The mating of yeast, also known as yeast sexual reproduction, is a biological process that promotes genetic diversity and adaptation in yeast species. Yeast species, such as Saccharomyces cerevisiae (baker's yeast), are single-celled eukaryotes that can exist as either haploid cells, which contain a single set of chromosomes, or diploid cells ...

Budding yeast cells are exquisitely able to project a shmoo towards the source of a pheromone gradient, allowing them to grow towards a potential mating partner.

2024年10月18日 · In the world of cellular biology, shmoo formation in yeast is a fascinating process that highlights the complexity and adaptability of these simple organisms. This morphological change occurs during mating, allowing yeast …

2010年4月19日 · In today's new study, researchers from Imperial College London, Université de Montréal, McGill University and the University of Edinburgh determined that a yeast cell's decision to mate is controlled by a chemical change on a single protein.

The intracellular signal transduction pathway by which the yeast Saccharomyces cerevisiae responds to the presence of peptide mating pheromone in its surroundings is one of the best understood signaling pathways in eukaryotes; much has been learned from the application of classical and molecular genetics, biochemistry and cell biology.

2023年1月15日 · Haploid yeast cells exchange pheromone signals, stop in G1 phase and undergo polarized growth (shmooing). Upon cell-cell contact, the cell wall is digested and the plasma membranes merge, thus forming a diploid zygote. Interaction between mating-type specific proteins prevents refertilization.

2006年9月1日 · A useful model system to study MT-dependent forces before nuclear fusion, or karyogamy, is the mating pathway of budding yeast. Dynamic MTs are guided to the mating projection (shmoo tip) when plus-end-binding proteins interact with polarized actin microfilaments.

2014年8月7日 · To mate, the yeast Saccharomyces cerevisiae needs to shmoo — to generate a projection that reaches out to a nearby yeast of the opposite sex, until the yeast cell is shaped like the Al Capp cartoon character. And to shmoo yeast …

2012年11月11日 · In yeast mating projection (shmoo) formation, a morphorgenesis process in which no evident diffusion barrier has been found (although the septin structure at the base of the projection may potentially act in this manner), endocytosis and exocytosis could play critical roles in both maintaining polarity and expanding the membrane to produce the ...

2006年3月1日 · Many features of apoptosis have been demonstrated in yeast, such as cell shrinkage, chromatin condensation along the nuclear envelope, nucleus and DNA fragmentation (detected by the terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay), externalization of phosphatidylserine in the plasma membrane, decrease in mitochondrial ...
