The new branched spike forms of wheat were synthesized from the crosses between a complex wheat line 171ACS {Aegilotriticale [(T. durum Desf. × Ae. tauschii Coss.) × Secale cereale L. ssp. segetale Zhuk.] × T. aestivum L. ‘Chinese Spring’} (2n = 6x = 42, AABBDD) and durum wheat variety T. durum Desf. ‘Bereketli-95’ (2n = 4x = 28, AABB) and also between a dwarf line 237KACS (Aegilotriticale × T....
Mechanisms leading to the assembly of wheat storage proteins into proteins bodies within the endoplasmic reticulum (ER) of endosperm cells are unresolved today. In this work, physical chemistry parameters which could be involved in these processes were explored. To model the confined environment of proteins within the ER, the dynamic behavior of gamma-gliadins inserted inside lyotropic lamellar...
BACKGROUND AND AIMS The ω-gliadin storage proteins of wheat are of interest in relation to their impact on grain processing properties and their role in food allergy, particularly the ω-5 sub-group and wheat-dependent exercise-induced anaphylaxis. The ω-gliadins are also known to be responsive to nitrogen application. This study therefore compares the effects of cultivar and nitrogen availabili...
Field trials were conducted to evaluate the effect of nitrogen level on wheat protein content and composition in 16 cultivars over two years at three locations. The treatment comprised levels, 0 kg ha?1 as low 100 high nitrogen, applied top dressings 50 per ha tillering stem extension growth stages. Increased generally enhanced grain by 11.3% (11.5% vs. 12.8%). Considering determined reversed p...
the aim of the present study was to characterize allergen-specific immunoglobulin e (ige) among children in fez region. eighty one children were recruited from the hospital university center of fez. all of them had completed a questionnaire before taking sera. the sera were used to measure total ige and specific data to proteins of egg's white (ewp), peanuts (pp) and gliadins (g). in last part,...
Celiac disease is caused by an uncontrolled immune response to gluten, a heterogeneous mixture of wheat storage proteins, including the α-gliadins. It has been shown that α-gliadins harbor several major epitopes involved in the disease pathogenesis. A major step towards elimination of gluten toxicity for celiac disease patients would thus be the elimination of such epitopes from α-gliadins. We ...
There is a growing interest in plant protein based nanoparticles (NPs) such as wheat gliadin NPs (GNPs) for stabilizing foams food systems. To increase the range of their applications, it necessary to understand role different types and tailor behavior at air-water (A-W) interfaces. The latter here done by modifying GNPs with microbial transglutaminase (TG). most pronounced solubility loss ?-gl...
Polypeptide chain weights of a-, 8and y-gliadin fractions have been estimated by polyacrylamide gel electrophoresis in the presence of mercaptoethanol and sodium dodecyl sulphate. Values lie in the range 32 000 to 44 OOO. When available data on the amino acid analyses were adjusted and compared, significant similarities emerged. It is suggested that these gliadins contain a minimum of 4 cystine...
1. Highly purified ω-gliadins from wheat were used to challenge gluten-sensitized individuals. Characteristic responses by mucosal CD3+ and γδ+ lymphocytes were demonstrated. Each lymphocyte subset showed an increase within 8–12 h post-challenge, indicating a specific response by the rectal mucosa to this gliadin species. 2. Available sequence data for the ω-gliadins and homologous proteins fro...
BACKGROUND Peptides from alpha-gliadins have been used to characterise the immunodominant coeliac toxic epitope. A peptide corresponding to amino acid residues 57-73 of A-gliadin causes peripheral blood mononuclear cells from coeliac patients to secrete interferon gamma (IFN-gamma); gluten specific small intestinal T cell clones proliferate in response to peptides corresponding to residues 57-6...
