Sexual differentiation in fission yeast

Trends in Genetics, 1990
The regulation of sexual reproduction in yeast constitutes the highest level of differentiation observed in these unicellular organisms. The various ramifications of this system involve DNA rearrangement, transcriptional control, post-translational modification (such as protein phosphorylation) and receptor/signal processing.

Transcriptional silencing in fission yeast

Journal of Cellular Physiology, 2000
In eukaryotes, epigenetic events govern diverse processes, ranging from gene expression to other aspects of global chromosome architecture essential for preserving the integrity of the genome. Transcriptional silencing at the mating-type locus, centromeres, and telomeres of the fission yeast is regulated by epigenetic mechanisms.

Oxygen toxicity in a fission yeast

Journal of Cellular Physiology, 1971
AbstractContinuous exposure of synchronous cultures of Schizosaccharomyces pombe to 2.0 atmospheres oxygen beginning at any point in the first two‐thirds of the cell cycle prevented subsequent cell division. Similar exposure during the last one‐third of the cell cycle did not prevent cell division.

Analysis of chromatin in fission yeast

Methods, 2004
The use of fission yeast as a model system for studies of chromosome biology has contributed to several key advances in the last few years. The structure of its large complex centromeres and composition of its transcriptionally silent heterochromatin resemble those of metazoa.

Chromatin Immunoprecipitation in Fission Yeast

2011
A tremendous amount of information regarding the nature and regulation of heterochromatin has emerged in the past 10 years. This rapid progress is largely due to the development of techniques such as chromatin immunoprecipitation or "ChIP," which allow analysis of chromatin structure. Further technological advances such as microarray analysis and, more

Ribosome Numbers in a Fission Yeast

Nature, 1965
THERE is a need for a more confined and precise use of the word ribosome. It would clarify molecular biology if the word were reserved for particles in the cell which measure 100 A–300 A in diameter, are composed of RNA and protein, and have been shown to be active as sites for the synthesis of proteins.

Electron Microscopy of Fission Yeast

Cold Spring Harbor Protocols, 2017
Electron microscopy (EM) can provide images of cells with a spatial resolution that significantly surpasses that available from light microscopy (LM), even with modern methods that give LM “super resolution.” However, EM resolution comes with costs in time spent with sample preparation, expense of instrumentation, and concerns regarding sample ...

Centromeric chromatin in fission yeast

Frontiers in Bioscience, 2008
A fundamental requirement for life is the ability of cells to divide properly and to pass on to their daughters a full complement of genetic material. The centromere of the chromosome is essential for this process, as it provides the DNA sequences on which the kinetochore (the proteinaceous structure that links centromeric DNA to the spindle ...

Fission yeast on the brink of meiosis

BioEssays, 2000
The fission yeast Schizosaccharomyces pombe (S. pombe) is now well established as a versatile genetic model organism. It is widely used to analyse the basic eukaryotic cell cycle during vegetative growth and it is also well suited to studies on the elementary processes of sexual reproduction, including intercellular communication and signal ...

Tetrad Dissection in Fission Yeast

2018
Tetrad dissection is a powerful tool in yeast genetics that allows the analysis of products of a single meiosis. With just a few tetrads, it is possible to determine linkage, identify unique phenotypes associated with double mutants, or assess specific meiotic defects. Strains are crossed on nitrogen-limiting medium for 3 days.
