WormBase Genomes

This is a record of the current and proposed set of genomes in WormBase.

We may, of course, alter our plans for which species to include as circumstances dictate and so the list of organisms which should be included should be treated as somewhat tentative.

The following are some of the columns in the Genome Table.


The Major Clades of Blaxter et al 1998 ("Bclades"), as systematised by De Ley and Blaxter 2002-2004.


The origin of the gene-set. One of: Curated (curated by WormBase), Predicted (made by a gene-prediction pipeline), External (produced by another group), None (no gene-set available).


The Genome column in the table gives the assembly size and a link to the genome in WormBase, or the approximate size if it has not been assembled.


The Genes column in the table indicates whether gene structures have been added to WormBase.


Which lab did the assembly. The sequence coverage. The number of Supercontigs. The Supercontig N50. And anything else that we know about it.

The current genomes

Clade Species NCBI Taxon Genome Gene-set Assembly Comments
V Caenorhabditis briggsae
strain AF16
6238 108419768 bp Curated WashU First added in WS132
[Sept 2010] New assembly from Erich Haag being worked on.
[Feb 2011] updated in WS224
V Caenorhabditis species 9
strain JU1422
870437 204396809 bp External WashU
Supercontigs: 7636
N50: 196652
First added in WS226
[Dec 2011]Update on contamination: There is no evidence that C. sp. 9 underwent cross-contamination, and the "C sp. 7" contaminants in the sp. 9 genome and transcriptome may actually be sp. 9 contaminants which got put into sp. 7.
[Feb 2012] Warning The C. species 9 assembly in WormBase WS226-WS230 has some confirmed contamination by C. species 7. Since species 9 has mostly species 9 genes and some species 7 genes, there is actually added value to having it, as long as people know of the potential problem with "apparent paralogs" that are actually sp. 7 genes.

Given my understanding of the current phylogenetic literature (and based on personal communications with Karin Kiontke,David Fitch and Mark Blaxter), the correct guide tree would be:

((((((((((((C.briggsae,C.sp9),C.sp5),C.remanei),(C.sp11,C.brenneri)),C.elegans),(C.sp7,C.japonica)),C.angaria),(H.contortus,H.bacteriophora)),P.pacificus),((M.incognita,M.hapla), (S.ratti,B.xylophilus))),(A.suum,B.malayi)),T.spiralis);
