Best instance selection (2019-01-07)
We have implemented a new tool to find the best PLAZA instance for your species of interest. This tool is available from the PLAZA portal page, and will give an overview of all the PLAZA instances containing your species of interest, together with the various assembly and annotation versions.
Data Warehouse API (2018-10-13)
We have integrated a global PLAZA API system which will query all public PLAZA instances, and return the FTP data storage for each PLAZA instance.

PLAZA 4.0 release notes (2017-09-01)
PLAZA 4.0 is the latest iteration of the PLAZA framework consisting of two instances: Dicots 4.0 and Monocots 4.0. The total number of species across both instances nearly doubled from 37 species in PLAZA 3.0 to 71 species in PLAZA 4.0, with a much broader coverage of crop species (e.g. wheat, palm oil) and species of evolutionary interest (e.g. spruce, Marchantia).

New features include
  • New and improved visualizations for multiple sequence alignments, phylogenetic trees (PhyD3) and gene collinearity (interactive WGDotplot & SyntenyPlot)
  • An Interactive Phylogenetic Module allowing users to create custom phylogenetic trees by using the PLAZA platform as reference
  • Access by an application programming interface (API) through a RESTful web service
  • Improved management of Workbench experiments between different users

If you notice bugs or issues, feel free to contact us.
Move from http to https (2017-08-01)
Due to security concerns all PLAZA instances will now automatically make use of the secure http protocol (https).
Conserved TF binding sites added to PLAZA Dicots 3.0 (2016-06-01)
Based on our recent paper 'A Collection of Conserved Non-Coding Sequences to Study Gene Regulation in Flowering Plants' (Van de Velde et al., 2016), PLAZA Dicots 3.0 now hosts conserved transcription factor (TF) binding site information for >600 TFs. Apart from identifying for any TF target genes with a conserved binding site in ten different species, also the associated gene families and Gene Ontology/InterPro annotations can be browsed. Reversely, for every gene the conserved TF binding sites in the upstream/intron/downstream non-coding can also be retrieved.
The TF binding sites are available for the following species: Arabidopsis thaliana, Brassica rapa, Populus trichocarpa, Glycine max, Prunus persica, Cucumis melo, Eucalyptus grandis, Vitis vinifera, Solanum lycopersicum, Solanum tuberosum

For more examples, please see our tutorial Browsing conserved TF binding sites.
PLAZA 3.0: bug fix BHI orthology (2016-03-01)
Dear PLAZA users,

we want to inform you that we identified and corrected a software bug in one of the tools used in PLAZA 3.0 to compute integrative orthology.
Specifically, for the Best-Hits-and-Inparalogs (BHI) method, we found that while the Best Hits in other species were correctly scored, inparalogs were not correctly identified. This means that no genes were incorrectly identified as being orthologous, but that some orthologs might have been missed (no false positives, some false negatives).

This issue has now been resolved and the data in he PLAZA 3.0 Dicots and Monocots databases and the corresponding FTP download sections have been updated.

Apologies for any inconvenience caused, The PLAZA team
Update PLAZA 3.0 Monocots integrative orthology (2016-06-26)
We want to inform you that the PLAZA 3.0 Monocots website has been updated, now including additional integrative orthology information for Oryza sativa (osa). Downstream data types, incl. orthology-based GO projection as well as the functional annotations for Monocots 3.0 Workbench experiments, have also been updated.
PLAZA 3.0 unavailable Friday 12 Dec 2014, 12-14 CET (2014-12-11)

We want to inform you that the PLAZA 3.0 websites will be unavailable Friday 12 December 2014, between 12-14h CET.

We will perform some maintenance operations fixing missing bootstrap values in the phylogenetic trees as well as updating depending data types.

For all PLAZA 3.0 Workbench users, the functional gene annotations of your experiments will be automatically updated. Note that some minor differences in gene functions might occur due to the orthology-based projection.

Apologies for any inconvenience caused by these operations.

Best regards, the PLAZA team
Building PLAZA 3.0 (2013-12-02)
We are currently in the process of building PLAZA 3.0. This upcoming release will include several new species like tomato, potato, rapeseed, ... While building a new plaza release there is a considerable extra load on the database. Because of this the website might respond slower. This is only temporary.
Thank you for participating in the PLAZA survey. (2013-03-19)
We would like to express our gratitude to everyone who participated in the PLAZA survey. If you have any more questions or remarks, you can send them
View all colinear gene pairs (2012-08-14)
We have added a new feature on the Gene page to rapidly explore all colinear gene information across species. See the function 'View all colinear gene pairs' or check this example!
PLAZA 3.0 roadmap (2012-04-07)
The PLAZA team is currently working towards the 3.0 release of the PLAZA platform and we're looking for user input! What new genomes and features would you like to see incorporated? Are there any other improvements that you would like to see? Contact us at
PLAZA is tip of the week on openhelix (2011-12-01)

"Plaza, a resource for plant comparative genomics, has a lot more than meets the eye at first. Currently the database has comparative tools and data for nearly 2 dozen plants including monocots, dicots, mosses and algae..."

PLAZA 2.5 online (2011-09-10)
The third release of the PLAZA platform, designated version 2.5, is currently available. New genomes include strawberry (Fragaria) and cacao (Theobroma) while several other species, like Arabidopsis thaliana, Zea mays and Brachypodium distachyon, have been updated.

The current release includes >900,000 genes from 25 species, yielding 22,350 multi-species gene families.

New tools include the Circle Plot, a multi-species WGDotplot, a Gene Family Finder, Expansion Plot, and an Integrative Orthology Viewer to explore orthologous genes in other species by combining different orthology prediction methods.

Workbench experiments from PLAZA 2.0 can be transferred to PLAZA 2.5.
Detection orthologous genes (2010-12-01)
Through the integration of a complementary set of data types orthologous gene relationships are inferred. The rationale of combining multiple approaches is to generate a consensus view of gene orthology between different species.

This new tool can be accessed via the Gene page and Workbench.
Apple genome published (2010-09-15)
The apple genome has been published in Nature Genetics. The article can be found here.

Assembly and annotation of the apple genome are included in PLAZA 2.0.

Genome Browser AnnoJ (2009-08-30)
AnnoJ has been integrated as PLAZA's Genome Browser. Currently all gene models together with a DNA sequence track are available.
Workbench activated (2009-08-12)
We have developed a Workbench where for user-defined gene sets different genome statistics can be calculated. For genes sets saved by the user detailed information about functional annotations, associated gene families, block and tandem gene duplicates, and gene structure is provided. The GO enrichment tool makes it possible to determine if a user-defined gene set is over-represented for one or more GO terms. Please check the Help >> Tutorial section for more details.
Tutorials (2009-05-01)
Several tutorials have been added to show how the different functions of the PLAZA platform can be accessed.
The introduction covers some basics like how to find genes you're interested in. The other tutorials cover more complex topics : Gene family evolution, Genome evolution, Functional annotation and PLAZA's Workbench.

The tutorials can be found here.
