Based on the electrophoretic spectrum, analysis, 216 genotypes of spring wheat were identified as belonging to 25 types including 18 types of HMW-glutenin for 188 homogeneous cultivars. Most of the spring wheat KASIB could be characterized by the subunits 2 * 7+9 5+10 (40% genotypes), and subunits 2* 7+9 2+12– (30%) and subunits 1*7+9 5+10– (8%). The diversity appears to be determined by varyin...

bread-making quality in hexaploeid wheat is a complex trait for breeding programs. high molecular weight glutenin subunits (hmw-gs) have an important effect on dough stability and elasticity. the glu-1 loci that are encoded these subunits are located on the long arms of group-1 homologues chromosomes of the a, b and d genomes. in this work we used pcr-based dna markers to distinguish wheat brea...

Certain cereals like wheat, rye or barley contain gluten, a protein mixture that can trigger celiac disease (CD). To make gluten-free diets available for affected individuals the gluten content of foodstuff must be monitored. For this purpose, antibody-based assays exist which rely on the recognition of certain linear gluten sequence motifs. Yet, not all CD-active gluten constituents and fragme...

The wheat gluten proteins correspond to the major storage proteins that are deposited in the starchy endosperm cells of the developing grain. These form a continuous proteinaceous matrix in the cells of the mature dry grain and are brought together to form a continuous viscoelastic network when flour is mixed with water to form dough. These viscoelastic properties underpin the utilization of wh...

Wheat gluten proteins, gliadins and glutenins, are of great importance in determining the unique biomechanical properties of wheat. Studies have therefore been carried out to determine their pathways and mechanisms of synthesis, folding, and deposition in protein bodies. In the present work, a set of transgenic wheat lines has been studied with strongly suppressed levels of γ-gliadins and/or al...

Hydrolysis and depolymerization of gluten proteins during sourdough fermentation were determined. Neutral and acidified doughs in which microbial growth and metabolism were inhibited were used as controls to take into account the proteolytic activity of cereal enzymes. Doughs were characterized with respect to cell counts, pH, and amino nitrogen concentrations as well as the quantity and size d...

BACKGROUND AND AIMS Gluten proteins are the major storage protein fraction in the mature wheat grain. They are restricted to the starchy endosperm, which forms white flour on milling, and interact during grain development to form large polymers which form a continuous proteinaceous network when flour is mixed with water to give dough. This network confers viscosity and elasticity to the dough, ...

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...
