CC -!- FUNCTION: RNA-dependent direct polymerase involved in antiviral
CC silencing. Required for the production of some small RNAs (mainly 21
CC and some 22 nucleotides) derived from the crucifer-infecting
CC tobamovirus (TMV-cg). Required for turnip mosaic virus (TuMV) silencing
CC and accumulation of viral siRNAs. Involved in cucumber mosaic virus
CC (CMV) silencing. Required for the biogenesis of viral secondary siRNAs,
CC process that follows the production of primary siRNAs derived from
CC viral RNA replication. Specifically targets the positive-strand of the
CC 3 RNA genomes of CMV and preferentially amplifies the 5'-terminal
CC siRNAs of each viral genomic RNA. Not involved in the production of
CC siRNAs derived from a single-stranded 336-nucleotide satellite RNA of
CC CMV. {ECO:0000269|PubMed:12650452, ECO:0000269|PubMed:19308254,
CC ECO:0000269|PubMed:19966292, ECO:0000269|PubMed:20190077}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate +
CC RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:14527, Rhea:RHEA-
CC COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395;
CC EC=2.7.7.48;
CC -!- INDUCTION: By salicylic acid (SA) and infection by a crucifer-infecting
CC tobamovirus (TMV-cg).
CC -!- DISRUPTION PHENOTYPE: Upon viral infection, increased levels of TMV-cg,
CC tobacco rattle virus (TRV) and CMV genomic viral RNAs. Reduced levels
CC of TMV-cg-derived small RNAs and CMV-derived siRNAs.
CC {ECO:0000269|PubMed:12650452, ECO:0000269|PubMed:19966292,
CC ECO:0000269|PubMed:20190077}.
CC -!- SIMILARITY: Belongs to the RdRP family. {ECO:0000305}.
