将野生大豆高蛋白等优良性状转移到栽培大豆上去,在遗传操作和育种实践中已引起广泛的重视。为此,了解从野生到栽培的演变过程中,贮存蛋白发生了什么样的变化是十分重要的。贮存蛋白绝大部分是球蛋白。本工作将野生大豆(G. soja)、半野生大豆(G.gracilis)和栽培大豆(G.max)的球蛋白组分进行了比较研究。现简报如下。按Appu Rao和Narasinga Rao的方法,以Mg~(++)和不同饱和度(NH_4)_2SO_4。使各种球蛋白分离。通过沉降系数的测定和凝胶电泳的分析对11S、7S和2S三种球蛋白加以鉴定。对属于野生大豆、半 The high-protein wild soybean and other fine traits transferred to the cultivation of soybeans, genetic manipulation and breeding practice has attracted widespread attention. For this reason, it is important to understand what happens to stored protein during the evolution from wild to cultivated. The vast majority of stored protein is globulin. In this work, the globulin components of G. soja, G. gracilis and G. max were compared. Now briefing as follows. According to Appu Rao and Narasinga Rao method, with Mg ~ (++) and different saturation (NH_4) _2SO_4. So that a variety of globulin separation. The 11S, 7S and 2S three globulin were identified by sedimentation coefficient and gel electrophoresis analysis. For wild soybeans, half
