A wheat HMW glutenin subunit gene reveals a highly repeated structure.
A wheat genomic library was screened with two synthetic oligonucleotides (24 and 25 bases in length) complementary to a partial cDNA clone encoding a glutenin gene [Thompson et al. (1983) Theor. Appl. Genet. 67, 87-96]. Glutenins are large molecular weight aggregated proteins of grain endosperm, and major determinants of bread making quality of wheat. Of the two clones obtained one was fully ch...
متن کاملNucleotide sequence of a gene from chromosome 1D of wheat encoding a HMW-glutenin subunit.
A high molecular weight glutenin gene in hexaploid wheat has been isolated by cloning in bacteriophage lambda and characterized. The gene corresponds to polypeptide 12 encoded by chromosome 1D in the variety "Chinese Spring". The coding sequence predicted contains seven cysteine residues six of which flank a central repetitive region comprising more than 70% of the polypeptide. These findings a...
متن کاملMarker-Assisted Selection for Recognizing Wheat Mutant Genotypes Carrying HMW Glutenin Alleles Related to Baking Quality
Allelic diversity of HMW glutenin loci in several studies revealed that allelic combinations affect dough quality. Dx5 + Dy10 subunits are related to good baking quality and Dx2 + Dy12 are related to undesirable baking quality. One of the most regular methods to evaluate the baking quality is SDS-PAGE which is used to improve baking quality labs. Marker-assisted selection is the method which ca...
متن کاملa determination of relationship between hmw glutenin subunits and bread making quality in bread wheat
high molecular weight (hmw) subunits of wheat glutenin are generally considered as playing a key role in gluten formation and structure, as well as to be closely related to wheat quality. the endosperm storage proteins of 80 synthetic lines and wheat cultivars (triticum aestivum) were fractionated through sodium dodecyl sulfate polyacrylamide gel electrophoresis to determine their high-molecula...
متن کاملThe wheat HMW-glutenin 1Dy10 gene promoter controls endosperm expression in Brachypodium distachyon
The grass species Brachypodium distachyon has emerged as a model system for the study of gene structure and function in temperate cereals. As a first demonstration of the utility of Brachypodium to study wheat gene promoter function, we transformed it with a T-DNA that included the uidA reporter gene under control of a wheat High-Molecular-Weight Glutenin Subunit (HMW-GS) gene promoter and tran...
