Welcome to the Yeast Gene Order Browser. YGOB is an online tool for visualising the syntenic context of any gene from several yeast genomes. There are detailed user guidelines. Standard bioinformatics tools are available through the browser interface and the icons for each are explained on the help page.

You can start browsing immediately by typing the name of a yeast gene in the control console at the bottom of this page (e.g. ADH1).

The Yeast Gene Order Browser: combining curated homology and syntenic context reveals gene fate in polyploid species
Byrne KP and Wolfe KH
Genome Research. 2005 Oct;15(10):1456-61
Supplemental:  Supplemental Methods  Methods  Supplemental Table 1 - Gene sets, homology, tandem repeats and ohnologs  Table 1  Supplemental Table 2 - Full Ohnolog Lists from S. cerevisiae, S. castellii and C. glabrata  Table 2 
Version 7  (Aug2012)  Latest Earlier versions...
Added in August 2012 and including three new genomes (Saccharomyces mikatae, S. kudriavzevii and S. bayanus var. uvarum) from Scannell et al. G3 (2011) and the finalised versions of the three draft genomes in Version 6. We've updated the S. cerevisiae data in YGOB to the latest release (R64) from SGD. As a visual aid we have also added bars to the top of gene boxes to inidicate the relative length of homologs.

We expect this to be a 'benchmark' version of the browser, suitable for many types of analyses and likely to remain as the current YGOB version for the next few years. Researchers may find the associated datasets listed at the right of use to them.
  1. Homology
  2. Gene Order & Annotation
  3. Genome Sequences
  4. Protein & Nucleotide Sequences
  5. Genus Specific
  6. Species Phylogeny
  7. GenBank Annotations
  8. S. cerevisiae Ohnologs
New Server & Domain Name
With this version we have also migrated YGOB to a new faster and more powerful server, which renders all aspects of YGOB much quicker than before and facilitates heavy traffic and large numbers of simultaneous users. The browser can now be found at
