In this dissertation, firstly, the conditions of isolation and purification of specific toxin fractions produced by Exserohilum turcicum has been studied, and a high-efficient method has been established;secondly, the toxins were analysed by UV-Vis spectrophotometry;then the effect of specific toxin on death rate of corn leaves protoplast was studied by FDA as a tinct reagent;finally, using ANS as a probe and SDS-PAGE to study the membrane protein of the corn leaves with Htl gene. In a word, the aim of the research is to search some existent evidences of the toxin binding site on protoplasmic membrane, and provide proofs for nosogenesis of specific toxin in terms of cytology and the molecular biology.

本研究对玉米大斑病菌1号小种毒素的特异性组分进行分离，建立了高效的特异性毒素分离纯化方法，并对其进行了紫外波谱分析；用荧光素双醋酸酯染色法，测定了毒素特异性组分对原生质体死亡率的影响；进而用1-苯胺基-8-萘磺酸荧光探针标记法和SDS-PAGE电泳法对特异性毒素组分与Htl基因玉米细胞互作过程中的质膜蛋白进行了研究，旨在证明Htl基因玉米细胞质膜上存在特异性毒素组分结合蛋白，为从细胞和分子生物学角度阐明毒素的致病机理提供证据。

本试验以红三叶为材料，采用盆栽试验、室内化学分析和统计分析相结合的方法，从植物营养的角度研究了土壤和施肥对红三叶产量和品质(包括饲用品质、矿质品质、保健品质)的效应。

For example, we study the properties of the"centroid curve" and the"auxiliary curve", and identify two planes in which these two curves are defined respectively; we also use the idea of homotopy method to prove a fact that the orbit of a differential system has no triple contact point with the line we considered. Another key technique, which we use several times, is deformation argument.
