Overall PMN 7.0 Highlights

The August 2012 release includes three NEWLY created databases for Selaginella moellendorffii, Physcomitrella patens and papaya plus a newly regenerated database, ChlamyCyc 2.0 for Chlamydomonas reinhardtii. ChlamyCyc 2.0 brings together the manual annotations made by our collaborators at the Max Planck Institute and the high confidence computational annotations made by the PMN E2P2 pipeline

PMN 7.0 also includes updates to the AraCyc, PoplarCyc, CassavaCyc, CornCyc, GrapeCyc, SoyCyc, and PlantCyc databases.

PlantCyc now houses over 34000 proteins. And thanks to the addition of over 80 new pathways contributed by PMN, MetaCyc, MaizeGDB, and GoFORSYS curators, PlantCyc now connects researchers to over 900 metabolic pathways.

All of the PMN databases can now be explored using the updated 16.0 version of the Pathway Tools software.

We hope that these enhanced resources will be useful to researchers, educators, and students who want to learn more about plant metabolism!

Noteworthy new manually curated pathways:

• A new auxin biosynthetic pathway brings in the latest information about the true function of the YUCCA enzymes in maize and Arabidopsis


• Production of hydrogen by the freshwater algal species, Chlamydomonas reinhardtii is described in a pathway that has implications for biofuel research and production


• A polyunsaturated very long chain (twenty-carbon)fatty acid, eicosapentaenoate made in moss can also be made in humans from the essential fatty acid precursor, alpha-linolenate


• Transient production of a signaling intermediate in Arabidospsis links lipid biosynthesis to cellular response pathways
