The goat grass genome’s role in wheat improvement

The recently published reference genome of Aegilops tauschii provides new insights into the originator of the D genome donor of hexaploid wheat. This will be a foundation for exploring the genomic diversity underpinning adaptive traits in wheat, and ultimately advance wheat improvement efforts.
