The results suggest that flax morphotype divergence is driven primarily by selection on pre-existing allelic variation within a conserved gene repertoire, highlighting the importance of standing genetic variation as a key resource for flax breeding and improvement.
A pangenome of tetraploid wheat constructed from 12 de novo genome assemblies spanning all 10 recognized tetraploid wheat subspecies, integrating with whole-genome sequencing data, highlights genetic variation associated with agricultural traits.
Pangenome analyses of chromosome-scale genome assemblies for 125 diverse cucumber accessions highlight structural variation shaped by selection for geographical adaptation, fruit-length diversification and disease resistance, providing a genomic toolkit for cucumber evolution research and precision breeding.

Incipient reproductive isolation in the presence of gene flow has traditionally been attributed to a small number of major-effect loci under strong selection. Here, using the Heliconius erato adaptive radiation, we apply a pangenome framework to examine how mutational divergence, regulatory variation, and structural va...

The genomic resources developed here provide a high-resolution variation map to delineate the genes underpinning yield and developmental traits in groundnut, improved the understanding of the genetic basis of important agronomic traits, and provide a valuable resource for further functional genomics studies and groundn...

The results show that genome architecture and domestication jointly shape the shrimp SV landscape; that SVs alone robustly resolve population history; and that a small set of recurrent, deletion‐bearing regulatory genes may underpin convergent improvement.

Four positively selected genes, including NADH-quinone oxidoreductase and MT-A70, harbor population-specific amino acid substitutions that may contribute to differential adaptation, potentially optimizing photosynthetic metabolism, RNA epigenetic modification, and protein homeostasis.
