The yeast deletion project, formally the Saccharomyces Genome Deletion Project, is a project to create data for a near-complete collection of gene-deletion mutants of the yeast Saccharomyces cerevisiae. Each strain carries a precise deletion of one of the genes in the genome. This allows researchers to determine what each gene does by comparing ...
Delitto perfetto (Italian: [deˈlitto perˈfɛtto]) is a genetic technique for in vivo site-directed mutagenesis in yeast. This name is the Italian term for "perfect murder", and it refers to the ability of the technique to create desired genetic changes without leaving any foreign DNA in the genome.
Synthetic genetic array analysis is generally conducted using colony arrays on petriplates at standard densities (96, 384, 768, 1536). To perform a SGA analysis in S.cerevisiae, the query gene deletion is crossed systematically with a deletion mutant array (DMA) containing every viable knockout ORF of the yeast genome (currently 4786 strains).

Gene knockout by mutation is commonly carried out in bacteria. An early instance of the use of this technique in Escherichia coli was published in 1989 by Hamilton, et al. [2] In this experiment, two sequential recombinations were used to delete the gene.
A classical strategy for generating gene deletion variants is based on double cross-integration of non-replicating vectors into the genome. Furthermore, recombination systems such as Cre-lox are widely used, mostly in eukaryotes. The versatile properties of Cre recombinase make it ideal for use in many genetic engineering strategies.
In yeast, deletion strains are frequently used to assess protein stability over time with cycloheximide chases. For example, yeast strains lacking critical degradation machinery such as chaperones, E3 ligases, and vacuolar proteins are often used to determine the mechanism of degradation for a protein substrate of interest.
Mycology is the branch of biology concerned with the study of fungi, including their taxonomy, genetics, biochemical properties, and use by humans. [1] Fungi can be a source of tinder, food, traditional medicine, as well as entheogens, poison, and infection.
Yeast artificial chromosomes (YACs) are genetically engineered chromosomes derived from the DNA of the yeast, Saccharomyces cerevisiae, which is then ligated into a bacterial plasmid. By inserting large fragments of DNA, from 100–1000 kb, the inserted sequences can be cloned and physically mapped using a process called chromosome walking .
