Allelic analysis of low molecular weight glutenin subunits using 2-DGE in Korean wheat cultivars.

ABSTRACT: Two-dimensional gel electrophoresis (2-DGE) was used as a complement to SDS-PAGE to determine the allelic compositions of LMW-GS in 32 Korean wheat cultivars. Protein patterns generated by 2-DGE from each cultivar were compared to patterns from standard wheat cultivars for each allele. At the Glu-A3 locus, thirteen c, twelve d, three e (null), two g and two new alleles were identified. At the Glu-B3 locus, one b, nineteen d, four h, one i and five ad alleles were identified. At the Glu-D3 locus, twenty-three a, four b, four c and one l alleles were identified. When compared to results obtained previously using SDS-PAGE, there were discrepancies in the allelic designations of 10 of 32 cultivars (31%). While SDS-PAGE is a rapid and relatively simple method for assessing LMW-GS composition, t
