二倍体长穗偃麦草(Thinopyrumelongatum)E组染色体携带有对小麦遗传育种有益的基因。通过SDS-PAGE,分析了9份二倍体长穗偃麦草的高分子量谷蛋白亚基类型,初步发现有6种等位变异类型,显示了二倍体长穗偃麦草E组染色体携带有丰富的高分子量谷蛋白亚基(HMW-GS)等位基因类型,是普通小麦进行品质改良的重要基因资源。
The chromosome group E of the diploid Thinopyrumelongatum carries genes useful for wheat genetic breeding. By SDS-PAGE, we analyzed the HMW glutenin subunit types in nine diploid long-tailed Agrocybe aegerus. Six allelic variants were found, indicating that the chromosomes of E HMW-GS allele is the important gene resource for wheat quality improvement.
