About this newsletter:
This is the Summer 2024 issue of the SGD newsletter. The goal of this newsletter is to inform our users about new features in SGD and to foster communication within the yeast community. You can view this newsletter as well as previous newsletters, on the SGD Community Wiki.

Budget cuts from NIH continue to strain SGD's finances. Despite our efforts at reducing costs, we still have significant ongoing budgetary challenges. Donations are now critical for our work to continue.

Your generous gift to SGD will help us to continue providing essential information for your research and teaching efforts.

To contribute, please make checks payable to Stanford University, noting that "the funds should be used to support the Saccharomyces Genome Database project, under the direction of Drs. Sherlock and Cherry in the Department of Genetics, Stanford University.  Account : GHJKO, Genetics : WAZC."

Reference genome update R64.5 - still working on this one

The S. cerevisiae strain S288C reference genome annotation has been updated to include previously unannotated features. The new genome annotation is release R64.5.1, dated 2024-05-29. Note that the underlying genome sequence itself was not altered; the chromosome sequences remain stable and unchanged.

The R64.5.1 update included:

Six new open reading frames (ORFs):

New uORFs for 4 ORFs:

- A uORF is a small upstream open reading frame that precedes, and regulates downstream translation of, the major ORF. 

Move start

Various sequence and annotation files are available on SGD’s Downloads site. You can find more update details on the [Details of 2023 Reference Genome Annotation Update R64.4] SGD Wiki page.

Extend gene coordinates in GFF

The saccharomyces_cerevisiae.gff contains sequence features of Saccharomyces cerevisiae and related information such as Locus descriptions and GO annotations. The saccharomyces_cerevisiae.gff is fully compatible with Generic Feature Format Version 3, and is updated weekly.

After November 2020, SGD updated the transcripts in the GFF file to reflect the experimentally determined transcripts (Pelechano et al. 2013, Ng et al. 2020), when possible. The longest transcripts were determined for two different growth media – galactose and dextrose. When available, experimentally determined transcripts for one or both conditions were added for a gene. When this data was absent, transcripts matching the start and stop coordinates of an open reading frame (ORF) were used.

Old version: BDH2/YAL061W with longest transcripts expressed in GAL and in YPD. yal061w w2transcripts.jpg

Beginning in February 2024, SGD increased the start and stop coordinates of genes to encompass the start and stop coordinates of the longest experimentally determined transcripts, regardless of condition. This change was made in order to comply with JBrowse 2, a newer and more extensible genome browser, which requires that parent features in GFF files (genes) are larger than child features (mRNA, CDS, etc) (Diesh et al., 2023).

After February 2024: BDH2/YAL061W with increased start/stop coordinates. yal061w extendedgene.jpg

This is a standard format used by many groups. SGD uses the GFF file to load the reference tracks in SGD’s genome browser resource.

microPublications - latest yeast papers

https://www.micropublication.org

​microPublication Biology is part of the emerging genre of rapidly-published research communications. microPublications publishes brief, novel findings, negative and/or reproduced results, and results which may initially lack a broader scientific narrative. Each article is peer-reviewed, assigned a DOI, and indexed through PubMed and PubMedCentral.

Consider microPubublications when you have a result that doesn't necessarily fit into a larger story, but will be of value to others.

Latest yeast microPublications:

All yeast microPublications can be found in SGD.

Alliance of Genome Resources - Latest Release 7.2

https://www.alliancegenome.org

The Alliance of Genome Resources, a collaborative effort between SGD and other model organism databases (MODs), released version 7.2 in June 2024.

The 7.2.0 release updates the Disease pages’ Associated Alleles table and the Associated Models table:

  • Each table has a new column, Disease Qualifier, with a working filter. The qualifier describes whether an allele or model may be, for example, implicated in the onset of a disease or a model for the severity of a disease, respectively
  • In addition to the Disease Qualifier, the Associated Models table now has new columns for Condition Modifier and Genetic Modifier
  • The “Annotation Details” pop-up has expanded to include more information.
    • Alleles table: Association, Genetic Modifiers, Genetic Sex, Notes, and Annotation Type
    • Models table: Genetic Sex, Notes, and Annotation Type
  • The Associated Models table now has working filters for the Experimental Condition, Condition Modifier, and Genetic Modifier columns, including the ability to filter on relationship (e.g. induced by) as well as content (e.g. “copper”)
  • The Download files from the disease page Associated Alleles table and Associated Models table now include additional information as well.
    • New columns and information for the Associated Alleles table include: Allele Association, Genetic Entity Association, Disease Qualifier, Evidence Code Abbreviation, Experimental Conditions, Genetic Modifier Relation, Genetic Modifier IDs, Genetic Modifier Names, Genetic Sex, Notes, Annotation Type, Source URL, and Date.
    • New columns and information for the Associated Models table include: Model Type, Model Association, Disease Qualifier, Evidence Code Abbreviation, Experimental Conditions, Condition Modifiers, Genetic Modifier Relation, Genetic Modifier IDs, Genetic Modifier Names, Genetic Sex, Notes, Annotation Type, Source URL, and Date.
