Abstract

Background: The low molecular weight glutenin subunits (LMW-GS) of wheat have great effects on food processing quality, but the resolution of LMW-GS and the scoring of their alleles by direct analysis of proteins are difficult due to the larger number of expressed subunits and high similarity of DNA sequences. It is important to identify and classify the LMW-GS genes in order to recognize the LMW-GS alleles clearly and develop the functional markers.

Methods: The LMW-GS genes registered in GenBank were searched at NCBI, and 593 Glu-3 genes with complete coding sequences were obtained, including 146 Glu-A3, 136 Glu-B3, and 311 Glu-D3. Sequence analysis and characterization of DNA and deduced amino acids were performed using the software DNAman.

Results: The alignment and classification showed that there were at least 9 genes with 69 allelic variants at the Glu-A3 locus, 11 genes with 64 allelic variants at the Glu-B3 locus, and 10 genes with 96 variants at the Glu-D3 locus, respectively. Furthermore, the specificity of some Glu-3 genes and their variations was analyzed.

Conclusions: The results were beneficial to understanding the LMW-GS genes fully and to developing the functional markers and will provide a theoretical reference for the quality improvement of wheat variety.
