High-resolution genome and genetic map of tetraploid Allium porrum expose pericentromeric recombination.
Article in The plant genome, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
We present the first reference genome of the highly heterozygous autotetraploid Allium porrum (leek). Combining long-read sequencing with single-nucleotide polymorphism (SNP)-array screening of two experimental F1 populations, we generated a genetic map with 11,429 SNP markers across eight linkage groups and a chromosome-scale assembly of A. porrum (leek) totaling 15.2 Gbp in size. The high quality of the reference genome is substantiated by 97.2% BUSCO completeness and a mapping rate of 96% for full-length transcripts. The linkage map exposes the recombination landscape of leek and confirms that crossovers are predominantly proximal, located to the centromeres, contrasting with distal recombination landscapes observed in other Allium species. Comparative genomics reveals structural rearrangements between A. porrum and its relatives (Allium fistulosum, Allium sativum, and Allium cepa), suggesting a closer genomic relationship to A. sativum. Our annotated high-quality reference genome delivers crucial insights into the leek genome structure, recombination landscape, and evolutionary relationships within the Allium genus, with implications for species compatibility in breeding programs, facilitating marker-assisted selection and genetic improvement in leek.
