普通小麦近缘种低分子量麦谷蛋白亚基Glu-A3基因的分离和鉴定
Isolation and Characterization of LMW-GS Glu-A3 in Common Wheat Related Species
摘要
Abstract
Low-molecular-weight glutenin subunits (LMW-GS) account for about one-third of wheat seed storage proteins and have great effects on dough extensibility and food processing quality. Common wheat relative species are important genetic re-sources for wheat improvement. In this study, the specific primers of Glu-A3 genes were used to identify the allelic variations of GluA3-1, GluA-2, and GluA3-3 from nine accessions of Triticum dicoccoides, T. dicoccum, T. durum, and T. boeoricum. A total of 15 new haplotypes were identified, including five in GluA3-1, five in GluA3-2, and five in GluA3-3. Among them, two haplotypes each contained nine cysteines that might be good for improvement of wheat quality. The results about Glu-A3 genes in wheat further made clear composition of LMW-GS and provide a basis for selection of parents in wheat quality breeding.关键词
