The fission yeast genome can thus be said to be 'less redundant' than that of budding yeast this has been empirically known, but now we can put a number on redundant genes. Using the same type of comparison in budding yeast, 5,061 genes are unique while 716 fall into groups that have two or more members. pombe genome itself, while the remaining 361 genes' products are distributed among groups of proteins that have two or more members. 'All against all' sequence comparisons indicate that 4,515 genes among the total 4,876 have no homologs within the S. pombe will for some time to come hold an honorable position as the eukaryote with the fewest genes.Īround two-thirds of the predicted fission yeast proteins have homologs in both budding yeast and nematode, and only 14% are found in neither budding yeast nor nematode. It is a matter of judgment whether this number seems small or large for the task of creating a eukaryotic cell from molecular components in any case, S. As the bacterium Streptomyces coelicolor has 7,846 genes, two conclusions that can be drawn are that a free-living eukaryote can be constructed with fewer than 5,000 genes, and that it may even need fewer genes than some prokaryotes. This 'lower' eukaryotic unicellular organism has 4,824 predicted genes, the smallest number recorded for a eukaryote and significantly fewer than the 5,570-5,651 genes predicted for budding yeast. pombe holds no hint of a large-scale genomic duplication of the type that occurred in budding yeast and many other organisms there is a small (approximately 50 kilobase) duplication near the telomere, however.
