Abstract excerpt
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...
