Latest Fugu Assembly Available in Genome Browser

The UCSC Genome Browser now includes the latest release of the Fugu genome. The v4.0 whole genome shotgun assembly (Oct. 2004, UCSC fr2) was provided by the US DOE Joint Genome Institute (JGI) as part of the International Fugu Genome Consortium led by the JGI and the Singapore Institute of Molecular and Cell Biology (IMCB).

This version has been sequenced to approximately 8.5X coverage. The assembly contains 7,213 scaffolds covering 393,312,790 bp. The UCSC browser displays the scaffolds on the virtual chromosome chrUn with gaps of 1,000 bp between scaffolds. The scaffolds range in size from 2,223 bp to 7,245,445 bp. Fifty percent of the sequence (196,648,171 bp) is contained within 125 scaffolds of size 858,115 or greater (N50). The Fugu mitochondrial sequence is also available as the virtual chromosome chrM (GenBank accession: NC_004299.1).

Bulk downloads of the sequence and annotation data are available via the Genome Browser FTP server or Downloads page. These data have been freely provided by the JGI for use in the UCSC Genome Browser.

Many thanks to the JGI, IMCB, and the International Fugu Genome Consortium for the assembly data. The UCSC Fugu Genome Browser was produced by Cory McClean, Hiram Clawson, Ann Zweig, and Donna Karolchik. The annotation tracks were generated by UCSC and collaborators worldwide. See the Credits page for a detailed list of the organizations and individuals who contributed to this release.
