分别从玉米小斑病菌T、C、O三个生理小种的菌丝中提取可溶性蛋白,进行聚丙烯酰胺凝胶电泳(PAGE)和SDS聚丙烯酰胺凝胶电泳(SDS-PAGE),经多次比较试验,T、C、O小种的蛋白质图谱主带基本相同,个别带存在一定差异,而同一生理小种不同菌株间差异甚小.建议运用病原菌蛋白电泳的方法,作为小种分类、病害预测的手段之一. Soluble proteins were extracted from the mycelia of three physiological races of C. turcicum by polyacrylamide gel electrophoresis (PAGE) and SDS polyacrylamide gel electrophoresis (SDS-PAGE) The results showed that the main bands of the protein profiles of T, C and O were basically the same, but there were some differences among the individual bands, but there was little difference among different strains of the same race.It was suggested to use the method of pathogen protein electrophoresis as the classification of races, Disease prediction one of the means.
