Genetic Linkage Map of Glu-D1 and Allelic Variation of HMW Glutenin Subunits in Some Iranian Bread Wheat genotypes
High-molecular weight (HMW (glutenin subunits are encoded by the Glu-1 loci (Glu-A1, Glu-B1 and <sp...
متن کاملAllelic variation at high-molecular weight and low-molecular weight glutenin subunit genes in Moroccan bread wheat and durum wheat cultivars
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...
متن کاملMitotic Illegitimate Recombination Is a Mechanism for Novel Changes in High-Molecular-Weight Glutenin Subunits in Wheat-Rye Hybrids
Wide hybrids can have novel traits or changed expression of a quantitative trait that their parents do not have. These phenomena have long been noticed, yet the mechanisms are poorly understood. High-molecular-weight glutenin subunits (HMW-GS) are seed storage proteins encoded by Glu-1 genes that only express in endosperm in wheat and its related species. Novel HMW-GS compositions have been obs...
متن کاملGenetic divergence for high-molecular weight glutenin subunits (HMW-GS) in indigenous landraces and commercial cultivars of bread wheat of Pakistan.
Wheat flour quality is an important consideration in the breeding and development of new cultivars. A strong association between high-molecular weight glutenin subunits (HMW-GS) and bread making quality has resulted in the widespread utilization of HMW-GS in wheat breeding. In this study, we analyzed 242 lines of wheat, including landraces from the provinces of Punjab and Baluchistan, as well a...
متن کاملCharacterization of novel LMW-GS genes at Glu-D3 locus on chromosome 1D in Aegilops tauschii.
The objectives of this study were to clarify the relationship between LMW-GS Glu-D3 gene of Ae. tauschii registered in GenBank and the six Glu-D3 genes including 12 allelic variants of common wheat characterized in our previous studies, and identify novel Glu-D3 genes and haplotypes from Ae. tauschii using gene specific PCR amplification. By searching the NCBI database, 13 LMW-GS genes/pseudoge...
