【摘要】 利用十二烷基硫酸钠-聚丙烯酰胺凝胶电泳(SDS-PAGE)方法对国外31份优质小麦的高分子量麦谷蛋白亚基(HMW-GS)进行了分析,结果表明,GI U-A1位点上有3种类型:N、1、2*;GI U-B1位点上有6种类型:7、6+8、7+8、7+9、13+16、17+18;GI U-D1位点上有2种类型:5+10、2+12。也出现了一些稀有亚基,在GI U-A1位点上以1为主。更多还原

【Abstract】 The sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE) was used to analyze the HMW-GS composition of 31 foreign wheat genotpes with good-quality.The result showed that there were 3 types of HMW-GS(N,1,2*) at Glu-A1 locus,6 types 7,6+8,7+8,7+9,13+16,17+18 at Glu-B1,and two types 5+10,2+12 at Glu-D1.Some rare subunits were also detected in the study.The main HMW-GS at Glu-A1 was 1.It is necessary to introduce some good-quality varieties as parents in wheat quality improvement.更多还原
