Registration is open for the 25th International Conference on Yeast Genetics and Molecular Biology. The meeting will take place on July 11-16 in Olsztyn-Kortowo, Poland. Visit the conference website to get more information and to register. SGD is having a workshop on July 12 at 7:30 PM; come learn about new tools and data at SGD.

In an effort to provide a comprehensive view of all of the sequence-based functional elements in the Saccharomyces cerevisiae genome, SGD will collect sequence-based functional feature annotations from published datasets, aimed at charting the yeast transcriptome (e.g. protein-coding genes, non-coding RNAs), chromatin landscapes (e.g. nucleosome phasing, histone modifications and variations), as well as cataloging regulatory sequence elements (e.g. transcription factor binding sites, splicing signals) and more.
We have upgraded our GBrowse genome viewer to allow users to quickly and easily browse this information-rich view of the yeast genome. In addition, 17 new data tracks have been added, including recent surveys of the budding yeast transcriptome (Nagalakshmi et al. 2008; Xu et al. 2009; Yassour et al. 2009) and catalogs of regions favored for recombination and replication events (Mancera et al. 2008; Buhler et al. 2007; Xu et al. 2006; Eaton et al. 2010). We invite authors to work with us to integrate their data into our GBrowse viewer pre- and/or post-publication as we move forward. Watch for the regular addition of new tracks to SGD’s GBrowse in the future! Please contact us if you are interested in participating or have questions and comments.

Expression analysis at SGD has a new powerful interface and many new datasets. The new interface uses a tool called SPELL (Serial Pattern of Expression Levels Locator). This analysis tool facilitates the rapid identification of the most informative datasets and co-expressed genes based on patterns of expression shared with the query gene(s). By transitioning to this tool, expression data from a comprehensive collection of almost 400 datasets are now available at SGD. The expression analysis tool can be accessed via the expression tab, the expression summary histogram, and in the functional analysis pulldown located on Locus Summary pages. These new data and the SPELL interface have been provided through a collaboration with the SGD Colony at Princeton University. Thanks to Peter Koppstein, Lance Parsons, and Kara Dolinski for help with data preparation and implementation of SPELL at SGD. SPELL was developed by the Troyanskaya lab at Princeton University (Hibbs et al. (2007) Bioinformatics 23:2692).

SGD’s Batch Download tool will be retired soon, because all of its functions and many more can now be accomplished via YeastMine, which offers flexible queries and fast retrieval of multiple datatypes from SGD for a custom list of genes or proteins. Please contact us if you have any concerns.

YeastMine, a powerful data search and retrieval tool, has been upgraded to InterMine version 0.95. This software update includes many new features, improvements and bug fixes. Key new features include a completely redesigned homepage, a more powerful multifaceted keyword search and template ranking by frequency of search. YeastMine queries multiple datatypes: chromosomal features, protein features, GO annotations, phenotypes, interaction data and curated literature. YeastMine will soon replace several search tools at SGD. Please explore its powerful query options and send us feedback.
YeastMine was created through an NIH funded collaboration between InterMine, the Rat Genome Database (RGD), and the Zebrafish Model Organism Database (ZFIN) to provide interoperability between model organism databases.

The budding yeast Saccharomyces cerevisiae reference genome sequence was updated today. This is the first major update of the S288C reference sequence since 1996, and 194 proteins have changed as a result of this update. The new version, called “S288C 2010”, was provided by Fred Dietrich of Duke University, and was determined using new high fidelity sequencing from an individual yeast colony. This update increases accuracy by using modern sequencing technology (Illumina HiSeq) and provides a valuable resource that will serve as the reference point from which to expand our annotation of additional S. cerevisiae strains. In the very near future, SGD will provide researchers with the genome sequences for several commonly used laboratory strains. This is a very exciting time. We will soon have the sequence of all major laboratory strains and hundreds of wild and commercial isolates. Comparative genomics with so many well-studied S. cerevisiae strains and closely-related species will enhance the awesome power of yeast genomics.
