This page summarises recent changes and enhancements that have been made to the AGR database. A full and very detailed list of changes is also described as part of the new AGR help pages that are stored as part of AGR. Click here to read the full list of changes to AGR and to the AceBrowser interface that is used to access AGR via the web.

March 2003

Database rebuilt - 20/03/03
Database includes newly added 57,725 Insert_Salk A Sequence-Indexed Library of Insertion Mutations in the Arabidopsis Genome

November 2002

Database rebuilt - 18/11/02
Database includes new SINS (Sequence Insertion Sites) generated by the Arabidopsis Transposon Insertion Service (ATIS).

May 2002

Database rebuilt - 23/05/02
Database includes ~2600 new SINS (Sequence Insertion Sites) generated by the Arabidopsis Transposon Insertion Service (ATIS). Some of the new sequences are re-sequenced versions of the previous SINS inserts. These old 'pre-release' sequences did not give the defined insertion sites because they did not contain the transposon end in the sequence. They are still viewable but will gradually be removed. Germplasm information for the SINS is available and links into the NASC catalogue.

November 2001

Database rebuilt - 7/11/01
Database rebuilt and now includes homology information to Physcomitrella patens (moss) cDNA sequences generated as part of the Physcomitrella EST Program (PEP). Physcomitrella EST clones can be ordered as part of the PEP service. To view all genomic Arabidopsis sequences which have a homology to a moss cDNA click here.

March 2001

30/03/2001 - New insert sequences
Sequences are now available from the gene trap and enhancer trap lines developed at CSHL by Rob Martienssen. About 500 sequences are available. NASC hope to soon be distributing stocks for these insert lines. These new sequences can be searched against on our insert BLAST server or browsed in AGR.

14/03/2001 - New Arabidopsis BLAST database
There is now the option on our UK CropNet BLAST server to BLAST search against just the set of ESTs in AGR (over 110,000 sequences).

February 2001

07/02/2001 - GeTCID information added to AGR
The GeTCID service (Gene Transfer Clone Identification and Distribution) is run by Ian Bancroft at the John Innes Centre (Norwich, UK) as part of the GARNet project (Genomic Arabidopsis Resource Network). DNA submitted to this service will be screened against four clone libraries and clones that complement the submitted sequence can then be ordered.

The data held in AGR represent the first set of results from the GeTCID service. Submitted probe sequences have been BLAST searched against the Arabidopsis genome sequence and are represented on the graphic displays as purple BLAST homologies.

Because the GeTCID clone libraries can contain quite large inserts (over 100 kb), it is worth noting that if you notice that a sequence in AGR has a GeTCID BLAST homology it is *likely* (though not certain) that *all* of that sequence can be complemented by ordering the corresponding GeTCID clone(s). This may not be the case for the very large (>100 kb) AGI sequences.

January 2001

29/01/2001 - New Arabidopsis species information added to AGR
AGR now represents all Arabidopsis species, and not just Arabidopsis thaliana. Over 20 different Arabidopsis species and subspecies can now be searched in AGR. Both DNA sequences (from EMBL) and protein sequences (from TREMBL) have been added.

22/01/2001 - External database links added
Web links to useful databases have now been added (where relevant) to many objects in AGR. Species names are now linked to the NCBI taxonomy browser for instance. Paper abstracts are now available at PubMed by linking MedLine ID numbers from EMBL entries. Most external links have been made for Sequence and Protein objects which now link to the following databases:

EMBL, GenBank, Mendel-GFDb, InterPro, PROSITE, PRINTS, and Pfam.

The number of links to these databases will depend on the original database annotation. Please note that these links are only active if you use AceBrowser.

12/01/2001 - Improved BLAST server
The UK CropNet BLAST server now allows you to search against all five completed Arabidopsis chromosomes. Very useful for when you want to know where exactly your gene of interest lies. The complete chromosome sequences are available at the MIPS FTP site.

November 2000
NASC have expanded the Insert blast server facility into a new service called InsertWatch. Register sequences with InsertWatch and you will be emailed as and when a new insert sequence matches your submitted sequence. The email will report details of the BLAST match and provide web links for you to order the corresponding insert lines.

October 2000
Database rebuilt with improved interfaces and new data. Try our new Author search pages, or search against the Arabidopsis genome with our BLAST server. Also look at our insert page to see if a knock-out of your favourite gene is available.
