大豆种子蛋白亚基及11S/7S随种子发育的变化规律
Changes of Soybean Seed Protein Subunits and 11S/7S with Seed Development
摘要
Abstract
In order to promote the improvement of soybean protein quality,understand the dynamic changes of subunits of 11S and 7S components during the development of soybean seeds.in this study,SDS-PAGE was used to study the changes of protein subunits in four different soybean varieties during seed development.During seed development,it was found that the accumulation of β subunits in the variety Zhongji 601(44.82％)with high protein content in the S4 stage was significantly higher than that of other varieties with low protein content.The accumulation of subunits in the 11S component of different soybean varieties was significantly different at different stages.Among the two varieties with low 11S/7S ratios,Zhongji 601(1.059)and Jilin xiaolidou had a lower content of Basic subunits in the 11S component during the S3-S9 period compared to other subunits,while the two varieties with high 11S/7S ratios,Heihe 23(1.324)and Suinong 28(1.401),had a higher content of Basic and Acid subunits in the 11S component during the S3-S9 period compared to other subunits,which indicated the ratio of 11S/7S in different varieties was related to the accumulation of Basic subunits during seed development.关键词
