The paper shows that chromosomal rearrangements and sequence similarity drive preferential introgression of genes from a wild wheat relative into wheat via ph1b-mediated recombination.

The paper identifies and analyzes Rec8-like homoeologous genes in wheat, revealing structural differences and differential expression patterns that suggest unique evolutionary dynamics of the B subgenome.

The paper identifies homology between wheat chromosome 1B and Ae. speltoides chromosome 1S, suggesting Ae. speltoides contributed to the wheat B genome's origin but is not its exclusive ancestor.
