Conversion of Wine Strains of Saccharomyces cerevisiae to Heterothallism.
A general method to convert homothallic strains of the yeast Saccharomyces cerevisiae to heterothallism is described which is applicable to genetically well-behaved diploids, as well as to strains that sporulate poorly or produce few viable and mating-competent spores. The heterothallic (ho) allele was introduced into three widely used wine strains through spore x cell hybridization. The result...
متن کاملHeterothallism in Saccharomyces rouxii.
Over the years a large number of osmophilic yeasts have been isolated from honey, sirups, and highly salted fermented foods of the Orient. AMany have been considered as new species by the persons who isolated them. Strains vary from one another by minute differences in physiology and morphology. The osinophilic yeasts were formerly classified in the subgenus Zygosaccharomyces, a subdivision of ...
متن کاملGlycolysis mutants in Saccharomyces cerevisiae.
Mutants have been isolated in S. cerevisiae with the phenotype of growth on pyruvate but not on glucose, or growth on rich medium with pyruvate but inhibition by glucose. Screening of mutagenized cultures was either without an enrichment step, or after enrichment using the antibiotic netropsin (Young et al. 1976) or inositol starvation (Henry, Donahue and Culbertson 1975). One class of mutants ...
متن کاملCharacterization of Saccharomyces cerevisiae ubiquinone-deficient mutants.
Ubiquinol (QH2) is a lipid-soluble molecule that participates in cellular redox reactions. Previous studies have shown that yeast mutants lacking QH2 are hypersensitive to treatment with polyunsaturated fatty acids (PUFAs) indicating that QH2 can function as an antioxidant in vivo. In this study the effect of 1 mM linolenic acid on levels of Q6 and Q6H2 is assessed in both wild-type and respira...
متن کاملIsolation and Characterization of Saccharomyces cerevisiae Mutants
Aculeacin A is a lipopeptide that inhibits ,B-glucan synthesis in yeasts. A number of Saccharomyces cerevisiae mutants resistant to this antibiotic were isolated, and four loci (ACRI, ACR2, ACR3, and ACR4) whose products are involved in the sensitivity to aculeacin A of yeast ceils were defined. Mutants containing mutations in the four loci were also resistant to echinocandin B, another member ...
