Drought stress is becoming more prevalent with global warming, and has been shown to have large effects on gluten proteins linked to wheat bread making quality. Likewise, low temperature stress can detrimentally affect proteins in wheat. This study was done to determine the differential abundance of high molecular weight (HMW) glutenin proteins in a drought and low temperature stressed high quality hard red spring wheat cultivar (PAN3478), against a control. The treatments were applied in the greenhouse at the soft dough stage. HMW glutenin proteins were extracted from the flour, and were separated by using two-dimensional gel electrophoresis. Protein spots that had p values lower than 0.05 and fold values equal to or greater than 1.2 were considered to be significantly differentially abundant. These proteins were further analyzed by using tandem mass spectrometry. There was a 1.3 to 1.8 fold change in 17 protein spots due to the cold treatment. The drought treatment caused a 1.3 to 3.8 fold change in 19 protein spots. These spots matched either HMW or low molecular weight (LMW) glutenin subunits. In the latter case, the C subunits of LMW glutenins were notably found to be up-regulated under both stress conditions. All the proteins that have been identified can directly influence dough characteristics. Data are available via ProteomeXchange with the identifier PXD017578.

Days After Anthesis

The activities of proteolytic enzymes hydrolyzing hemoglobin and azocasein were followed during the development of a hard red spring wheat cultivar. Hemoglobin and azocasein degrading activity in the outer kernel layers (pericarp, green layer and aleurone) increased until approximately 24 days after anthesis and then declined rapidly. In contrast, hemoglobin degrading activity in the endosperm increased to a maximum level at maturity. Carboxymethyl cellulose chromatography, of whole and dissected kernel extracts at various stages of development, separated the hemoglobin-degrading enzymes into two "acidic" and two "neutral" components. The acidic proteases were found mainly in the outer kernel layers, while the neutral proteases were endosperm specific. Results also indicated the presence of low and possibly high molecular weight endogenous protease inhibitors.

An apparatus and method are described for polyacrylamide gel electrophoresis of gliadins. Since the gliadin pattern (electrophoregram) is a genotypic character, electrophoresis offers a promising means for identifying wheat cultivars. Electrophoregrams are presented for a number of wheat cultivars to illustrate the results that can be obtained by the method described. A new nomenclature for gliadin bands (components) separated by this method is also presented. The nomenclature uses a major band in the electrophoregram of the Canadian hard red spring wheat cultivar Marquis as the reference. It was assigned an arbitrary mobility of 0.50; all other bands of Marquis and other cultivars are identified on the basis of electrophoretic mobility relative to 0.50 for the reference band under identical electrophoresis conditions.
