Mutagenesis in Saccharomyces Cerevisiae
1982Publisher Summary This chapter discusses the mutagenesis in Saccharomyces cerevisiae and compares it with what is known about the same process in E. coli. It also discusses the experimental systems available for mutation research in bakers' yeast, the result of investigations concerning induced and spontaneous mutagenesis in nuclear and ...

Saccharomyces Marxianus Hansen
Antonie van Leeuwenhoek, 1947Zygosaccharomyces Marxianus andSaccharomyces macedoniensis belong to the same species. This species is met with in the haplophase (Z. Marxianus) as well as in the diplophase (S. macedoniensis). It was possible to bring this yeast from the haplophase into the diplophase and vice versa.

Postmeiotic segregation in Saccharomyces
Molecular and General Genetics MGG, 1971Diploid monohybrids of adenine 8 alleles were constructed to permit visual detection of meiotic gene conversion. In addition to the 3+:1 m and 1+:3 m tetrads routinely encountered, aberrant segregations comparable to the 5+:3 m and 3+:5 m patterns detected in octad ascomycetes were observed.

Mitochondrial Distribution in Saccharomyces
Nature, 1953GENETICAL experiments by Ephrussi and co-workers1 have adequately demonstrated the existence of extra-chromosomal factors determining the cytochrome oxidase and succino-dehydrogenase activities of yeast clones analysed by them. A particulate nature was ascribed to these factors, and their identity with the mitochondria was suggested in view of the well-
