YGOB Versions & Associated Papers
Version 7  (Aug2012)  Latest DATA
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. Species Phylogeny
  6. GenBank Annotations
  7. 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 http://ygob.ucd.ie
Version 6  (Dec2011) DATA
Added in December 2011 and including six new genomes sequenced by our laboratory: Tetrapisispora phaffii, Tetrapisispora blattae*, Naumovozyma dairenensis, Kazachstania africana*, Kazachstania naganishii*, and Torulaspora delbrueckii. We also added our complete sequence of Naumovozyma castellii (which was previously draft sequenced by Cliften et al. and called S. castellii), and the genome Eremothecium cymbalariae (Wendland and Walther G3 2011). There are now 18 genomes in YGOB as well as the ancestral gene order. This version has some further small changes to the visual interface to improve clarity with so many genomes. To save vertical space, some genomes are not displayed by default and must be turned on using the menus at the bottom of the screen.

* These 3 genomes are draft annotations. The temporary annotations are labelled with the letter X instead of the correct species initial (XAFR, XNAG, XBLA).
