New Strain Sequences Available

December 12, 2012

SGD has incorporated two new S. cerevisiae strain genomes: CEN.PK113-7D and ZTW1. CEN.PK113-7D is a laboratory strain derived from parental strains ENY.WA-1A and MC996A, and is popular for use in systems biology studies. ZTW1 was isolated from corn mash used for industrial bioethanol production in China in 2007. We have also incorporated an updated genomic sequence for W303-derivative K6001, a key model organism for research into aging. The previous version of W303 was an early view courtesy of Markus Ralser. SGD has updated the ORF DNA and protein sequence alignments to include these two additional strains, and the updated W303. We have also included the new genomic, coding, and protein sequences in both the BLAST Search and Pattern Matching (PatMatch) tools. The alignments are accessible via the Analyze Sequence section on the Locus Summary pages. Also available are retrieval and download options.

Download and Align S. cerevisiae Strain Sequences

October 3, 2011

SGD now has available ORF DNA and protein sequence alignments for dozens of S. cerevisiae strains. The alignments are accessible via a new ‘Analyze Sequence’ section on the Locus Summary pages. Also available are retrieval and download options. Stay tuned in the coming months as SGD continues to develop additional tools for viewing and analysis of these sequences.

Sequence Data for 26 Additional S. cerevisiae Strains Available

September 6, 2011

SGD has updated both its BLAST Search and Pattern Matching (PatMatch) tools to include genomic, coding, and protein sequences from 26 additional S. cerevisiae strains. Look for more updates and tools from SGD for analyses of the S. cerevisiae strain genomes in the coming months.

Reference Sequence Updated

February 2, 2011

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.
