New PMN releases! - PlantCyc 3.0, AraCyc 6.0, and PoplarCyc 1.0

The Plant Metabolic Network is pleased to announce new releases of the metabolic pathway databases AraCyc 6.0 and PlantCyc 3.0, plus the inaugural release of PoplarCyc 1.0

This PMN release includes many updates to AraCyc enzyme/reaction assignments based on a new PMN enzyme annotation pipeline, plus, 34 additional pathways have been added to AraCyc 6.0.

PoplarCyc 1.0 was created by applying the PMN enzyme annotation pipeline to the Populus trichocarpa 1.1 genome release sequences provided by JGI, and then using the Pathologic software from SRI International. The new computationally predicted database was then validated by PMN curators. 321 pathways and 3434 predicted poplar enzymes are now available in PoplarCyc 1.0. The data have also been incorporated into PlantCyc 3.0. In addition, 75 new pathways have been added to the new version of PlantCyc.

The PMN also now provides a BLAST tool and two customized enzyme sets for PMN users.

PlantCyc 2.0 and AraCyc 5.0 release!

These releases contain many new pathways, enzymes, reactions, and compounds!

A few highlights . . .

  • PlantCyc 2.0 has a whole new set of predicted enzymes from Medicago, tomato, and rice mapped onto the metabolic pathways and more . . .
  • AraCyc 5.0 has new compounds identified through the NSF 2010 Metabolomics Project and from the KNApSAcK database and more . . .
  • You can read about all the new data and features in the PlantCyc and AraCyc release notes.
  • New downloads of the database files are available for registered users. Please sign-up today if you would like to access these valuable resources.
  • We are grateful for help from our contributors in the scientific community.

New easy access to PlantCyc species

Have you ever wondered what information PlantCyc has about apples, bluebells, or carrots? To find out more, please come visit the newly created PlantCyc species page found on the "Databases" submenu.

  • Quickly link to all of the pathways with curated information for your favorite species
  • Browse through the list of over 250 species, from Abies grandis to Zingiber officinale
  • Help the PMN expand its species coverage by contributing pathway, reaction, or enzyme information for even more plants

PMN launches PlantCyc 1.0

On June 17, 2008, PlantCyc made its web debut, containing biochemical pathways from over 250 plant species. The multi-organism database brings together more than 2000 reactions, and includes a total of over 500 pathways.

PMN Roadshow . . . come make connections at upcoming conferences

An important part of the PMN mandate is to encourage interactions and data exchange within the metabolic research community. So, please come meet the PMN staff, give us feedback, and learn about how PMN can help your research at the following conferences in the summer of 2008:
