The fractionation and characterization of cereal proteins may be among the most difficult problems in biochemistry: these proteins are heterogeneous. have unusual solubility characteristics. and have marked tendencies to aggregate. both covalently and noncovalently. Recent reviews (Bietz and Huebner 1980. Kasarda et a11976. Khan and Bushuk 1979. Miflin and Shewry 1979. Wall 1979) demonstrate th...

Bread is one of the most important processed foods wheat flour worldwide. Breadmaking quality determined by grain protein content and its composition highly influenced fertilization management. This study investigated effects spraying different combinations exogenous regulators on breadmaking flour. Three schemes including Potassium glutamate+Zinc+Urea (G), Methionine+ Zinc+Urea (M), Cysteine+ ...

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 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...
