| 摘 要： | 利用脉冲电泳技术研究了串珠镰孢Ｄ交配群和Ｅ交配群间及同一交配群的寄主和地区来源菌株电泳核型的相似性或多样性。结果显示，串珠镰孢Ｄ交配群菌株有９～１０条染色体，不同染色体ＤＮＡ分子量范围为０．７～６．１Ｍｂ，基因组大小约为３３．３～３７．９Ｍｂ；Ｅ效配群供试菌株分离出４～７条染色体，染色体ＤＮＡ分子量变化范围为０．７～４．８Ｍｂ，部分基因组大小约为９．０～２１．４Ｍｂ。电泳核型分析结果表明，在串珠镰

| Abstract: | Electrophoretic karyotypes of mating population D and E of Fusarium moniliforme were obtained by using pulsed field gel electrophoresis(PFGE).9?10 chromosome sized DNA,varying from 0 7?6 1 Mb,were separated from the tested isolates of mating population D and estimated genome sizes were 33 3?37 9 Mb.For the mating population E,only 4?7 chromosome sized DNAs were separated,varying from 0 7?4 8 Mb,and the partial genome sizes were estimated to be 9 0?21 4 Mb.Isolates from the same mating population had similar electrophoretic karyotypes,regardless of their host of locality,but isolates from the different mating population had dissimilar electrophoretic karyotypes. |
