A pangenome of tetraploid wheat reveals the genetic architecture underlying domestication and genomic diversity for breeding.
Article in Nature genetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Tetraploid wheat (Triticum turgidum L., BBAA), a key pasta crop, serves as an untapped genetic resource with rich genomic diversity for hexaploid bread wheat improvement. Here we de novo assembled 12 genomes spanning all 10 recognized tetraploid wheat (genome BBAA) subspecies, and a graph-based pangenome was constructed. Chromosome rearrangements drove subgenome asymmetry and shaped genomic divergence, with an average of 0.25 million structural variations per accession, predominantly attributable to transposon activity. Using 736 globally distributed tetraploid wheat accessions, we identified locally adapted subgroups with untapped breeding potential and discovered a novel retrotransposon‑induced loss‑of‑function Btr1-A allele responsible for convergent adaptation of non-brittle rachis. Genome-wide association studies identified 287 loci associated with 32 traits. A homeodomain-leucine zipper transcription factor HAT14-B that enhances both spikelet number and grain size was identified. This subspecies-wide pangenome enriches Triticeae AB subgenome resources and facilitates the discovery and application of agronomically important genetic variations.
