Novel insights into the composition, variation, organization, and expression of the low-molecular-weight glutenin subunit gene family in common wheat.

ABSTRACT: 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 system and the full-length gene cloning method, a comprehensive molecular analysis of LMW-GS genes was conducted in a representative population, the micro-core collections (MCC) of Chinese wheat germplasm. Generally, >15 LMW-GS genes were identified from individual MCC accessions, of which 4-6 were located at the Glu-A3 locus, 3-5 at the Glu-B3 locus, and eight at the Glu-D3 locus. LMW-GS genes at the
