摘要: 应用非变性的梯度聚丙烯酰胺凝胶电泳、SDS线性梯度聚丙烯酰胺凝胶电泳、聚丙烯酰胺和琼脂糖凝胶电聚焦分析了种子形态近似但茎生长习性不同(一个直立、一个缠绕)的两个菜豆品种的种子蛋白,结果表明它们的种子蛋白在电荷和分子量组成上都有显著差别。尤其以SDS电泳谱差别最大,种子系由北京市种子公司提供。总共33种亚基,两个品种共有的仅13个左右。因此我们提议进行菜豆品种鉴定,最好用SDS线性梯度聚丙烯酰胺凝胶电泳。本文首次报道菜豆种子蛋白有高分子量亚基存在。在较低分子量范围(10-25千道尔顿)存在变异,并可用在品种鉴定上。

Abstract: Seed proteins of two cultivars of common bean(Phaseolus vulgaris)which share same seed morphology but different habit of shoot(one is erect,another is voluble)were analysed by using non-denaturating gradient polyacrylamide gel electrophoresis,SDS gradient polyacrylamide gel electrophoresis,polyacrylamide and agarose gel electric focusing.A considerable difference of both electric charge and molecular weight of seed proteins between two cultivars has leen found,especially,in protomers shown by SDS electrophoresis.Based on the fact that only 13 subunits are shared by two cultivars among total 33 bands,we suggested that SDS gradient polyacrylamide gel electrophoresis may be the most valuable in cultivar identification of common bean.Some new subunits which have their molecular weight higher than 100K and a variation occured in low molecular weight bands in bean proteins have been reported.
