In order to further investigate silencing mechanisms, we screened a mutagenized Arabidopsis thaliana population for expression of SDCpro-GFP, redundantly controlled by DNA methyltransferases DRM2 and CMT3. We identified the hypomorphic mutant mthfd1-1, carrying a mutation (R175Q) in the cytoplasmic ...
