- Key message
- In this study, we characterized a MIKC-type MADS box gene, CHIMERIC FLORAL ORGANS (CFO1), which plays a key role in the regulation of floral organ identity in rice (Oryza sativa)
- The cfo1 mutant displayed defective marginal regions of the palea, chimeric floral organs, and ectopic floral organs
- The expression domains of CFO1 were mainly restricted to the marginal region of the palea and inner floral organs
- The floral organ identity gene DROOPING LEAF (DL) was expressed ectopically in all defective organs of cfo1 flowers
- Double mutant analysis revealed that loss of DL function mitigated some of the defects of floral organs in cfo1 flowers
- We propose that the CFO1 gene plays a pivotal role in maintaining floral organ identity through negative regulation of DL expression
- OsMADS32 interacts with PI-like proteins and regulates rice flower development.
- OsMADS32 is a monocot specific MIKC(c) type MADS-box gene that plays an important role in regulating rice floral meristem and organs identity, a crucial process for reproductive success and rice yield
- This work provides new insight into the mechanism by which OsMADS32 regulates rice lodicule and stamen identity, by interaction with two PI-like proteins via its K domain

- CFO1~OsMADS32, OsMADS2, OsMADS32 interacts with PI-like proteins and regulates rice flower development., By yeast two hybrid and bimolecular fluorescence complementation assays, we revealed that the insertion of eight amino acids or deletion of the internal region in the K1 subdomain of OsMADS32 affects the interaction between OsMADS32 with PISTILLATA (PI)-like proteins OsMADS2 and OsMADS4
- CFO1~OsMADS32, OsMADS4, OsMADS32 interacts with PI-like proteins and regulates rice flower development., By yeast two hybrid and bimolecular fluorescence complementation assays, we revealed that the insertion of eight amino acids or deletion of the internal region in the K1 subdomain of OsMADS32 affects the interaction between OsMADS32 with PISTILLATA (PI)-like proteins OsMADS2 and OsMADS4
- CFO1~OsMADS32, OsMADS1~LHS1~AFO, Genome-wide targets regulated by the OsMADS1 transcription factor reveals its DNA recognition properties., We show that the expression status of these nodal factors can be altered by inducing the OsMADS1-GR fusion protein and present a model for a regulatory cascade where the direct targets of OsMADS1, OsbHLH108/SPT, OsERF034 and OsHSF24, in turn control genes such as OsMADS32 and OsYABBY5
