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。

The main results were showed as follows:Through screen and identification of morphology in M_2 and M_3, respectively, the mutants with mutative traits of plant were found. In which, 11 mutations were leaf variations, including light-green leaf, deep-green leaf, durative yellowish leaf, temporary yellowish leaf, inlaid yellowish leaf, wrinkly leaf, smooth-edged curly leaf, splitting-shaped curly leaf, peduncular-shaped leaf, round leaf and larger leaf, 12 were mutations on plant type, including excessive branches, lacking branches, highness, dwarf-like, erect posture, reclinate posture, strong stalk, slender stalk, tufty branches, wrinkled plant, purple stalk and hair-covered plant, 14 were flower variations, including dense flowers, light-yellow petals, white petals, white-mosaic petals, wrinkled petales, back-rolled petals, narrow petals, larger petals, smaller petals, apetalous flowers, variable-numbered petals, fertile pistil protraction, sterile pistil protraction and multi-anther, and 5 were physiologic mutants, including genic male sterile, cytoplasmic male sterile, bud-dead, and early and later bloom.

主要结果如下：通过田间M_2筛选和M_3重复鉴定，在田间农艺性状方面共获得浅绿叶色、深绿叶色、转绿黄化叶、持续黄化叶、边缘黄化叶、皱缩叶、光叶型卷叶、裂叶型卷叶、薹叶形叶、宽圆叶和大叶等11种不同的叶部性状突变体；同时还筛选到多分枝、少分枝、高杆、矮杆、株型紧凑、株型松散、粗茎、细茎、丛生分枝、整株皱缩、紫茎、整株被毛等12种植株性状突变体，密花、浅色花瓣、白色花瓣、白斑花瓣、皱瓣、卷瓣、窄瓣、大瓣、小瓣、无瓣、花瓣数目不定、可育型柱头外露、不育型柱头外露和多雄蕊等14种花器性状突变体，以及细胞核雄性不育、细胞质雄性不育、死蕾、早花和迟花等5种生理性状突变体。

A kind of virus particles were observed in cytoplasm of sampled ill sea cucumber tissues which were sampled from sick sea cucumbers with ulcerous skin and swollen mouth from their farming ponds at the beginning of 2005. The particles were covered with a bilayer envelops, shaped in globular with its size 100-200 nm in diameter. The same virus was isolated from cultured sea cucumbers with disease from different time and sites, and then infected the healthy sea cucumber. sea cucumber appeared the phenomenon such as ulcerous skin and swollen mouth and the same virus was isolated from infected sea cucumbers.

本章从患病刺参中分离出了2株对刺参具有感染能力的细菌，经鉴定1株为弧菌科弧菌属Vibrio sp和1株为弧菌科施万氏菌属Shewanella sp；在患病刺参的触手、肠和呼吸树等组织的细胞质中，检出了球形、具双层囊膜、直径大约为100-200nm的病毒粒子利用分离的病毒进行人工感染实验，刺参可以产生与自然发病刺参相同的症状，显示了分离的病毒对刺参具有一定的感染性。

Two mode of plastid inheritance, uniparental maternal and biparental inheritance, were discovered in angiosperms at the beginning of this contury, and our knowledge of the mode and cytological basis of cytoplasmic inheritance, esp. plastid, has been improved in many respects following the new cytological and molecular techniques, eg. electron microscopy, DNA fluorescence and RFLP.
