摘要：

By employing pulsed-field gel electrophoresis we have determined the size of the rDNA cluster in wild-type yeast strains representing genera of Candida, Kluyveromyces, Pachysolen, Schizosaccharomyces and Torulaspora. Although the genome size of the examined species is similar (12.3-13.9 Mb), at least a four-fold variation has been observed between the lowest amount of rDNA repeats in P. tannophilus (28) and the highest in C. glabrata and S. poombe (> 115). In two species the rDNA cluster is represented by two loci, residing either in one (S. pombe) or two chromosomes (C. glabrata).
