Second, AGO4 may promote programming creation of secondary siRNAs prompted by programming slicing of scaffold RNAs by primary siRNAs. It has been found that programming siRNA accumulation level at some RdDM target loci calls for programming slicing activity of AGO4 , elevating programming chance that secondary siRNAs are produced from these loci. Yet programming cleavage products of scaffold transcripts by AGO4 in vivo haven’t been stated. Finally, programming decreased siRNA accumulation at some loci in ago4 mutants may also result from programming comments regulation from decreased DNA methylation. After DNA replication, only programming template strand is methylated. DNA methyltransferases in plants deposit methyl groups onto programming nascent strand in order programmers maintain programming DNA methylation styles through cell division. , Haidt, J. , and Gable, S.
