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.

Clade

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

Tiers

The different genomes in WormBase are classified in various tiers which depend on the amount of curation effort we are able to put into maintaining them.

Tier I - All efforts are made to curate the gene structures and any other genetic or metabolic information. Only C. elegans is in this group.

Tier II - Efforts are made, where practical, to manually curate the gene structure and possibly some other genomic information. WormBase 'owns' the assembly in the ENA and GenBank so that new gene annotations can be submitted to the ENA/GenBank by WormBase.

Tier III - No curation by WormBase. We will set up the genome on WormBase with any gene structures that the authors of this genome have predicted.

Tier IV - No curation by WormBase. Only transcriptome information provided by the authors and no coherent genome.

Tier V - No curation by WormBase. Only genome information provided by the authors and no coherent transcriptome.

Genome

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.

Gene

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

Assembly

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

Phylogeny

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);
