The possibility of genetic identification of mutations in asporogenic yeast by the technique of intrageneric fusion of yeast protoplasts of Candida tropicals and Saccharomyces cerevisiae has been demonstrated for Candida tropicals strains G5-9 (Ade- Leu-) and G32-4 (Leu-). The mutations to auxotrophy ade- in the strain G5-9 and leu- in G32-4 of Candida tropicals are allelic to ade2 and leu1 mutations in the genes of Saccharomyces cerevisiae yeast. The allelic character of adenine auxotrophy mutation in Candida tropicals and ade2 mutation in Saccharomyces cerevisiae is confirmed by the absence of AIR-carboxylase activity in cellular extract from the strain G5-9.
