids.
Article in DNA research : an international journal for rapid publication of reports on genes and genomes, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Hybridization and polyploidy are pervasive evolutionary features of flowering plants and frequent among some animal groups, such as fish. These processes always lead to novel genotypes and various phenotypes, including growth heterosis. However, its genetic basis in lower vertebrate is still poorly understood. Here, we conducted transcriptome-level analyses of the allopolyploid complex of Carassius auratus red var. (R) (♀) × Cyprinus carpio L. (C) (♂), including the allodiploid and allotetraploid with symmetric subgenomes, and the two allotriploids with asymmetric subgenomes. The gradual changes of gene silencing and novel gene expression suggested the weakening of the constraint of polymorphic expression in genotypic changes. Then, analyses of the direction and magnitude of homoeolog expression exhibited various asymmetric expression patterns, which supported that R incomplete dominance and dosage compensation were co-regulated in the two triploids. Under these effects, various magnitudes of R-homoeolog expression bias were observed in growth-regulated genes, suggesting that they might contribute to growth heterosis in the two triploids. The determination of R incomplete dominance and dosage compensation, which might be led by asymmetric subgenomes and multiple sets of homologous chromosomes, explained why various expression patterns were shaped and their potential contribution to growth heterosis in the two triploids.
