| The relative percentage content of 11S and 7S and the 11S/7S value of 75 soybean landraces from Shaanxi province were investigated by Sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE) in this study.The results showed that,soybean storage protein have various subunits,in which α′,α, β,A3,Acid and Basic have a high content;Although the band type of soybean storage protein are basically the same,the content among different subunits of each landrace is significant difference.11S and 7S globulin average content were 36% and 64%,respectively,their variational range were from 28% to 48% and from 52% to 72%,respectively.11S/7S value ranged from 1.09 to 2.53,with an average of 1.78;11S/7S value was significantly different among the three cultivated regions. |
