Symmetric subgenomes and balanced homoeolog expression stabilize the establishment of allopolyploidy in cyprinid fish.
Article in BMC biology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
backgroundInterspecific postzygotic reproduction isolation results from large genetic divergence between the subgenomes of established hybrids. Polyploidization immediately after hybridization may reset patterns of homologous chromosome pairing and ameliorate deleterious genomic incompatibility between the subgenomes of distinct parental species in plants and animals. However, the observation that polyploidy is less common in vertebrates raises the question of which factors restrict its emergence. Here, we perform analyses of the genome, epigenome, and gene expression in the nascent allotetraploid lineage (2.95 Gb) derived from the intergeneric hybridization of female goldfish (Carassius auratus, 1.49 Gb) and male common carp (Cyprinus carpio, 1.42 Gb), to shed light on the changes leading to the stabilization of hybrids.
resultsWe firstly identify the two subgenomes derived from the parental lineages of goldfish and common carp. We find variable unequal homoeologous recombination in somatic and germ cells of the intergeneric F
conclusionsOur results reveal a series of changes in transposable elements, unequal homoeologous recombination, cis- and trans-regulations (e.g. DNA methylation), and homoeologous expression, suggesting their potential roles in mediating adaptive stabilization of regulatory systems of the nascent allotetraploid lineage. The symmetrical subgenomes and homoeologous expression provide a novel way of balancing genetic incompatibilities, providing a new insight into the early stages of allopolyploidization in vertebrate evolution.
