Gene Symbol
- Os09g0306800 <=> OsEMF2b,EMF2b
Function
- OsEMF2b is a regulator of flowering transition and floral organ identity in rice.
- OsEMF2b acts as a Regulator of Flowering Transition and Floral Organ Identity by Mediating H3K27me3 Deposition at OsLFL1 and OsMADS4 in Rice.
Phenotypic analysis
- The OsEMF2b T-DNA insertion mutations and RNA interference transgenic plants cause late flowering, whereas OsEMF2b overexpressing lines result in early flowering. The transcript levels of genes involved in rice flowering pathway differ in wild-type plants and osemf2b mutants.
- The transcripts of Ehd1, Hd3a, and RFT1 decrease, whereas the expression level of OsLFL1 increases in the osemf2b mutants under short-day and long-day conditions.
- Chromatin immunoprecipitation analyses showed that OsEMF2b was directly associated with OsLFL1 and OsMADS4, such that the H3K27me3 was enriched on these target genes chromatin in WT but not in the OsEMF2b RNAi plants.
