CLAVATA signaling restricts stem cell identity in the shoot apical meristem (SAM) in Arabidopsis thaliana. In rice (Oryza sativa), FLORAL ORGAN NUMBER2 (FON2), closely related to CLV3, is involved as a signaling molecule in a similar pathway to negatively regulate stem cell proliferation in the floral meristem (FM).
==Annotated Information==
===Function===
Here we show that the FON2 SPARE1 (FOS1) gene encoding a CLE protein functions along with FON2 in maintenance of the FM. In addition, FOS1 appears to be involved in maintenance of the SAM in the vegetative phase, because constitutive expression of FOS1 caused termination of the vegetative SAM. Genetic analysis revealed that FOS1 does not need FON1, the putative receptor of FON2, for its action, suggesting that FOS1 and FON2 may function in meristem maintenance as signaling molecules in independent pathways. we have examined the function of the gene FLORAL ORGAN NUMBER2 (FON2) in Oryza sativa (rice). 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.
===Expression===
Molecular cloning reveals that FON2 encodes a small secreted protein, containing a CLE domain, that is closely related to CLAVATA3 in Arabidopsis thaliana. 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. This action of FON2 requires the function of FON1, an ortholog of CLV1. Constitutive expression of FON2 also causes premature termination of the shoot apical meristem in Arabidopsis, a phenotype similar to that caused by constitutive expression of CLV3.
===Evolution===
a key amino acid residue that discriminates between the actions of FCP1 and FON2.he basic framework of meristem maintenance is conserved in the angiosperms, the functions of the individual factors have diversified during evolution.
==Labs working on this gene==
Constitutive expression of FCP1 results in consumption of the SAM in the vegetative phase, and application of an FCP1 CLE peptide in vitro disturbs root development by misspecification of cell fates in the RAM. FON1, a putative receptor of FON2, is likely to be unnecessary for these FCP1 functions.
