Dear Colleagues,

Plant Ontology Consortium (POC, http://www.plantontology.org) is  
excited to announce the release 0207 (February 2007) of the Plant  
Ontology Database.  The release notes are available at: http:// 

In this new release, the major difference is that we introduced over  
8000 rice QTL from Gramene Database (www.gramene.org) into POC,  
cereal researchers are encouraged to use PO terms to describe Plant  
Structure and Plant Growth Stages associated with their QTL of  
interest.  One example ( PTHT, QTL for plant height ) can be found at:
