PMN 15.5 Released!

By Charles Hawkins

We are pleased to announce the release of PMN 15.5! In this release, twenty-five of our databases have been regenerated using updated genome assemblies. We have also updated our backend to Pathway Tools 26.0 and made minor fixes to several databases (fixed broken links, etc.).

The databases updated with new genome releases are:

AhalleriCyc, BarleyCyc, BrachypodiumCyc, CacuminataCyc, CassavaCyc, ChineseCabbageCyc, ChlamyCyc, CornCyc, DrotundataCyc, EuropeanPearCyc, Fvesca_vescaCyc, GrapeCyc, LjaponicusCyc, MtruncatulaCyc, OilPalmCyc, PhalliiCyc, PoplarCyc, PotatoCyc, RchinensisCyc, SfallaxCyc, TeaCyc, TomatoCyc, ValleyOakCyc, WheatACyc, and ZmarinaCyc.

New features from Pathway Tools 26.0 include support for saving most web graphics (such as pathway diagrams, compound structures, and the cellular overview) as PDF, and better default zoom for large pathway diagrams.

PMN Downtime March 15

By Charles Hawkins

Update 2: The PMN databases are now back up. We thank you for your patience during the move.

Update: Due to unexpected difficulties with the server move, PMN downtime has been extended into March 16th. We expect to have PMN back up later today. We again apologize for the inconvenience.

Original Post: Due to a server move, pmn.plantcyc.org (the part of the site that contains the databases), will be down for part or all of March 15th. We apologize for the inconvenience.

PMN 15.0 Released!

By Administrator

We are pleased to announce the release of PMN 15. This release includes a new species, new features, and fixes to existing species:

  • We have released a new pathway genome database, StoraCyc, for the legume Senna tora
  • PMN now uses Pathway Tools 24.0, with new features that include:
    • All pathways that include transport between subcellular compartments are now shown with the compounds moving across the membranes. For example, the glutamate-glutamine shuttle in AraCyc
    • You can now pull up a SmartTable of all pathways, reactions, etc. for an organism right from the organism info page (e.g. this page for AraCyc) by clicking the orange SmartTable buttons next to the database statistics
  • The previous release of OryzaCyc erroneously included old enzyme data alongside the current data. The old data has now been removed

New feature: Metabolic Cluster Viewer

By Administrator

We are pleased to announce the launch of a new website feature, the Metabolic Cluster Viewer. We have run our PlantClusterFinder software on nine of the PMN species' genomes, and the Cluster Viewer allows you to search and view the results without having to download and run the cluster finder yourself. The species currently available are Arabidopsis thaliana, Glycine max (soybean), Medicago truncatula (wild relative of alfalfa), Oryza sativa (rice), Populus trichocarpa (poplar), Senna tora (a wild legume), Solanum lycopersicum (tomato), Vitis vinifera (grape), and Zea mays (maize).

The tool will show a gene diagram of the cluster and a list of genes, with EC numbers and Metacyc IDs of catalyzed reactions and GO terms for each gene. It will also show co-expression data of the genes from the ATTED-II database if available.

The Cluster Viewer can be accessed from the PMN Data menu under PMN Tools, where BLAST has also been moved.

PMN12.5 released

By Administrator

We are pleased to announce PMN12.5 release. In this release we added locus IDs to genes in all PMN databases. The locus IDs were extracted from public genome releases that were used in constructing the PMN metabolic pathway databases. Protein sequence IDs from the genome releases are associated with proteins. The locus IDs, along with protein sequence IDs, should greatly facilitate data query and usage. Additional data cleaning was done to several databases, most noticeably in AraCyc where we removed more than 140 redundant gene entries.

PMN 12.0 released!

By Administrator

We are pleased to announce the PMN12 release. In this release we introduce 54 new species-specific metabolic pathway databases, which brings the total number of species-specific databases to 76.  The 76 species cover the green plant lineage widely, including green algae, a moss, a club moss, a basal flowering plant, and higher plants of monocots and eudicots. They include major crops from grains to vegetables and fruits. Several medicinal plants are also added to this release, such as Madagascar periwinkle (Catharanthus roseus), red sage (Salvia miltiorrhiza) and flax (Linum usitatissimum). The new release also expands the number of species in three plant families: 17 species in Poaceae, 13 in Brassicaceae and 6 in Fabaceae.

Examples of new species-specific metabolic pathway databases:

Bread wheat

Carrot

Spinach

Sweet orange

Sugar beet

Madagascar periwinkle

Please find complete list of databases here.

 

An important note about downloading complete PMN databases:

The following five databases were constructed from genome releases which are under prepublication data usage restrictions and thus can only be accessed by online searching and browsing at the PMN web site: AhalleriCyc (version 1.0) (Arabidopsis halleri), LperrieriCyc (1.0) (Leersia perrieri), ObrachyanthaCyc (1.0) (Oryza brachyantha), OpunctataCyc (1.0) (Oryza punctate), OrufipogonCyc (1.0) (Oryza rufipogon). Please see detailed data policy at the corresponding species page from Phytozome (https://phytozome.jgi.doe.gov/pz/portal.html) or EnsemblPlants (http://plants.ensembl.org/index.html).

CornCyc (version 8.0) was constructed from the maize B73 RefGen_V4 genome release, which is also under prepublication data usage restrictions. We communicated with the genome release provider and was allowed to provide the PMN users full access to the CornCyc database, online browsing and complete download. However we ask that you respect the data usage restrictions posted on http://plants.ensembl.org/Zea_mays/Info/Index. The preprint of the maize B73 RefGen_V4 genome paper can be found at http://biorxiv.org/content/early/2016/12/19/079004.

PMN 11.0 released!

By Administrator

We are pleased to announce the PMN11 release. Highlights include the addition of curated information of rate-limiting steps in over 50 pathways. To see an example, follow this link,

http://pmn.plantcyc.org/PLANT/NEW-IMAGE?type=PATHWAY&object=PWY-695

To see a complete list of pathways with rate-limiting info, follow this link,

http://pmn.plantcyc.org/group?id=pmn-prod.dpb.carnegiescience.edu-1-3673...

Clicking on any pathway from the SmartTable, you will see a pathway diagram where the rate-limiting reaction is indicated with an icon of hourglass. Mouse over the icon to see the literature source of the curated rate-limiting data. We will continue curating and adding available rate-limiting data from the literature.

In this release we removed additional data of macro-molecule metabolism from the PMN databases, including enzymes, reactions and pathways that metabolize or modify proteins, DNAs, and RNAs.

The PMN databases are now updated to the Pathway Tools 19.5 data schema.
