- Key message
- Whereas Arabidopsis drm1 drm2 double mutants showed no morphological alterations, targeted disruptants of rice OsDRM2 displayed pleiotropic developmental phenotypes in both vegetative and reproductive stages, including growth defects, semi-dwarfed stature, reductions in tiller number, delayed heading or no heading, abnormal panicle and spikelet morphology, and complete sterility
- Our results suggest that OsDRM2 is responsible for de novo, CG and non-CG methylation in rice genomic sequences, and that DNA methylation regulated by OsDRM2 is essential for proper rice development in both vegetative and reproductive stages
- Impaired growth and abnormal DNA methylation of osdrm2 disruptants were restored by the complementation of wild-type OsDRM2 cDNA

- Connection
- OsDRM2, OseIF4A, De novo methyltransferase, OsDRM2, interacts with the ATP-dependent RNA helicase, OseIF4A, in rice, Deletion analysis reveals that interaction between OsDRM2 and OseIF4A is specifically mediated through ubiquitin-associated domain of OsDRM2 while, both domains 1 and 2 of OseIF4A are critical for mediating strong interaction with OsDRM2 in vivo
- OsDRM2, OseIF4A, De novo methyltransferase, OsDRM2, interacts with the ATP-dependent RNA helicase, OseIF4A, in rice, Interaction between Arabidopsis eIF4AI and eIF4AII with OsDRM2 and nuclear localization of these complexes suggests possible conservation of functional interaction between de novo methyltransferases and the translation initiation factor, eIF4A, in RdDM across plant species
