采用线性梯度SDS-PAGE分析芸薹属4个种17个品种(系)的种子贮藏蛋白亚基组成,表明种子贮藏蛋白比较复杂,共有58条带,分子量范围是8000~300000D,不同种不同品系带型不同,种间差异主要表现在8000~70000D之间,品种(系)的差异主要在70000~300000D之间,相似度指数也表现出同种内不同的品种之间相似度高,种内品种间相似度大于种间。
A linear gradient SDS-PAGE analysis of the seed storage protein subunits of 17 cultivars (lines) of four Brassica species indicated that the storage proteins of the seeds were rather complicated with a total of 58 bands with a molecular weight range of 8000-300000D. Different strains Different types of bands, the main differences between species in the 8000 to 70000D between varieties (lines) mainly in the 70000 ~ 300000D between the similarity index also showed the same species within the different varieties of high similarity, intraspecific The similarity between varieties is greater than that between species.
