Profiling the transcriptional regulatory network reveals putative shared regulatory elements within homoeologs in polyploid Brassica napus.
Article in Genome biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundRegulatory elements and their interactions underpin transciptional control and are essential for plant growth and development. Yet, in the allopolyploid crop Brassica napus, the global regulatory landscape and the architecture of its complex regulatory networks remain elusive.
resultsHere we integrate chromatin accessibility and DNA methylation profiles from four representative accessions to generate a comprehensive atlas of 38,068 regulatory elements in Brassica napus. By coupling these regulatory features with expression quantitative trait locus data, we construct a genome-wide regulatory network comprising 24,541 regulatory elements and 791,512 associations between regulatory elements and genes during seed development. Incorporating 3D genome data reveals that spatial proximity promotes co-expression of cross-chromosomal homoeologous gene pairs through putative shared regulatory elements. Moreover, we uncover pronounced subgenome asymmetry, with the regulatory elements on the An subgenome exerting a disproportionately stronger regulatory influence than those on the Cn subgenome.
conclusionsThis study provides valuable resources for studying the intricate regulatory network governed by regulatory elements and sheds new light on exploring the cross-chromosomal regulation in polyploid plants.
