SGD Newsletter, Summer 2024

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.

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.

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.

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. We are seeing a strong set of microPublications come through the database and are glad for this venue to publish 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.
