Figure 1.

Alpha‐gliadin peptide variant expression profiles in grains of Aegilops tauschii (Ent lines) and Triticum aestivum accessions.

The peptide variants were differentially abundant in the accessions. The accessions were clustered based on their peptide variant expression profile using hierarchical clustering with Spearman rank correlation with average linking. Purple triangles highlight the main clusters. Ent lines marked with * and ** contain peptide variants with the 33‐mer. *Variant J234. **Variant J2 and J29. Variant J2 was also found in all of the nine bread wheat accessions.
