应用薄层等电聚焦电泳,分析了国内外不同地区、不同寄主47株白僵菌菌株的酯酶同工酶谱;依据各谱带等电点和扫描距离,确立了酶谱的三个区带。通过聚类分析和酯酶型分类,证实不同寄主的白僵菌酯酶同工酶谱差异显著,同一寄主而不同地区的白僵菌酯酶同工酶谱有一定的群体差异。与垂直平板凝胶电泳比较,薄层等电聚焦电泳用于白僵菌酯酶同工酶分析,分辨率较高。 By isoelectric focusing electrophoresis, the isozyme patterns of 47 isolates of Beauveria in different regions of China were analyzed. Based on the isoelectric point and scanning distance, three regions of the enzyme spectrum band. Through cluster analysis and esterase classification, it was confirmed that isoenzyme isoenzyme patterns of Beauveria bassiana from different hosts were significantly different. There was a certain population difference in isoenzyme isoenzyme pattern of Beauveria bassiana in the same host and in different areas. Compared with the vertical plate gel electrophoresis, TLC isoelectric focusing was used to analyze the isoenzyme of Beauveria bassiana, with higher resolution.
