Abstract

Pulsed-field gel electrophoresis techniques were used to study chromosome-sized DNA molecules of C. albicans. Chromosome-sized DNA of two strains of Candida albicans has been resolved into 8 bands by orthogonal-field-alternation gel electrophoresis (OFAGE). Six bands were observed in chromosomal preparations of C. albicans using field-inversion gel electrophoresis (FIGE). Differences in the electrophoretic mobilities of bands of the strains of C. albicans examined suggests that chromosome-length polymorphisms exist and make it difficult to correlate the banding patterns among strains. These correlations were facilitated, however, by assignment of C. albicans chromosomes by hybridization using a collection of cloned DNA probes specific for each of the 8 observed bands. Southern blotting showed that the 6 FIGE bands consisted of 4 singlets and 2 comigrating doublets, accounting for the 8 bands observed by OFAGE analysis. The agreement between OFAGE and FIGE analysis suggests that the C. albicans haploid genome contains a minimum of 8 chromosomes.
