  Yeasts: Saccharomyces, Cryptococcus, Candida   (Site not responding. Last check: 2007-10-13)
Yeasts are fungi that grow as single cells, producing daughter cells either by budding (the budding yeasts) or by binary fission (the fission yeasts).
Yeasts grow typically in moist environments where there is a plentiful supply of simple, soluble nutrients such as sugars and amino acids.
budding yeast used for bread-making, where the carbon dioxide produced by growth in the dough causes the bread to rise.

 The Budding Yeast Cell Cycle   (Site not responding. Last check: 2007-10-13)
Although the complexity of the regulatory network increases tremendously, the basic mechanism is highly conserved from yeast to man.
Budding yeast (Saccharomyces cerevisiae) is the most well-studied model organism for cell cycle research.
We show in the budding yeast website and the companion paper that a computational model, built on the consensus picture of regulatory network derived from reductive biochemical studies and genetic manipulations, is largely successful (predicting 120 out of 133 cases) in explaining the phenotypes of currently characterized mutants of the regulatory system.

 Budding Yeast
Saccharomyces cerevisiae, the budding yeast, is the common yeast used in baking ("baker's yeast") and brewing ("brewer's yeast").
Budding yeast can live with either two genomes (diploid) or one (haploid).
In either case, it reproduces by forming buds (hence the name) by mitosis.

This study analyzes the biological importance of Mcm2p phosphorylation in budding yeast.
Yeast cells carrying the mutant allele mcm2-12SA grow normally and mcm2-12SA fully complements a defect in chromosomal mcm2, but mcm2-12SA is synthetically lethal with temperature-sensitive dbf4-4 and it enhances the temperature sensitivity of dbf4-1, -2, -3 or -5.

 Kinetic Analysis of a Molecular Model of the Budding Yeast Cell Cycle — CellML
However, budding yeast are unusual in that they divide asymmetrically.
S and M phases are completed before the bud can grow as large as the mother cell and consequently, budding produces a large mother cell and a small daughter cell.
A second anomaly of yeast budding is that the cells pass through the S and M phases of the cell cycle without their chromatin condensing into discrete chromosomes.

 BioMed Central | Abstract | Characterization of the minimum domain required for targeting budding yeast myosin II to ...
Budding yeast has a single myosin II protein, named Myo1.
We show that the MLD is a small region in the centre of the tail of Myo1 and that it is both necessary and sufficient for localisation of Myo1 to the yeast bud neck, the pre-determined site of cell division.
Our results define the intrinsic determinant for the localization of budding yeast myosin II and show it to be an oligomer of tentatively 3 monomers.

 Sloan-Kettering - Projects: CDK Activation in Fission Yeast
Metazoans and budding yeast each have a single CAK, but they are not homologous to one another.
In contrast, fission yeast has two CAKs: the Mcs6 complex, which is homologous to the metazoan CAK (Cdk7); and Csk1, which is homologous to budding yeast Cak1.
Remarkably, the fission yeast Schizosaccharomyces pombe contains two CAKs — one homologous to Cdk7 of higher eukaryotes and one superficially similar to budding yeast Cak1.

 Cell cycle control of septin ring dynamics in the budding yeast -- Cid et al. 147 (6): 1437 -- Microbiology
Rho1 is essential for the proper establishment of bud emergence at a stage subsequent to septin assembly at the pre-bud neck.
During bud growth throughout S, G2 and M phases of the cell cycle, the septin ring gradually expands to conform the neck-spanning structure that covers both mother and daughter sides of the constriction, appearing under fluorescence microscopy as the hourglass-shaped ring that is characteristic of metaphase- and anaphase-arrested cells.
