Figures & data
Figure 1. A cartoon illustration depicting different DCL protein components involved in intracellular (local) and systemic antiviral silencing against PVX in A. thaliana. DCL4 is sufficient and essential for the inhibition of viral multiplication in inoculated leaves (Inoc.), whereas DCL2 specifically functions in preventing viral systemic infection (Sys.), possibly during viral phloem transport and/or unloading from sieve elements. In roots, DCL4 is the primary DCL protein component involved in intracellular antiviral silencing, but can be functionally compensated for by DCL2 or possibly partially, DCL3.Citation13
