Abstract
The quality of wheat primarily depends on its storage protein quality, especially in regards to gluten content and high-molecular-weight glutenin subunits (HMW-GS). The number of HMW-GS alleles is limited in bread wheat (Triticum aestivum L.), whereas it is abundant in wheat relatives. Therefore, HMW-GS alleles from wheat relatives could provide a potential for improving quality in wheat breeding. Thinopyrum elongatum (EE) is one of the relatives of wheat. The E genome is closely related to the ABD genome in wheat; therefore, Th. elongatum is often used as an excellent exogenous gene donor for wheat genetic improvement. In this study, the high-molecular glutenin subunit gene was cloned and sequenced from Th. elongatum. A specific molecular marker for identifying the Glu-1Ey subunit gene was developed and applied to detected wheat-Th. elongatum alien introgression lines. Quality analysis indicated that the substitution and addition lines containing Th. elongatum alleles significantly (p < 0.05) increased grain protein content by 3.76% to 5.11%, wet-gluten content by 6.55% to 8.73%, flour 8-MW by 0.25% to 6.35%, and bread volume value by 33.77 mL to 246.50 mL, in comparing it with Chinese Spring. The GMP content and lactic acid SRC showed significant positive correlations with flour processing quality and might be used as indicators for wheat quality. The results were expected to provide a novel route for improving processing quality in wheat quality breeding.

Abstract
As an important relative of wheat (Triticum aestivum L), Dasypyrum breviaristatum contains novel high molecular weight glutenin subunits (HMW-GSs) encoded by Glu-1Vb genes. We identified new wheat-D. breviaristatum chromosome introgression lines including chromosomes 1Vb and 1VbL.5VbL by fluorescence in situ hybridization (FISH) combined with molecular markers. We found that chromosome changes occurred in the wheat-D. breviaristatum introgression lines and particularly induced the deletion of 5BS terminal repeats and formation of a new type of 5B-7B reciprocal translocation. The results imply that the D. breviaristatum chromosome 1Vb may contain genes which induce chromosomal recombination in wheat background. Ten putative high molecular weight glutenin subunit (HMW-GS) genes from D. breviaristatum and wheat-D. breviaristatum introgression lines were isolated. The lengths of the HMW-GS genes in Dasypyrum were significantly shorter than typical HMW-GS of common wheat. A new y-type HMW-GS gene, named Glu-Vb1y, was characterized in wheat-D. breviaristatum 1Vb introgression lines. The new wheat-D. breviaristatum germplasm displayed reduced plant height, increased tillers and superior grain protein and gluten contents, improved gluten performance index. The results showed considerable potential for utilization of D. breviaristatum chromosome 1Vb segments in future wheat improvement.

Abstract
The Roegneria of Triticeae is a large genus including about 130 allopolyploid species. Little is known about its high-molecular-weight glutenin subunits (HMW-GSs). Here, we reported six novel HMW-GS genes from R. nakaii and R. alashanica. Sequencing indicated that Rny1, Rny3, and Ray1 possessed intact open reading frames (ORFs), whereas Rny2, Rny4, and Ray2 harbored in-frame stop codons. All of the six genes possessed a similar primary structure to known HMW-GS, while showing some unique characteristics. Their coding regions were significantly shorter than Glu-1 genes in wheat. The amino acid sequences revealed that all of the six genes were intermediate towards the y-type. The phylogenetic analysis showed that the HMW-GSs from species with St, StY, or StH genome(s) clustered in an independent clade, varying from the typical x- and y-type clusters. Thus, the Glu-1 locus in R. nakaii and R. alashanica is a very primitive glutenin locus across evolution. The six genes were phylogenetically split into two groups clustered to different clades, respectively, each of the two clades included the HMW-GSs from species with St (diploid and tetraploid species), StY, and StH genomes. Hence, it is concluded that the six Roegneria HMW-GS genes are from two St genomes undergoing slight differentiation.

Abstract
Pseudoroegneria is a small genus of the Triticeae tribe; its St genome is present in over half of allopolyploid Triticeae species. The high molecular weight (HMW) subunits of glutenin (GS) encoded by the St genome are not well described. In this paper, we report the characterization of fourteen alleles of HMW-GS genes from the two species Pd. spicata and Pd. strigosa. Analysis shows that all fourteen sequences possess a typical primary structure shared by other known HMW-GS, but with some unique modifications. All fourteen Glu-St1 alleles are significantly smaller than normal Glu-1 genes due to fewer repeat motifs in a repetitive region with no indication of large deletion in other conserved regions. Thus, the small size is a common feature of HMW-GS encoded by Glu-St1 loci of Pseudoroegneria species. Sequence analysis indicated that all fourteen Glu-St1 alleles were intermediate type between x- and y-type, which represent an intermediate stage in the evolutionary divergence of x- and y-type subunits.

Abstract
BACKGROUND High molecular weight glutenin subunits (HMW-GSs), encoded by the genes at Glu-1 loci in wheat and its related species, are significant in the determination of grain processing quality. However, the diversity and variations of HMW-GSs are relatively low in bread wheat. More interests are now focused on wheat wild relatives in Triticeae. The genus Aegilops represents an important germplasm for novel HWM-GSs and other useful genes for wheat genetic improvement. RESULTS Six novel Glu-1 alleles and HMW-GSs were identified and characterized from three species of Aegilops section Sitopsis (S genome). Both open reading frames (ORFs) and promoter regions of these Glu-1 alleles were sequenced and characterized. The ORFs of Sitopsis Glu-1 genes are approximately 2.9 kb and 2.3 kb for x-type and y-type subunits, respectively. Although the primary structures of Sitopsis HMW-GSs are similar to those of previously reported ones, all six x-type or y-type subunits have the large fragment insertions. Our comparative analyses of the deduced amino acid sequences verified that Aegilops section Sitopsis species encode novel HMW-GSs with their molecular weights larger than almost all other known HMW-GSs. The Glu-1 promoter sequences share the high homology among S genome. Our phylogenetic analyses by both network and NJ tree indicated that there is a close phylogenetic evolutionary relationship of x-type and y-type subunit between S and D genome. CONCLUSIONS The large molecular weight of HMW-GSs from S genome is a unique feature identified in this study. Such large subunits are resulted from the duplications of repetitive domains in Sitopsis HMW-GSs. The unequal crossover events are the most likely mechanism of variations in glutenin subunits. The S genome-encoded subunits, 1Dx2.2 and 1Dx2.2* have independent origins, although they share similar evolutionary mechanism. As HMW-GSs play a key role in wheat baking quality, these large Sitopsis glutenin subunits can be used as special genetic resources for wheat quality improvement.

Abstract
The St genome, which is present in nearly half of all Triticeae species, originates from the genus Pseudoroegneria. However, very little is known about the high molecular weight (HMW) subunits of glutenin which are encoded by the St genome. In this paper, we report the isolation from Pd. libanotica of four sequences encoding HMW subunits of glutenin. The four genes were all small compared to standard glutenin genes. All four sequences resemble y-type glutenins rather than x-types. However, their N-terminal domains contain a glutamine residue which is present in all x-type, but very few y-type subunits, and their central repetitive domains included some irregular motifs. The indication is therefore that the Glu-1St genes evolved earlier than other modern day homoeologues, so that they represent an intermediate state in the divergence between x- and y-type subunits. No x-type Glu-1St subunit genes were identified.

Abstract
The Triticeae species Australopyrum retrofractum (genome WW) produces a single high molecular weight glutenin subunit (HMW-GS) in its endosperm. However, degenerate PCR amplification of its genome DNA revealed the presence of two related HMW-GS sequences, each consisting of an open reading frame. One of these (Glu-W1-2) has not previously been reported. Here, we sequenced Glu-W1-2 and showed that it encodes the same type of HMW-GS as Glu-W1-1, although its overall product length was much shorter, because the number of certain repetitive motifs was lower in its central region. Both A. retrofractum HMW-GSs have a unique repetitive motif, which differentiates them from other known x- and y-type subunits present in Triticeae species. We suggest that A. retrofractum must have diverged from the main Triticeae lineage prior to the Glu-1 duplication event which led to the evolution of the x- and y-type genes.

Abstract
A genomic polymerase chain reaction (PCR) cloning strategy was applied to isolate ω-gliadin sequences from three A-genome diploid wheats (Triticum monococcum, T. boeoticum and T. urartu). Amplicon lengths varied from 744 and 1,044 bp, and those of the corresponding deduced mature proteins from 248 to 348 residues. The primary structure of the deduced polypeptides comprised a short N- and C-terminal conserved domain, and a long, variable repetitive domain. A phylogenetic analysis recognised several clades: the first consisted of three T. aestivum sequences; the second and the third two T. boeoticum and six T. monococcum sequences; and the rest four T. urartu and three T. aestivum sequences. Among the functional (non-pseudogene) ARQ/E-type ω-gliadin sequences, two were derived from T. boeoticum and three from T. monococcum; one of the latter sequences appeared to be a chimera originating via illegitimate recombination between the other two T. monococcum sequences. None of the 12 intact ω-gliadin sequences contained any cysteine or methionine residues. We discussed the variation and evolution of A-genome ω-gliadin genes.
