摘要 CHEF Ⅲ型脉冲电泳仪是微生物种类鉴定、DNA大分子分离等基础科学研究中一个不可或缺的重要工具。该仪器可以快速、高效、准确地分离200 kb到6 Mb的DNA分子。因此,在染色体数目及染色体大小的确定、核型分析、遗传图谱分析、同源性检测分析等方面有关键性的作用。然而在实验过程中要使DNA分子完全、有效地分离,得到清晰、高效的条带却并非易事。本实验基于这些问题,经过一系列的探索研究,找到了稻瘟病菌及分子量标准酵母菌染色体分离所需要的最适条件,该条件能为分离其他真菌染色体提供借鉴与参考。 Pulsed field electrophoresis CHEF Ⅲ system separates large and small DNA fragments with better resolution,speed and accuracy than initial pulsed field methods.DNAs from 200 kilobases(Kb) to over 6 megabases(Mb) may be effectively resolved.Thus it is a very useful tool for the identification of chromosome number and size,electrophoretic karyotyping,genetic mapping,and homogeneity analysis.But as a matter of fact,it is difficult to get the better resolved bands in experiments.So this study describes some efforts in finding the optimal parameters in separating the chromosomes of magnaporthe oryzae,sccharomycete pombe and sccharomycete serevisiae by using CHEF Ⅲ system.These parameters might also be useful for separating chromosomes of other fungi.
