Heterokaryons (hets) of Candida albicans are produced by fusing protoplasts of complementing auxotrophic strains and can be propagated continuously on minimal medium despite their tendency to assort nuclei into monokaryotic blastospores. Most monokaryons have parental-type nuclei, but some are nucl

β¦ Synopsis
Nutritionally balanced heterokaryons of the naturally diploid, asexual yeast, Candida albicans are produced by fusing protoplasts of complementing auxotrophic strains. Spontaneous unidirectional internuclear transfers of an intact gene linkage group in established heterokaryons is demonstrated. Evidence is presented that a transfer event (i) typically involves a single chromosome which is added to the resident homologues of a recipient nucleus, (ii) can occur equally well in either direction between complementing nuclei and (iii) may encourage gene conversion at transferred loci in the recipient nucleus. The bearing of these findings on application of protoplast fusion to parasexual genetic analysis of C. albicans is discussed.

A genomic library of the asexual pathogenic yeast Candida albicans was constructed in the S. eerevisiae vector YEp13. The library contains a representation of the entire genome with a probability of 99%. The expression of the genes of C. albicans in S. cerevisiae was examined and two mutations his3-
