2. Effect of glutenin subunits on the baking quality of Brazilian wheat genotypes
ABSTRACT This study aimed to evaluate the effect of the high and low molecular weight glutenin subunits on the grain traits of sixteen Brazilian wheat genotypes. Grain hardness index, milling traits, physicochemical and rheological properties of the flour, and specific volume and firmness of the bread were evaluated. Physicochemical properties of the flour w

3. Effects of genotype and environment on grain yield and quality traits in bread wheat (T. aestivum L.)
Genotype (G), environment (E) and their interaction (GEI) play an important role in the final expression of grain yield and quality attributes. A multi-environment trial in wheat was conducted to evaluate the magnitude of G, E and GEI effects on grain yield and quality of wheat genotypes under the three rainfed locations (hereafter environment) of Central An

4. Proteínas del gluten y reología de trigos harineros mexicanos influeciados por factores ambientales y genotípicos
The objective of this study was to determine the effect of environmental and genotypic factors on industrial quality and on the monomeric and polymeric protein contents and ratio of 24 rainfed bread wheat recombinant lines. The cultivation was done in five environmental conditions generated by agronomic management in the autumn-winter 2006/2007 cycle, at Roq

5. Perfil protéico e qualidade de panificação em linhagens de trigo desenvolvidas para a região do cerrado brasileiro / Profile protein and quality of bakery in strains of wheat developed for the region of the Brazilian Cerrado
The region of Cerrado constitutes important alternative in the expansion of Brazilian wheat area, considering the need of wheat supply for milling industries of the country and the expenses with this cereal import. Besides, there is the difficulty of alternatives of winter crops. Nonetheless, wheat cultivation in Cerrado and Minas Gerais State demands the de

6. Tissue-specific expression of a wheat high molecular weight glutenin gene in transgenic tobacco.
The expression of a wheat genomic clone containing the entire coding sequence of the high molecular weight glutenin subunit 12 gene flanked by 2.6 kilobases of 5' and 1.5 kilobases of 3' sequences has been studied after introduction into tobacco. Seeds of different tobacco plants containing the full-length wheat genomic clone accumulated different amounts of

7. Identification of an enhancer element for the endosperm-specific expression of high molecular weight glutenin.
Genes encoding high molecular weight (HMW) glutenin, a wheat seed storage protein, are expressed only in the developing endosperm. It was previously demonstrated that sequences essential for endosperm-specific transcription reside within 436 base pairs upstream of the initiation codon for HMW glutenin translation. We have further analyzed this region by test

8. Heterologous expression of a wheat high molecular weight glutenin gene in Escherichia coli.
An engineered DNA fragment containing a DNA sequence encoding a wheat high molecular weight glutenin subunit was cloned into a bacterial expression vector that is based on bacteriophage T7 RNA polymerase. The resulting plasmid directed the synthesis of large amounts of the mature form of the wheat high molecular weight glutenin subunit in Escherichia coli. T

9. Characterization of a Low-Molecular-Weight Glutenin Subunit Gene from Bread Wheat and the Corresponding Protein That Represents a Major Subunit of the Glutenin Polymer1
Both high- and low-molecular-weight glutenin subunits (LMW-GS) play the major role in determining the viscoelastic properties of wheat (Triticum aestivum L.) flour. To date there has been no clear correspondence between the amino acid sequences of LMW-GS derived from DNA sequencing and those of actual LMW-GS present in the endosperm. We have characteriz

10. 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

11. Localization of sequences in wheat endosperm protein genes which confer tissue-specific expression in tobacco
The developing cereal grain accumulates large quantities of proteins which are unique to the endosperm tissue. The DNA sequences which determine their endosperm-specific expression have not yet been identified. In the absence of a suitable transformation-regeneration system for cereals, we have investigated whether chimaeric genes consisting of low mol. wt (

12. Nucleotide 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%
