Abstract

A multiply auxotrophic strain, hOG45, was derived from Candida albicans ATCC 10261. Prototrophic revertants of this multiple auxotroph were selected after mutagenesis. These prototrophic revertants were distinguishable from the original prototroph, ATCC 10261, because of their mitotic instability. They gave rise to auxotrophic derivatives which displayed one or more of the auxotrophic requirements characteristic of hOG45. Two of the auxotrophic requirements, those for adenine and methionine, frequently reappeared together in the auxotrophic derivatives of the prototrophic revertants. This apparent linkage of ade and met was confirmed by protoplast fusion analysis of the original auxotroph. These data indicate that C. albicans ATCC 10261 is diploid, the multiple auxotroph h0G45 is homozygous for recessive auxotrophic alleles, the prototrophic revertants are multiple heterozygotes, the auxotrophic derivatives are homozygotes produced by mitotic crossing-over, and the association between the ade and met alleles is due to linkage.
