DNA methylation is dynamically regulated and correlated with chromatin silencing in plants and mammals.We identified a folylpolyglutamate synthetase FPGS1 by screening for suppressors of the repressor of silencing 1 (ros1) mutation, which causes silencing of both the RD29A promoter-driven luciferase transgene (RD29A-LUC) and the 35S promoter-driven NPTⅡ transgene (35S-NPTⅡ).The fpgs1 mutation releases the silencing of both RD29A-L UC and 35S-NPTII.
