View source for Summary of Chromosome Sequence and Annotation Updates

As new data become available, SGD curators update the systematic sequence and its annotation. This table summarizes the sequence and/or annotation updates made for each chromosome, since the intitial release on 1996-07-31.

Select the chromosome number to retrieve the corresponding Chromosome History page, which provides details on all the updates for that chromosome. Current and past versions of the sequence and annotation are also available on SGD's [https://www.yeastgenome.org/downloads Download site] and at [https://www.ncbi.nlm.nih.gov/genome/?term=txid4932 NCBI].

If you are aware of additional sequence or annotation changes that should be made to the reference sequence (S288C), please [mailto:sgd-helpdesk@lists.stanford.edu send a message] to SGD curators. At this time, SGD does not record sequence variation between S288C and other strains of Saccharomyces cerevisiae. See the [[Systematic_Sequencing_Table|Systematic Sequencing Project]] page for more information about the reference sequence.
