Defective in meristem silencing (dms) mutants.

From the forward genetic screen for mutants defective in RdDM and TGS of a GFP reporter gene in root and shoot meristems, we originally retrieved 115 mutants that were fertile and could be propagated. The mutated gene has been identified in 99 mutants that can be placed into nine complementation groups - DMS1 to DMS9 - which are described here by their common name, Arabidopsis Genome Initiative (AGI) number and function in the RdDM pathway. The number of alleles obtained for each mutant is shown in third column. Four mutants contain structural rearrangements of the silencer locus, leading to loss of GFP silencing in the absence of a second site mutation (not shown). The remaining, unidentified mutants do not correspond to DMS1 to DMS9 or to AGO4.
