Histological and cellular research on rachis of healthy and inoculated spikes of the mutants at the different stages showed that, structure and developed tendency of cortical sclerenchyma tissue and green tissue and fibrovascular tissue in the rachis were alike between the mutants and their donors at anthesis stage, which also showed no apparent difference in the inoculated spikes'rachis between the mutants and their donors, major difference was that the mutants had less hyphae number than their donors.

对抗赤霉突变体的健康穗及接种穗的穗轴细胞组织学研究结果显示，抗性突变体与其感病亲本的花期健康穗轴在皮层厚壁组织、绿色组织及维管组织结构上基本一致，不同发育时间的变化趋势也一致；接种处理后，抗性突变体与其感病亲本的穗轴组织在各方面的变化趋势相一致，变化量也无明显差异。

The principal purpose of this study is to set up the isolation methods for diphtheria toxin expressed by genes, to purify the toxin with complete biological activities, and to make researches on its toxicities. In the experiments, the target gene was inserted into the cloning vectors--pET22b, then the vectors were introduced into host cells -BL21(DE3). The expression of the toxin was induced by addition of IPTG. The expression products were purified by His-6 label affinity chromatography. Then the diphtheria toxin expressed was transferred to PVC membrane using semidry blotter to determine the amino acid sequence of N-terminal. The "nicked" diphtheria toxin linked by disulfide bond was gained by protease hydrolysis.

为建立重组基因表达白喉毒素的分离纯化方法，制备出具有生物活性的蛋白质毒素，构建了白喉毒素表达载体pET22b-DT，并转入大肠杆菌BL21(DE3)中诱导表达，以融合表达的His-6作为标签通过亲和层析纯化；表达毒素经蛋白酶酶切后，形成了以二硫键连接的与天然结构相同的带"缺口"的白喉毒素，并测定白喉毒素对豚鼠的急性毒性和细胞毒性。
