Quantitative trait loci of stripe rust resistance in wheat
Key message: Over 140 QTLs for resistance to stripe rust in wheat have been published and through mapping flanking markers on consensus maps, 49 chromosomal regions are identified. Abstract: Over thirty publications during ...
Molecular mapping of leaf rust resistance gene LrNJ97 in Chinese wheat line Neijiang 977671
Neijiang 977671 and 19 near-isogenic lines with known leaf rust resistance genes were inoculated with 12 pathotypes of Puccinia triticina for postulation of leaf rust resistance genes effective at the seedling stage. The ...
Aegilops tauschii draft genome sequence reveals a gene repertoire for wheat adaptation
About 8,000 years ago in the Fertile Crescent, a spontaneous hybridization of the wild diploid grass Aegilops tauschii (2n = 14; DD) with the cultivated tetraploid wheat Triticum turgidum (2n = 4x = 28; AABB) resulted in ...
Effects of high molecular weight glutenin subunits on wheat quality by Aroona and its near-isogenic lines
Objective: The effects of high molecular weight glutenin subunits (HMW-GS) on dough properties, quantity of gluten protein fractions, and bread-making quality were determined under the same genetic background of low molecular ...
QTL mapping of adult-plant resistances to stripe rust and leaf rust in Chinese wheat cultivar Bainong 64
Stripe rust and leaf rust, caused by Puccinia striiformis Westend. f. sp. tritici Erikss. and P. triticina, respectively, are devastating fungal diseases of common wheat (Triticum aestivum L.). Chinese wheat cultivar Bainong ...
Allelic variation at the TaZds-A1 locus on wheat chromosome 2A and development of a functional marker in common wheat
zeta)-carotene desaturase (ZDS) is a key enzyme for carotenoid biosynthesis, demonstrating high association with the yellow pigment (YP) content in wheat grain. Cloning ZDS gene and developing functional markers are important ...
Physical mapping of Puroindoline b-2 genes in wheat using 'Chinese spring' chromosome group 7 deletion lines
The puroindoline genes (Puroindoline a-D1 and Puroindoline b-D1), located very near to the distal end of the short arm of chromosome 5D (distal to fraction arm length of 0.78) have a significant effect on grain hardness. ...

Comparison of low molecular weight glutenin subunits identified by SDS-PAGE, 2-DE, MALDI-TOF-MS and PCR in common wheat
Background: Low-molecular-weight glutenin subunits (LMW-GS) play a crucial role in determining end-use quality of common wheat by influencing the viscoelastic properties of dough. Four different methods - sodium dodecyl ...
Functional markers in wheat: current status and future prospects
Functional markers (FM) are developed from sequence polymorphisms present in allelic variants of a functional gene at a locus. FMs accurately discriminate alleles of a targeted gene, and are ideal molecular markers for ...
