Gene Symbol
- Os09g0134500 <=> OsTrx1,SDG723,Trx1,Trithorax1,OsSET33
Function
- Suppression of Oryza sativa Trithorax1 (OsTrx1) delayed flowering time in rice (Oryza sativa).
- The plant homeodomain motif of OsTrx1 binds to native histone H3 from the calf thymus and that OsTrx1 binds to Ehd3 through the region between the plant homeodomain and SET domains.
- The SET domain at the C-terminal end of OsTrx1 has histone H3 methyltransferase activity when incubated with oligonucleosomes.
- OsTrx1 plays an important role in regulating flowering time in rice by modulating chromatin structure.
Phenotypic analysis
- In the PF condition, the ostrx1 mutants flowered at approximately 161 d after germination (DAG), 54 d later than the segregating wild-type plants (Fig. 1, C and D).
- Flowering time of the heterozygous plants did not differ from the wild type, indicating that ostrx1 is a recessive allele.
