July 1, 2006
20 updates made to the Pseudomonas aeruginosa PAO1 genome annotation.
Updated the gene card page for individual records. Removed hyperlink from unpublished manuscripts in evidence reference section. Also moved GO IDs into the TIGRFAM section since they are mappings from TIGRFAM IDs. This will help to distinguish them from the higher-quality PseudoCAP GO assignments provided by the Gene Ontology Consortium.
Edited links to sequence files on downloads page. Updated the amino acid sequence and intergenic DNA sequence files for Pseudomonas aeruginosa PAO1. Added new integenic sequence file for Pseudomonas aeruginosa PA14.
May 29, 2006
Genome projects table updated. Pseudomonas fluorescens Pf0-1 and Pseudomonas entomophila L48 projects' sequencing status changed from 'Incomplete' to 'Complete'. Added the new Pseudomonas aeruginosa PA7 genome project by TIGR (Sequencing status: Incomplete). Please note that sequences and annotations for these projects have not yet been added to the Pseudomonas Genome Database.
May 12, 2006
New Pseudomonas aeruginosa PAO1 export signal data added based on computational predictions and PhoA fusion studies by Lewenza et al (2005) . Data includes 801 predicted Type I signal peptides predicted by at least 3 of 4 computational methods (SignalP v.3.0's neural network and hidden Markov model implementations, LipoP v.1.0, and Phobius) and 185 Type II (lipoprotein) export signals predicted by LipoP v.1.0. In addition, 24 manually identified Type IV (prepilin peptidase substrate) export signal motifs and 16 manually identified twin arginine transporter (TAT) motifs were added to the database. 1042 proteins predicted by Phobius and/or TMHMM to have at least one transmembrane helix were noted. 295 of the above computationally predicted export signals were validated by alkaline phosphatase (PhoA) fusion screens (Note: A PhoA fusion screen method will of course not identify all exported proteins). All of this data is available under the "structure features" field of a given gene card. For example, search for "PhoA" under the structure features field in a Pseudomonas aeruginosa PAO1 database search, or see an example of the data for one gene card here .
New link to Pseudomonas aeruginosa PA14 non-redundant transposon insertion mutant library under related links.
April 5, 2006

New link to potential human homologs (simple top BLAST hit to human) of Pseudomonas aeruginosa PAO1 proteins under related links section.
New search feature: Ability to filter advanced search results based on presence/absence of a transposon mutant insertion from two libraries (Pseudomonoas aeruginosa PAO1 TN5 lux transposon mutant library generated by the Hancock Lab (UBC) and P. aeruginosa PAO1 phoA/lacZ transposon library generated by the University of Washington Genome Centre). One application of this filter is to return putative essential genes in combination with other search features. We hope to include more transposon mutant libraries for more strains in this filter as they become available.
New field associated with each individual gene card stating if a transposon mutant is available. If so, a link displaying the insertion site in GBrowse is provided.
Updated annotations for Pseudomonas aeruginosa PA14 to include the gi number and a unique sequencing center gene id for each gene. Added a link to each gene's card at the PA14 sequencing center.
March 6, 2006
Finished installing CVS client on server. Web site deposited in remote CVS repository.
March 3, 2006
New ortholog predictions replace reciprocal best blast hit (RBBH) analyses for Pseudomonas aeruginosa PAO1. These are computationally-predicted putative Pseudomonas spp. orthologs based on a high-throughput computational method named Ortholuge that further evaluates previously predicted orthologs (including those predicted using an RBBH-based approach as was the case for these analyses) identifying which orthologs most closely reflect species divergence and may more likely have similar function (view legend). When there is no Ortholuge prediction available, a recriprocal best BLAST hit may be included. This data may be viewed in the context of 6 new tracks in GBrowse.
March 1, 2006

- Output from nucleotide sequence database search is viewable in a list format with links to GBrowse view of each aligned region. Note: A downloadable file containing the full BLAST output including pairwise alignments is still provided with each search.
- Added function that retrieves and displays sequence alignment for individual blast search results when using this interface. The full output including alignments for all results can still be downloaded as a text file from the same page.
New link added to subcellular localization track in GBrowse and subcellular localization entry on individual gene cards. Proteins with a localization rating of Class 2 or Class 3 now contain a link to cPsortDB, a database of computationally-predicted subcellular localization predictions.
Genome projects page updated to include more details (date when strain added to database/date strain last updated in database) and ability to sort. In addition, four new entries (Pseudomonas aeruginosa 2192, Pseudomonas aeruginosa C3719, Pseudomonas aeruginosa clinical isolate pacs416 (early) and Pseudomonas aeruginosa clinical isolate pacs5296 (late)) have been added to this page.
Added ability to export results from updates log search to tab-delimited file. Fields that are exported include locus ID, genome, chromosome, update description, date of update and names of individuals that submitted the annotation to the database.
Edited the Downloads page in order to compact information contained in tables. Added links for download of Pseudomonas aeruginosa PA14 annotation files.
Created separate web page for viewing or editing contents of clipboard. The clipboard can now be accessed through a link called "view my clipboard" at the top right corner of most web pages on this site. In addition, it is now possible to add annotations to the clipboard from the individual gene card pages.
Added option to flip the orientation of gene images, drop annotations and download clipboard annotations to text file from annotation comparison page.
New interface for retrieving genomic DNA sequences as well as DNA or protein sequences for specific ORFs. Using this tool, users can retrieve sequences for any of the genomes in this database.
Overview page updated.
Fixed bugs on geneRecord.jsp and compareAnnotation.jsp pages that prevented linking to pre-formatted blast page when using Internet Explorer browser. Problems arose when attempting to perform blast search using very long nucleotide sequences since Internet Explorer browser has limit on length of query string. Changed form submission method from 'get' to 'post'.
Correction made to Pseudomonas aeruginosa PA14 genomic DNA sequence (error in downloadable FASTA files as well as the nucleotide sequence BLAST database). Previous files on this site contained the reverse complement of the correct genomic DNA sequence. We apologize for any inconveniences this caused.

This should eliminate any confusion associated with comparing the 'All genes with pseudomonas.com links' and 'Intergenic Sequences' tracks in GBrowse.
April 29, 2003
GBrowse views of the original and updated Pseudomonas aeruginosa PAO1 genome annotations are now on-line.
Click here to see the GBrowse view of the updated genome annotations for the first 10Kbp of the genome.
GBrowse (Stein et al. 2002. Genome Res 12:1599-610) is the genome browser component of the GMOD (Generic Model Organism Database) project and is a light-weight, easy-to-use, and easy-to-configure genome browser that allows the user to manipulate and visualize genome annotations as horizontal tracks relative to the genome coordinate system, via an interactive web-page. Some features of GBrowse include the ability to visualize simultaneous bird's eye and detailed views of the genome; scrolling and zooming; search by keywords, base-pair range, or relative coordinates; annotation tracks that are customizable by the user and administrator; third party annotation; storage of settings and preferences across sessions; and extension of functionality via plug-ins. It is expected that these features of GBrowse, particularly the ability for third party annotation, will make it a natural and useful extension to www.pseudomonas.com.
To learn more about GMOD and GBrowse, please see http://www.gmod.org
