应用蛋白质双向电泳技术分析了普通野生稻、粳稻以及籼稻种子的贮藏蛋白组分。结果表明,各品种在电泳图的第Ⅲ,Ⅳ和Ⅴ区有相同的蛋白质组分;而在第Ⅰ区和第Ⅱ区,三者间有特征性的差异。经鉴定,第Ⅰ区及第Ⅱ区的蛋白质主要是谷蛋白,因此谷蛋白的变异情况决定着野生稻进化成粳稻还是籼稻。 The protein components of common wild rice, japonica rice and indica rice were analyzed by two-dimensional electrophoresis. The results showed that each species had the same protein components in the Ⅲ, Ⅳ and Ⅴ regions of the electrophoresis pattern; while in the Ⅰ region and Ⅱ region, there was a characteristic difference among the three. It has been identified that the proteins in Zone I and Zone II are mainly gluten. Therefore, the variation of gluten determines the evolution of wild rice into japonica or indica.
