The data content of all 77 databases are described on our Content Statistics page while the data sources and methods for each database's contruction are listed on the Databases Overview page

Past releases are described in the Release Notes Archives and Databases Overview Archives


Overall Highlights: 

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



Sweet orange

Sugar beet

Madagascar periwinkle

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 ( or EnsemblPlants (

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 The preprint of the maize B73 RefGen_V4 genome paper can be found at
