The May 2008 Caenorhabditis elegans assembly is based on sequence version WS190 deposited into WormBase as of 28 May 2008. The sequence was produced jointly by the Wellcome Trust Sanger Institute in Hinxton, England and the Genome Sequencing Center at Washington University in St. Louis (WUSTL) School of Medicine, MO, USA. For more information about this assembly, see WS190 in the NCBI Assembly database.

Sample position queries

A genome position can be specified by the accession number of a sequenced genomic region, an mRNA or EST, a chromosomal coordinate range, or keywords from the GenBank description of an mRNA. The following list shows examples of valid position queries for the C. elegans genome. See the User's Guide for more information.

   Genome Browser Response:

chrII Displays all of chromosome II (valid chr entries include I, II, III, IV, V, M, X)
chrI:1-100000 Displays the first 100,000 bases of chrI
Z81037.1 Displays clone fragment Z81037.1
mec-8 Displays region of genome associated with RefSeq gene mec-8
F46A9.4 Displays the region associated with the Sanger predicted gene F46A9.4
NM_060107 Displays region of genome associated with RefSeq identifier NM_060107
BJ111711 Displays region of EST associated with GenBank accession BJ111711
zinc finger Lists many zinc finger mRNAs
ring zinc finger Lists only RING zinc fingers
thierry-mieg Lists mRNAs deposited by authors named Thierry-Mieg
Jones,D. Lists mRNAs deposited by co-author D. Jones

Use this last format for author queries. Although GenBank requires the search format Jones D, internally it uses the format Jones,D..

Assembly details

C. elegans is a major model organism used for biomedical research. It is the first multicellular animal to have a fully sequenced genome, a joint collaboration between WUSTL and the Wellcome Trust Sanger Institute. For more information see the special issue of Science, "C. elegans: Sequence to Biology". This assembly has a finishing error rate of 1:100,000. The total size of the sequence is 100,281,426 bases in chromosomes chrI, chrII, chrIII, chrIV, chrV, chrX and chrM (mitochondrial sequence).

Bulk downloads of the sequence and annotation data are available via the Genome Browser FTP server or the Downloads page.

The C. elegans browser 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.
