About this newsletter:

This is the January 2005 issue of the quarterly 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.

Other relevant URLs mentioned in this newsletter are also at the bottom of the page. As always, please contact SGD with any comments or suggestions at:

References for information on Locus Page

The Locus Page has been updated to display the references that have been used as citations for the Description, Name Description, and Gene Product. If references are available, a 'View References' link will be displayed on top of the locus pages and a citation number will be listed after the information. These references, along with the references used in the Summary Paragraph, are listed at the bottom of the Locus page.

New features added to Advanced Search tool

The Advanced Search tool (previously called "Chromosomal Features Search") provides an easy way to generate lists of genes based on a variety of criteria. For example, you can retrieve all genes known to be involved in meiosis, all mitochondrial proteins within a certain molecular weight, all uncharacterized ORFs, etc. We recently added new search options to this tool, including interaction and expression data as well as open reading frame classifications (Dubious, Verified, Uncharacterized).

Files for computational predictions available

Results from two studies ( Troyanskaya et al. (2003) PNAS 100:8348-53 and Lee et al. (2004) Science 306:1555-8) that predict functional interactions between genes have been added to the SGD ftp site.

SGD's paper in 2005 NAR Database Issue

The 2005 Nucleic Acids Research Database issue is now available. This issue includes a paper by the SGD staff describing the following new tools at SGD:

  • Fungal BLAST (for nucleotide and protein searches against fungal sequences available at GenBank)
  • Model Organism BLASTP Best Hits (for links to curated information about sequences conserved in other organisms)

New options for Batch Download Tool

The Batch Download Tool has been updated so that Gene Ontology (GO) annotations can be downloaded for a list of standard gene names or systematic names. The GO annotations can be downloaded simultaneously with DNA sequences, protein sequences, and chromosomal coordinate information for the same list of gene games or systematic names. In addition, links to view "Flanking Features" have been added to the "Maps & Displays" pull-down menu on the Locus Page and Gene/Sequence Resources so that neighboring chromosomal features can be viewed and downloaded.

New features on Locus Page

Several new links and features have been added to the Locus Page:

An "Expression Summary" histogram summarizes the number of microarray experiments (samples) in which the expression changed for that ORF. This histogram can be found in the lower right hand corner of the Locus Page under the "Functional Analysis" pull-down menu. It is a hyperlink to the Expression Connection summary page.

Links to view ATCC/WashU Clones in Gbrowse are available from the "Maps & Displays" pull-down menu.

Links to GPM DB, a database summarizing mass spec data, are available from the "Protein Info & Structure" pull-down menu. Thanks to Ron Beavis for helping set up the links.

Expansion of our literature search

In response to comments received in the SGD survey taken at the YGM meeting this summer, SGD is in the process of expanding its literature search to add more relevant papers to the database. As a result, you may notice more references in the Literature Guide of the Locus Pages. We are in the process of curating these new references and deleting any that are not relevant. Please feel free to alert us to any problems that you notice.

Information about lab strain backgrounds

SGD has created a Lab Strains summary page describing strains commonly used by yeast researchers, such as S288C, SK1, Sigma 1278B and W303. We will continue to add information on genotypes and important phenotypes for these backgrounds and others. If you have information that should be included, please send an e-mail with the information and a reference, if possible, to

Coming Soon: Genome Snapshot

In response to our users' requests, we are creating a web display to show an overview of the state of the genome, a Genome Snapshot. This page will summarize the status of the genome and will be updated in real time based on the existing data. A graphical view will show the distribution of ORFs by status: Verified, Uncharacterized, or Dubious. A table will show the number of each type of feature (Verified ORFs, tRNA, ARS, etc.) present on each chromosome. Bar charts will show the distribution of genes annotated to a set of high level GO terms. We will make an announcement on our home page when the Genome Snapshot becomes available.
