摘　　要：用脉冲电泳对四种假丝酵母及各自的有性型,包括Candida guilliermondii—Pichia guilliermondii, Candida krusei—Issatchenkia orientalis, Candida naganishii—Debaryomyces nepalensis和Candida valida—Pichia membranaefaciens,进行了分子核型比较分析, 发现每对无性型-有性型酵母菌均具有相同或相似的染色体DNA分子带型, 而各对之间却具有显著差异,显示了脉冲电泳核型分析在寻找及确证酵母菌无性型-无性型关联中的应用价值。Comparative molecular karyotype analysis by using pulsed field gel electrophoresis (PFGE) showed that the type strains of each of the following established anamorphteleomorph counterparts: Candida guilliermondiiPichia guilliermondii, Candida kruseiIssatchenkia orientalis, Candida naganishii Debaryomyces nepalensis and Candida validaPichia membraefaciens had similar or identical chromosomal DNA banding patterns. This result indicates the potential usage of electrophoretic karyotyping in the establishment and confirmation of anamorphteleomorph connections in yeasts.
