【摘要】 通过十二硫酸酯钠—聚丙烯酰胺凝胶电泳技术(SDS-PAGE),对108个小麦品种(系)的高分子量谷蛋白亚基分析。结果表明,材料中亚基组成丰富,检测到15种亚基和26种亚基组成。其中,在Glu-A1位点上,1亚基出现的频率最高,为59.3%;在Glu-B1位点上,7+8亚基类型出现的频率最高,为27.8%;在Glu-D位点上,2+12亚基出现频率最高,达68.5%,5+10亚基出现频率为17.6%。在所分析的材料中,还出现了少见的特殊亚基6*+8*。更多还原

【Abstract】 The compositions of high molecular weight glutenin subunit of 108 wheat materials were studied with the method of SDS-PAGE.The results showed that the HMW-GS compositions of 108 wheat materials were extremely(abundant.) 15 subunit patterns and 26 subunit combinations were detected.At the Glu-A1 loci,frequency of subunit 1 was the highest(59.3%),at the Glu-B1 loci,frequency of subunit(7+8) was the highest(27.8%),at the Glu-D1 loci,frequency of subunit(2+12) was the highest(68.5%),frequency of subunit(5+10) was 17.6%.In analysis of wheat lines the special subunit(6~*+8~*) was also observed.更多还原
