Protein name: Protein FLORAL ORGAN NUMBER2
Gene name: FON2
Organism: Oryza sativa subsp. japonica (Rice)
Family: CLV3/ESR signal peptide family
Source: Plant
Expression: Expressed during the development of the floral organ primordia. No longer detected after the carpel has formed. |Expressed in shoot apical and axillary meristems, but not in other vegetative tissues. Detected in a group of small cells at the apical region
