摘　　要：本研究旨在分析热休克蛋白90(HSP90)基因的保守性,并为寻找新的HSP基因,探索HSP90的应用提供理论数据。利用CODEHOP设计简并引物,采用PCR方法克隆鲫鱼的HSP90序列,并将扩增的序列克隆到pMD18-T载体中构建克隆载体后进行测序,再将测序结果通过BLAST进行同源性比对并构建系统进化树。结果显示,鲫鱼与鲤鱼的同源性为99%;与斑马鱼的同源性为92%。本试验设计出的引物简并度较低,Tm值的修改较为灵活,产物特异性强,为研究鲫鱼的功能基因提供基础保障,并为热休克蛋白在进化上的保守性研究奠定理论基础。The purpose of this study was to analyze the conservative of heat shock protein 90 （HSP90） gene,and provide theoretical data for the new HSP gene by exploring the application of HSP90. Using CODEHOP to design the degenerate primers,cloning Carassius auratus HsPg0 se- quence by PCR,and then the sequence was cloned into pMD18-T vector to construct clone vector after sequencing. Then sequencing homology were compared by BLAST and phylogenetic tree was constructed. The results showed that the homology was 99% between Carassius auratus and Cyprinus carpio ~ And the homology was 92% between Carassius auratus and Danio rerio. The degeneracy of primers designed in this study was low, the modification of Tm value was more flexible, and the product had high specificity. The study provided basis guarantee for research of Carassius auratus function genes,and laid the theoretical foundation for the study of heat shock proteins conservative in evolution.
