Low-molecular-weight glutenin subunits (LMW-GS) are of great importance in processing quality and participate in the formation of polymers in wheat. In this study, eight new LMW-GS alleles were isolated from Chinese wheat landraces (Triticum aestivum L.) and designated as Glu-A3-1a, Glu-A3-1b, Glu-B3-1a, Glu-B3-1b, Glu-B3-1c, Glu-D3-1a, Glu-D3-1b, and Glu-D3-1c, which were located at the Glu-A3...
The B low Mr subunits of glutenin of the F2 generation from three durum wheat crosses were analysed. Three new alleles were found at three different loci: Glu-A3i coding for 5C20 subunits, Glu-B2c coding for subunit 12* and Glu-B3l coding for 1C3C13*C16 subunits. The genetic distances between Glu-A3-Gli-A1, Glu-B2-Gli-B1, Glu-B3-Glu-B2 and Glu-B3-Gli-B1 were calculated. The effects of the allel...
to evaluate allelic diversity at loci encoding low molecular weight glutenin subunits (lmw-gs) among 62 genotypes of bread wheat, nine specific primer pairs for glu-a3, glu-b3, glu-d3 loci were employed. pcr products were separated on 2% agarose gels. two pairs of specific primers, at amplified glu-a3 locus, 8 alleles were detected the c allele of which was the most abundant with a frequency of...
Low molecular weight glutenin subunits are important components of wheat storage proteins, which play an important role in determining end-use quality of common wheat. A newly established matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) procedure was used to analyze 478 landraces of bread wheat collected from the Yangtze-River region in China. Results ...
Marker assisted selection (MAS) is a tool for breeding, screening, and genetic characterization of germplasm. Allelic variation of both high and low molecular weight glutenin subunits (HMW/LMW-GS) is associated with the rheological properties of wheat flour. In this study, we investigated glutenin pattern using SDS-PAGE and their PCR based on DNA markers in 60 advanced wheat lines and cultivars...
جهت بررسی تنوع آللی در بلوکهای ژنی کدکننده پروتئینهای ذخیرهای گندم زیر واحدهای گلوتنین با وزن مولکولی پایین (LMW-GS) بین 62 ژنوتیپ از گندمهای نان، نه جفت آغازگر اختصاصی برای مکانهای ژنی (Glu-A3, Glu-B3, Glu-D3) بکار گرفته شد. برای تفکیک محصولات واکنش PCR از ژل آگاروز 2 درصد استفاده شد. نتایج نشان داد که تنوع قابل ملاحظهایی بین ژنوتیپهای گندم نان ایران وجود دارد. بطوری که برای بلوک ژنی G...

We investigated the relationships of three allelic variations in Glu-B3 (ab, g, and h) with dough properties and bread-making quality-related characteristics using near-isogenic lines (NILs) of 'Yumechikara' that commonly carry Glu-A1a, Glu-B1b, Glu-D1d, Glu-A3f, Glu-B3ab and Glu-D3a. Measurement of peak time (PT) in a 2-g mixograph indicated that Glu-B3g was the most effective for a strong dou...
Sodium dodecyl sulfate (SDS) sedimentation volume has long been used to characterize wheat flours and meals with the aim of predicting processing and end-product qualities. In order to survey the influence of low-molecular-weight glutenin subunits (LMW-GSs) at Glu-B3 locus on wheat SDS sedimentation volume, a total of 283 wheat (Triticum aestivum L.) varieties including landraces and improved a...
Low-molecular-weight glutenin subunits (LMW-GS), encoded by a complex multigene family, play an important role in the processing quality of wheat flour. Although members of this gene family have been identified in several wheat varieties, the allelic variation and composition of LMW-GS genes in common wheat are not well understood. In the present study, using the LMW-GS gene molecular marker sy...
