Identification and Characterization of High-Molecular-Weight Glutenin Subunits from Agropyron intermedium

High-molecular-weight glutenin subunit (HMW-GS) is a primary determinant of processing quality of wheat. Considerable progress has been made in understanding the structure, function and genetic regulation of HMW-GS in wheat and some of its related species, but less is known about their orthologs in Agropyron intermedium, a useful related species for wheat improvement. Here seven HMW-GSs in Ag. ...

Evaluation and characterization of high-molecular weight 1D glutenin subunits from Aegilops tauschii in synthetic hexaploid wheats

The high-molecular weight (HMW) glutenin subunits of bread wheat are major determinants of end-use quality. The objective of this study was to determine the 1Dx and 1Dy subunits present in 43 synthetic hexaploid wheat (SHW) lines derived by crossing durum ‘Langdon’ to 43 Aegilops tauschii accessions. Protein samples were initially electrophoresed multiple times on SDS-PAGE gels to arrange subun...

Variant high-molecular-weight glutenin subunits arising from biolistic transformation of wheat

Genetic transformation via the biolistic method has been used to introduce genes encoding natural and novel high-molecular-weight glutenin subunits (HMW-GS) into wheat. The appearance of new seed proteins of sizes not predicted by the transgene coding sequences was noted in some experiments. In this report, the identities of thirteen of these novel proteins were determined by tandem mass spectr...

Identification of Intact High Molecular Weight Glutenin Subunits from the Wheat Proteome Using Combined Liquid Chromatography-Electrospray Ionization Mass Spectrometry

The present paper describes a method for the identification of intact high molecular weight glutenin subunits (HMW-GS), the quality determining proteins from the wheat storage proteome. The method includes isolation of HMW-GS from wheat flour, further separation of HMW-GS by reversed-phase high-performance liquid chromatography (RP-HPLC), and their subsequent molecular identification with elect...

identification of low molecular weight glutenin subunits in triticum aestivum and the d genome of wild related wheat

in this study, 110 samples of bread wheat, aegilops crassa, ae. cylindrica and ae. tauschii were investigated to identify low-molecular-weight glutenin subunits. overall, the four alleles in term of the analysis of sds-page gels were detected. the ʻaʼ allele with 45% has the greatest frequency, and after that, ʻbʼ, ʻcʼ and ʻdʼ alleles were with 38.1%, 11.8% and 9.1% frequencies, respectively; h...
