Annotated Information
Gene Symbol
- Os11g0595400 <=> fon2, FON4, FON2/FON4
Function
- FON2 encodes a small secreted protein, containing a CLE domain, that is closely related to CLAVATA3 in Arabidopsis thaliana.
Mutation
- Mutations in FON2 cause enlargement of the floral meristem, resulting in an increase in the number of floral organs, although the vegetative and inflorescence meristems are largely normal.
- This action of FON2 requires the function of FON1, an ortholog of CLV1.
Expression
- FON2 transcripts are localized at the apical region in all meristems in the aerial parts of rice plants, showing an expression pattern similar to that of Arabidopsis CLV3. Constitutive expression of FON2 causes a reduction in the number of floral organs and flowers, suggesting that both the flower and inflorescence meristems are reduced in size.
