Details for Planteome Release Version 4.0 October 2020

(Go back to Documents page)

The Planteome Project (http://planteome.org/) is pleased to announce the latest release of the annotation database and ontology files. In this Planteome Version 4.0, there are 59,827 ontology terms, 3,060,530 data objects (bioentities) and 19,838,934 associations between bioentities and ontology terms. The Planteome database contains data from 124 plant taxa.

Updates and changes to Annotations:

Gene Ontology annotations based on InterProScan and via orthology from InParanoid were updated to newer versions of the gene sequences. Several new species have been added. The full list is available on the Link to Annotations by Taxa page. Other annotation files were updated if a newer version was available. All annotation files are available on the Planteome SVN Repository.
