The allelic composition at five glutenin loci was assessed by one-dimensional sodium dodecyl sulphate polyacrylamide gel electrophoresis (1D SDS-PAGE) on a set of 155 landraces (from 21 Mediterranean countries) and 18 representative modern varieties. Gluten strength was determined by SDS-sedimentation on samples grown under rainfed conditions during 3 years in north-eastern Spain. One hundred a...

The allelic variation at seven prolamin loci involved in quality has been studied in a set of durum wheat landraces from all the Spanish regions where this crop has been traditionally cultivated. The genetic variability was higher than that found in other germplasm collections. All the loci, except Glu-B2, displayed a genetic variability higher than 0.62, with Glu-3 the most polymorphic. In tot...

high molecular weight (hmw) glutenin sub-units and baking quality related traits were studied in 49 iranian wheat landraces. the protein content ranged from 11.2% to 13.55%, and sds sedimentation volume varied between 40 and 60 milliliters. high molecular weight glutenin electrophoresis profiles revealed that at the glu-a1 locus, the frequency of null allele was higher than sub-units 1 and 2*. ...

High molecular weight glutenin subunit composition and variation in 95 Elite-1 synthetic hexaploid (SH) wheats (Triticum turgidum/Aegilops tauschii; 2n = 6× = 42; AABBDD) were determined by sodium dodecyl sulphate polyacrylamide gel electrophoresis method (SDS-PAGE). Twenty two different alleles at Glu-1 loci in SHs were observed. Forty four different patterns of HMW-GS in synthetics were found...

The first purpose of this study was to investigate whether a GLU+FRUC beverage would result in a higher exogenous CHO oxidation rate and a higher fluid availability during exercise in the heat compared with an isoenergetic GLU beverage. A second aim of the study was to examine whether ingestion of GLU at a rate of 1.5 g/min during exercise in the heat would lead to a reduced muscle glycogen oxi...

Glutenin is a major protein fraction contributing to the functional properties of gluten and dough. The glutenin constitutes 30-40% of the protein in wheat flour and about half of that in gluten. It is essential to identify correct glutenin alleles and to improve wheat quality by selecting alleles that exert favorable effects. Moroccan wheat cultivars are unique in West Asia and North Africa re...

Gabapentin (GBP), a GABA analog that may also affect glutamate (Glu) production, can normalize GABA and Glu tone during early abstinence from alcohol, effectively treating withdrawal symptoms and facilitating recovery. Using in vivo magnetic resonance spectroscopy, we tested the degree to which daily GBP alters regional brain GABA and Glu levels in short-term abstinent alcohol-dependent individ...

Isolates of Verticillium fungicola collected in 2002 in the Veracruz State, Mexico, and previously identified as V. fungicola var. fungicola, were compared to French isolates for genetic polymorphism and diversity in some physiological traits. Results were analysed based on studies of a larger group of European V. fungicola var. fungicola. RAPD analyses showed that Mexican isolates were genetic...

The transport and metabolism of glutamine (GLN) and glutamate (GLU) during fetal development exhibit unique characteristics that clearly emphasize the importance of the interaction between the placenta and the fetal liver. GLN is delivered into the fetal circulation at a rate that is the highest of all the amino acids. In contrast, ;90% of fetal plasma GLU is extracted by the placenta. Converse...

glycine allele at codon 16 has previously been associated with the increase in asthma severity, bronchial hyperresponsiveness and also the increase in inhaled corticosteroid dependence. this study was designed to evaluate the genetic alleles in mild asthma.thirty-four patients with diagnosis of mild asthma (fev1 ≥ 80%, positive methacholine test) and body mass index (bmi ≤ 30 kg/m2) were includ...
