Annotated Information
Gene Symbol
- Os05g0135700 <=> OsSAMS1
Function
- SAM deficiency suppressing DNA and H3K4me3 transmethylations at flowering key genes led to a late-flowering phenotype in rice. This information could help elucidate the mechanism of epigenetic control flowering transition.
Mutant
- RNA interference (RNAi) transgenic rice with downregulated transcripts of OsSAMS1, 2 and 3 showed pleiotropic phenotypes, including dwarfism, reduced fertility, delayed germination, as well as late flowering. Delayed germination was largely rescued by application of SAM in the knockdown lines. Knockdown of OsSAMS1, 2 and 3 led to distinguished late flowering and greatly reduced the expression of the flowering key genes, Early heading date 1 (Ehd1), Hd3a and RFT1 (rice FT-like genes).
