A primary goal of the POC is to develop simple yet robust and extensible controlled vocabularies that accurately reflect the biology of plant structures and developmental stages. These provide a network of vocabularies linked by relationships (ontology) to facilitate queries that cut across datasets within a database or between multiple databases. The current version of the ontology integrates diverse vocabularies used to describe Arabidopsis, maize and rice (Oryza sp.) anatomy, morphology and growth stages. Using the ontology browser, over 3500 gene annotations from three species-specific databases, The Arabidopsis Information Resource (TAIR) for Arabidopsis, Gramene for rice and MaizeGDB for maize, can now be queried and retrieved.}, issn = {1531-6912}, doi = {10.1002/cfg.496}, author = {Jaiswal, Pankaj and Avraham, Shulamit and Ilic, Katica and Kellogg, Elizabeth A and McCouch, Susan and Pujar, Anuradha and Reiser, Leonore and Rhee, Seung Y and Sachs, Martin M and Schaeffer, Mary and Stein, Lincoln and Stevens, Peter and Vincent, Leszek and Ware, Doreen and Zapata, Felipe} }
