Despite the variation in the predicted time of divergence, phylogenetic analysis, and experimental evidence, it can be shown that the gene sequences of Sz. pombereproduces by fission, a process similar to that used by higher eukaryotic cells. However, fission yeast is taxonomically and as evolutionarily distinct from budding yeasts as it is from humans. pombeis a free-living fungus, classified with ascomyctes such as S. Lindner who isolated yeast from millet beer of East Africa and gave it the name “pombe” from the Swahili word for beer. pombe) is a yeast found in sugar-containing fermentations of alcohol involved in the production of beer in subtropical regions the yeast was first described in 1893 by P. *Address all correspondence to: General features of Schizosaccharomyces pombe

Fission yeast was defined as a micro-mammal because it shares many molecular, genetic, and biochemical features with cells of higher eukaryotes in mRNA splicing, post-translational modifications as N-glycosylation protein, cell-cycle regulation, nutrient-sensing pathways as the target of rapamycin (TOR) network, cAMP-PKA pathway, and autophagy. pombe can be genetically manipulated using methods such as mutagenesis or gene disruption by homologous recombination. The fission yeast has a doubling time of 2–4 hours, it is easy and inexpensive to grow in simple culture conditions, and can be maintained in the haploid or the diploid state. pombe is a rod-shaped cell that grows by apical extension it divides along the long axis by medial fission and septation. pombe), or fission yeast, is an ascomycete unicellular fungus that has been used as a model system for studying diverse biological processes of higher eukaryotic cells, such as the cell cycle and the maintenance of cell shape, apoptosis, and ageing.
