Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 1992
In recent years there has been increasing interest in antimutagenesis, and studies have been done using both prokaryotic and eukaryotic systems. In eukaryotic systems the first studies were performed with different strains of Schizosaccharomyces pombe. In particular, caffeine and L-methionine were investigated.

Yeasts are unicellular fungi that reproduce by the process of budding in which daughter cells are produced from parents by outpouching of the cell membrane and wall, migration of cytoplasm into the new structure thus formed, and then separation from the parent cell.

The Saccharomyces OLE1 gene encodes the intrinsic membrane-bound Δ-9 fatty acid desaturase. OLE1 expression is regulated at the levels of transcription and mRNA stability by nutrient fatty acids and molecular oxygen. Its transcription is controlled through two distinct promoter elements, the fatty acid response element (FAR) region, and a downstream ...

Yeast, 1997
Haustorium-mediated predation was observed in seven yeast species. Arthroascus javanensis, Botryoascus synnaedendrus, Guilliermondella selenospora, Saccharomycopsis fibuligera, and three hitherto unknown species penetrate and kill other yeasts. These yeasts share an unusual requirement for organic sulphur. One isolate recovered from Australian Hibiscus

The FASEB Journal, 1989
The three families of double‐stranded RNA (dsRNA) viruses and two families of retroviruses (retrotransposons) of the yeast Saccharomyces cerevisiae are all transmitted between cells only by cell fusion, probably reflecting the high frequency of mating of yeast cells in nature. One dsRNA virus

ON different occasions, when studying the classification of yeasts, I have been able to appreciate how little consistency there is in the taxonomic characters in use. Recently, I have met with fresh anomalies which, in my opinion, make a complete revision of the present system of classification of yeasts unavoidable.

Yeast, 1987
Significant progress has been made toward understanding the roles played by conserved centromere DNA sequences in both mitotic and meiotic chromosome segregation. We are just beginning to formulate a picture of what a yeast kinetochore actually looks like and what components other than CEN DNA are necessary for function.

Publisher Summary This chapter discusses the recent progress on the structure and activities of the yeast nucleus. The chapter focuses on budding yeasts and concentrates on Saccharomyces cerevisiae. This organism is currently much in favor because it is a eukaryote that can be grown and analyzed genetically with the same ease as bacteria.

IN addition to the four strains of Saccharomyces cerevisiae and one strain of Saccharomyces delbrueckii that form asci with more than four spores per ascus1, I have found eight other strains of Saccharomyces cerevisiae that are able to form asci with five, six, seven, eight and nine smooth, round ascospores. One of these strains was obtained some years
