title: [Genetic analysis of contribution of low-molecular-weight glutenin subunits to dough strength in common wheat].
abstract: Locus-specific primers of low-molecular-weight glutenin subunit (LMW-GS) genes and gliadin bands tightly linked to LMW-GS genes were analyzed to evaluate the effect of LMW-GS genes on dough strength in common wheat (Triticum aestivum L.). Analysis of the F9 progeny from two crosses '99G45/Jing771' and 'Pm97034/J771' showed that the LMW-GS genes located at the Glu-B3 locus from the three parents had six Cysteine, but 'PB' (define) had a seven amino-acid deletion in the repetitive to 'GB' and 'JB' (define these abbreviations) and amino-acid substitution, two of which would be expected to cause changes in hydrophilicity.
