Molecular characterization of novel high-molecular-weight glutenin subunit genes from <i>Aegilops tauschii</i>.

ABSTRACT: The Glu-D1 locus is known to contribute the most to gluten quality in common wheat. Aegilops tauschii, as a donor species of the common wheat D genome, is of great significance for improving wheat flour processing quality by exploring and utilizing its excellent quality-related genes. In this study, high-molecular-weight glutenin subunit (HMW-GS) compositions of 173 Aegilops tauschii accessions from the Middle East, Central Asia, and Xinjiang were analyzed using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) technology. A total of 13 subunit types were detected at the Glu-D1 ^t locus, including the unique subunit types absent in common wheat. Unexpectedly, all these Ae. tauschii accessions lacked the extra cysteine residue
