Biogenesis and Biological Activity of Secondary siRNAs in Plants

Figure 5

Differential susceptibility of RNAs for transitivity as such and for the direction of transitivity. (a) RDR and RNA-degrading enzymes compete for aberrant RNA. (b) Possible shielding of RNA from RDR activity by scanning and translating ribosomes.
