对属于玉米大斑病菌１、２号生理小种的四个标准菌株的过氧化物同工酶和酯酶同工酶进行ＰＡＧＥ和ＩＥＦ分析研究．过氧化物同工酶扫描图谱发现１号生理小种在薄板８０ｍｍ处有明显的馒头状吸收峰（Ｇ峰），而２号小种在薄板８０ｍｍ处有一微弱吸收（Ｍ峰），紧随其后义在８５ｍｍ处出现另一微小吸收峰（Ｎ峰），可见玉米大斑病菌１、２号在生理小种的过氧化物同工酶图谱有一定的差异。酯酶同工酶扫描图谱发现，１号生理小种在薄板１３０ｍ。处有一明显的窄长吸收峰（Ｇ峰），而２号小种在此区域则无明显吸收。如果两性电解质由ｐＨ４～６换成ｐＨ３．５～１０时。２号小种在薄板７０ｍｍ处有一Ｃ峰出现，但１号小种没有出现该峰，可见玉米大斑病菌１、２号生理小种的酯酶同工酶也存在着差异，这将为探讨玉米大斑病菌毒素产生的遗传学和不同小种毒素的毒性成分间的关系奠定基础。
PAGE and IEF analysis of peroxidase isoenzyme and esterase isozyme of four standard strains belonging to the physiological races of S. Peroxidase isoenzymes scans showed that Physiological Race 1 showed obvious bread peak (G peak) at 80mm, while Race 2 showed slight absorption (M peak) at 80mm, followed by There was another slight absorption peak (N peak) at 85mm after the meaning of Yiwei, showing that there was a certain difference in the pattern of peroxidase isozymes between S. Esterase isozyme scans showed that Physiological No. 1 was on the sheet 130 m. There is a clear narrow absorption peak (G peak), while the No. 2 races in this area no significant absorption. If the amphoteric electrolyte is changed from pH4 ~ 6 to pH3.5 ~ 10. There was a C-peak at the thickness of 70mm in the race 2, but it did not appear in the race 1, indicating that there was also a difference in the esterase isozymes in the race 1 and 2 of S. turcica The relationship between the genetics of toxin blotch and the toxic components of different locust toxins was laid.
