Annotation of the three orthologous sets of flowering time pathway genes from Arabidopsis and rice
The GSO and PSO annotations for Arabidopsis GI, CO, and FT, and rice OsGI, Se1 (Hd1), and Hd3a genes were imported from the PO database. The annotations to GO (columns 4–6) were imported from TAIR and Gramene databases to give an overview on the functional characteristics of the orthologous genes. The curators assigned the ontology terms from the whole growth stage (GSO) and plant structure (PSO) aspect to suggest when and where in a plant these genes were expressed or phenotyped. Depending on the experiment type (evidence code) and citation evidence (references), the databases recorded information about the mutant/gene/gene product to GSO and PSO terms. The same procedure was used for GO annotations. Columns 2 to 6 provide information on the term names, ID, and the evidence code.
