New insights into structural organization and gene duplication in a 1.75‐Mb genomic region harboring the α‐gliadin gene family in Aegilops tauschii, the source of wheat D genome

Abstract excerpt

Among the wheat prolamins important for its end-use traits, α-gliadins are the most abundant, and are also a major cause of food-related allergies and intolerances. Previous studies of various wheat species estimated that between 25 and 150 α-gliadin genes reside in the Gli-2 locus regions. To better understand the evolution of this complex gene family, the DNA sequence of a 1.75-Mb genomic region spanning the...
