New Data:

WS206 includes data from Marcel Tijsterman et al. "Isolation of
deletion alleles by G4 DNA-induced mutagenesis" Nature Mathods (in

 the abstract is :
"Metazoan genomes contain thousands of sequence tracts that match the
G4 DNA signature G3NxG3NxG3NxG3, a motif that is intrinsically
mutagenic, probably because it can form secondary structures during
DNA replication.  Here we show how, and to what extent, this feature
can be used to generate deletion alleles of many C. elegans genes."

The OMA orthology predictions from the OMA Orthologs Matrix Project have been updated to the
June 2009 release.

Inparanoid has been updated to release 7

The cisRed (conserved genomic elements) supplementary GFF files (with
an p-value cutoff 0.05) has been added.  Downloaded from the cisRED

The BLAST database for IPI, yeast, and flybase were updated.

InterPro data was updated to release 22

Genome sequence updates:

New Fixes:

Known Problems:

Other Changes:

Proposed Changes / Forthcoming Data:

added DB_info to Anatomy_term

Model Changes:

Fixed Transposon white space issues.


Quick installation guide for UNIX/Linux systems

1. Create a new directory to contain your copy of WormBase,
	e.g. /users/yourname/wormbase

2. Unpack and untar all of the database.*.tar.gz files into
	this directory. You will need approximately 2-3 Gb of disk space.

3. Obtain and install a suitable acedb binary for your system
	(available from

4. Use the acedb 'xace' program to open your database, e.g.
	type 'xace /users/yourname/wormbase' at the command prompt.

5. See the acedb website for more information about acedb and
	using xace.
