S. cerevisiae was the first eukaryotic genome to be completely sequenced. [55] The genome sequence was released to the public domain on April 24, 1996. Since then, regular updates have been maintained at the Saccharomyces Genome Database. This database is a highly annotated and cross-referenced database for yeast researchers.
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 .
The first free-living organism to have its genome completely sequenced was the bacterium Haemophilus influenzae, in 1995. In 1996 Saccharomyces cerevisiae (baker's yeast) was the first eukaryote genome sequence to be released and in 1998 the first genome sequence for a multicellular eukaryote, Caenorhabditis elegans, was released.
[3] [4] [5] The genome of the extensively researched yeast Saccharomyces cerevisiae contains approximately 12 Mbp and was the first completely sequenced eukaryotic genome. [6] Due to their compact size fungal genomes can be sequenced with less resources than most other eukaryotic genomes and are thus important models for research. [7]

The Saccharomyces Genome Database (SGD) is a scientific database of the molecular biology and genetics of the yeast Saccharomyces cerevisiae, which is commonly known as baker's or budding yeast. [1] Further information is located at the Yeastract curated repository.
An autonomously replicating sequence (ARS) contains the origin of replication in the yeast genome. It contains four regions (A, B1, B2, and B3), named in order of their effect on plasmid stability. The A-Domain is highly conserved, any mutation abolishes origin function.
The second yeast species to have its genome sequenced was Schizosaccharomyces pombe, which was completed in 2002. [108] [109] It was the sixth eukaryotic genome sequenced and consists of 13.8 million base pairs. As of 2014, over 50 yeast species have had their genomes sequenced and published.
